No strobes. my cheapo $30 chinese light doesn't flash, it's a freaking disco strobe, making it useless in flash mode.

But a 1s high / med / high / low modulation would be good. I'm all for making people notice me.

ItsJustMe 10-12-16 04:35 PM

I agree with nyc above. Super rapid strobes are bad and if there's a valid use case for them, I don't know what it is. I have one headlight that has ONLY the seizure mode, so it doesn't get used much, and only in steady mode.

Maybe a 2hz flash is about ideal to me. For attention getting, it could be about 20% duty cycle or even shorter. that is, on 20%, off 80%. Saves battery, just as attention getting as a 50% flash.

"Strobe" means extremely short duty cycle, like a 1/100th of a second on or less. Even if it's only coming on once every 10 seconds, that's still a strobe. Most of the super fast flash modes I see are not strobes, they're just rapid flashing.

I really like the Cygolite strobe. It doesn't flash many times per second (2 or 3) but the flashes are extremely short duration, so they're not blinding, just attention getting. The strobe over steady is particularly nice - it's a steady 500 lumens or so (on my Metro 550) with just very short 50 lumen pulses over the top of that, so you can see by it but it's also attention getting. That's a strobe too, by my definition.

Which Cygolite Strobe is that?

downwinded 10-12-16 06:23 PM

The flash / steady is quite noticeable. Occasionally I meet a guy on my evening commute that uses one. Both my Metro 500 and 300 have the feature. But, I don't like to use it in the dark or even dusk. It's just too "nervy" for me!

The Metro 550. The strobe mode on it is very short pulses, 3 or 4 per second. The strobe over steady is nice too, it's 5 very rapid pulses then a pause, repeated once per second, over the normal power of the steady light.

No offense intended, but I'm not asking anyone to Google "lights" for me. The problem is, everything looks awesome in photographs, whether it has a $2 price tag or a $200 price tag. I started this thread primarily to see what people think about the idea of daytime lights -- not so much which lights I should buy. I'm only going to upgrade if enough people can support my hypothesis that daytime lights are important and that the basic ones I already have are not good enough.

Thank you again for providing those links, though. To me, they look kind of cheaply made. Have you actually seen or used either of those sets?

No offense taken. I'm sure they are extremely cheap, going by the prices. So, have you learned what you wanted from 75 people with 82 different opinions? :D
I often use my lights on my ride home on the highway, particularly my tail light. Always in flash-flash-pulse mode, because a steady light would be near invisible in full daylight, but motion will catch drivers' attention (assuming they look up from their phones once in a while). I wear hi-viz shirts, so the light is just a see-me. HTH

True; I was just too lazy to search more thoroughly. :)

You know, I make the same mistake on these forums over and over again. I hate wading through gigabytes and gigabytes of prejudiced online ads, reviews, and opinions, so I ask a question of the readership thinking there's actually going to be some kind of consensus on an answer. That way, I can just go out and mindlessly do what everybody tells me to do. But there's more than one way to skin a cat - or in this case, a Cat-Eye (rim shot/cymbal crash) - and maybe ALL the answers that have been posted are "correct."

I started this thread because I've been seeing A LOT of riders using daytime lights. In fact, all of a sudden, I feel like I'm seeing riders where I never saw them before, so maybe they just blended into the scenery before they decided to light up. Perhaps I answered my own question. I want to be seen on the road during the day, especially on foggy mornings like today, and I really believe daytime lights can help.

I am still not sure whether it would be worth the investment to switch to a flashing headlight, but now I know there are steady headlights that also pulsate, and I'm very interested in that option. I don't find flashing lights offensive, but I respect that some people might. If I ever go out on the road using one and someone shouts at me like "WTF?" I always have the option of turning off the flashing option.

So I thank everyone for their input, but that's probably enough for now. There are already way too many options to consider and now I'm feeling paralyzed about making a decision. One of these days, though, I'll be in a shop with some money burning a hole in my pocket and I'll impulsively buy any old light (under $25 or so) that catches my eye and I'm sure it will be just fine - definitely better than what I have.

So what is your conclusion so far?

Personally I'm ambivalent. I'll run the headlight if I have it and I'm not saving the battery for later, but I don't sweat it if I don't.

no motor? 10-15-16 10:10 AM

I only run my lights when I wear my helmet, and I only wear my helmet if I think there's the possibility that the protection it offers would be beneficial. I've gotten many many comments over the years about my lights too, and they're all been really positive with people saying things like they noticed me way sooner than the people that don't use lights.

Archwhorides 10-15-16 01:51 PM

For the past year I have been running fixed "marker lights" on the front and rear for daytime and night-time general roadway use, and have a separate strap-on torch to light the MUP or dark roads at night-time. These lights do not fit the OP's budget, but FWIW, here they are:

1. Front and rear markers: Sparse.cc "fixed light" system
2. Light and Motion 500 lumen torch with a custom light-shielding cowl.

The Sparse fixed lights are great as marker lights, because they are difficult to steal (2 years on my urban bike so far), so no need to fuss with taking them on and off, also they have various blinking and steady modes and are USB charged.

The Sparse headlight is not good for lighting the road however, therefore my need for the separate torch.

No real conclusion. That's my point in Post #98, I suppose.

Today, I went to check out some rear lights at a pretty large LBS. As expected, the salesperson knew absolutely nothing about the thousands of dollars worth of lights on display in the middle of the store and suggested that I research them on the Internet. This is why I rarely ever actually BUY any of the things I ask about on these forums.

One thing I noticed: Most of the rear lights have cheapo little clips now, rather than hardware to mount them on a rack. I'm wondering if I should just wait until I find the light I want on the side of the road.

Mine is zip-tied to the seat stays. The other has a zip-tie around the clip on the rack plate, so I don't really care how secure those clips are. I figure as long as I have red blinking, and it won't fall off, then I'm golden.

Users think they really grab the attention of oncoming traffic; true, but they make it hard to see anything else.

Please re read OP's post. Daytime use. They are not brighter than the sun. Try sunglasses and/or look away for a few seconds.

In my area many MUPs are closed at night anyway but people still use them. Pedestrians that are walking on the MUP without lights but under the benefit of "real" night vision are immediately plunged into darkness when exposed to any light...low intensity or otherwise. And it takes from 30 to 45 minutes for them to readapt their night vision to the level it was before. It may take 15 to 20 minutes to be able to see well enough to stumble along.

Even if you are running a light that puts out 50 lumens...which is really, really dim...you've ruined the night vision of someone who isn't using lights. More light doesn't change that equation, so I avoid using MUPs at night time. It's the courteous thing to do.

[FONT=Calibri][SIZE=3]

Perhaps the Denver metro area is darker than other cities but I really doubt that based on my experiences in other parts of the US. That said, there are enough dark places on my commute to and from work along "lighted" streets, that having a "flashing light pointed...at the road surface" would mean that I'd have significant stretches of dark riding and pothole surprises.

On the other hand, if I'm riding in a well-illuminated area, I want to be noticed by the drivers. I'm not worried about their night vision...they don't have any...but I want to stand out against a sea of other light sources. I have no problem with confusing drivers into thinking that I'm another car or a truck or a train off the tracks. When I'm approaching them, I want them to think twice about how big this thing coming at them is and stop to think about pulling out in front of it.

It's kind of the puffer fish approach to riding at night so, yes, my lights are a kind of force shield.

Ugg, agree to disagree. Multi Use Path, that's how peds and bikers get home in the dark around here. Lights 24/7. How am I supposed to see the peds who have no lights or reflective gear? Lights works for me. I run a light on the helmet and a steady and blinking light on the bar. The Boston mups are for commuters, they don't close. No night vision with bikes, houses, cars and street lights. They could just flip the phone they are staring at to light up the ground.

I don't think helmet-mounted lights are much help for making the rider visible at night. I see them only as a disembodied light that doesn't make sense. Not so bad in the daylight, though.

Helmet lights are great for providing a higher light, like say over the roof or hood of a car. Also for the rider, the helmet light can turn with the head to see the turn before the bars do. A light on the bars and helmet make for better depth perception on road bumps and holes. And finally the helmet light can " get " the attention of the idiot drivers. YRMV.

I agree that a helmet mounted light is excellent for helping its wearer to see things, and of course, as you say, the wearer can use it --almost as a weapon-- to get someone's attention. That's all to the good; certainly a useful tool.

My point was something else. Namely that, regardless whether you wear a helmet mounted light, your bike should wear the standard lights that make it recognizable as a bike. The helmet light cannot reliably do that.

Not just the helmet light , bar too. Around here, bike helmet+bar lights are the standard. Add wheel lights too.

From the OP:

OK, so let's say you just received a $50 Amazon gift certificate for donating red blood cells and you plan to spend it (and not a penny more) on a new rear blinkie that will attach to your Topeak MTX rack and will provide kick--ss daytime visibility. In as few words as possible, which rear blinkie do you order?

FYA, I just spent about $50 for a new rear blinkie, posted about it, and got lambasted, even before I used it. Nonetheless, I’m happyabout the purchase, and look forward to posting a rebuttal, after I have usedit (in a couple days).

BTW, I'm familiar with blood transfusions...did you really get a $50 gift certificate of donating "red blood cells"? I believe paid donors have been forbidden for decades now, though I think you may be able to get paid for plasma for non-transfusion purposes.

I don't get paid, but I get "gifts" for being a regular donor and keeping appointments. Mostly DVDs and books, T-shirts and movie tickets, but the biggest gift is a $25 gift card.

Which blinkie did you get? Is it daytime bright?

I did an "Automated Red Cell" donation, as I do every few months without any sort of compensation. This time, they asked me which $50 gift certificate I would like - Amazon, Walmart, Target, Home Depot, or Dunkin' Donuts. Knowing I wanted to upgrade my blinkie, I didn't argue.

The Cygolite Hotshot seems to be a popular one on this forum. But it won't mount to my rear rack, right?

ItsJustMe 10-24-16 07:52 PM

I'd probably buy two lights, an Axiom Pulse 60 ($30) and a Blitzu 168T ($19).

One rear light is NOT ENOUGH.

Put the Axiom on steady down load and the Blitzu blinking on your helmet.

This is what I'm running currently. I've been through a lot of lights and most of them are retired now.

I do have the Fly6 on the back, blinking away too, but it's not a primary light.

Papa Tom 10-25-16 03:45 PM

I wish everything didn't have to be so damned difficult. Cygolite makes a blinkie model called the Hotshot Pro 150 USB for about $43 on Amazon. They also make a bazillion other models, including other Hotshots with the numbers 50, 80, etc after them (which I assume is the lumen rating?).

I want something really bright for daytime riding, but it doesn't have to be brighter than "bright enough." More importantly, I want one that can be mounted to my Topeak Explorer rack, which I know will require some kind of mounting accessory.

Without suggesting lights other than the Cygolite Hotshot, can somebody help me make up my mind and be done with this stupidity already?


ItsJustMe 10-25-16 04:12 PM

Just buy something.

I guarantee that no matter what you buy, you will at some point wish you bought something else. Eventually you'll be like the rest of us and have a dozen taillights and 4 or 5 headlights.

You will NEVER get any kind of consensus here because some people think there's no such thing as bright enough unless you're lighting shrubs on fire as you ride by, and others are afraid of offending light sensitive vampires on the MUP.

Great advice. I really should just go into my LBS, look at no more than three items, and buy one. But in this case, it's sort of an impulse buy based on having a $50 Amazon gift card, so I have to make this purchase without the benefit of actually seeing the thing blink. Most people, in all my research, seem to recommend the CygoLite Hot Shot, so I thought it'd be simple to just buy that. But then I see that there are 5 or 6 Hot Shot models and no good explanations as to how they differ. Plus, I finally get what I thought was an answer as to whether the Hot Shot can be mounted on a Topeak Explorer rack and now I can't confirm that THIS particular Hot Shot will mount to that rack because, apparently, they are all different.

As I said earlier, this is why I never end up buying anything -- and maybe why people don't buy as much as they used to. Hey, bike lighting industry...just give me two choices and I PROMISE I will pick one!!!!!!!

I have 2 tail lights - one for each bicycle.

I also have 2 front lights - same.

No regrets. :) CatEye rear light - any that has at least 3 LEDs in it. Most are rain (and downpoor) resistant.

Front light - on one bicycle I use a flashlight, on a flashlight mount placed on handlebars. Good light, rechargeable AA batteries. On the other, a dedicated bicycle LED battery light.

Cygolite has a rack mount. I don't know if it will fit your rack. Check your rack and the mount eyelets. I don't even know if this mount is compatible with the 150. It probably is. Call cygolite and find out. There is a model number in the amazon listing.

Both the cygolite and niterider offer 150 lumens, very close to the dinotte lights, at a quarter of the price. You will need two tail lights anyway: one for the bike, one for the helmet. Get both. You'll still be paying less than half the price of a single dinotte.

The niterider has better side lighting, while some think the cygo is brighter straight on. Get both and get the best of both worlds.
