With that much stuff, my 2 LED light is still brighter.

What! Brighter then my Serfas TL-1000?
What light do you have ?
Any pic of it on your bike?
Thanks

Which is Brightest: Buick or Bike?

In that super-pixelated Youtube-compressed video, they look about the same.

Bonus points for being visible in daylight, though.

The Cannon A530 seems to take dark pics. Look the same to me.

I have 2 of those, one on the back of the bike and one on the helmet.

The first time my neighbor saw me with it in the morning (from 1/2 mile away) he thought I was a cop or a tow truck. Either way he slowed down.

(this is the planetbike unit)

Just to give you an idea. This is how bright one of those LED is compared to Planet Bike Superflash

Combine two, well, you get it.

To sort of repeat 10 Wheels question: What light do you have? I can see that it's a Nite Hawk...but what model is it? (Photo is not quite clear enough for me to see the numbers on the power pack.)

Looks pretty powerful, in any case.

It looks like a DIY dual cube or Nova Bull I think. I'm leaning more on DIY just by the looks of the silver alum and the button switch.

Yup, DIY. Details here. https://www.bikeforums.net/electronics-lighting-gadgets/440641-my-diy-taillight-version-2-a.html

Nice that you have a brighter light.
How much do you charge to make them for us, that do not have your electronic ability's?

Buy this instead.

HEE HAW here we go again. I like the Cateye LD600 because it's cheap, uses very little battery energy, and it's very bright from the rear, plus if mounted vertically can readily be seen from the sides whereas other tl's cannot.

I got my Mars 2.0 for $9.95 at Dick's Sporting Goods. They ony had 2 so I grapped both

I had both of these, I gave the LD600 away, the Mars 2.0 is sitting in a box full of other crappy lights.
The only lights I use is Planet Bike Superflash and my DIYs. Rest of the blinkies on the market sucks.

Anybody mount a PBSF on the '08 Madone? I don't think the PBSF will fit the new seat post design like it fits the standard round one.

The 2nd post said it all.

The seatstay mount might work, despite the triangular nature of the seatstays (use the rubber shims in three sections, perhaps).

I too bought the Superflash, BUT the Superflash only strong point is if it's seen directly from the rear, the more off axis you get the less light there is visible to it's completly gone. The LD600 may not be as intense when viewed directly but it continues to be bright all the way around to the side of the bike...something the Superflash fails at completly. I use the Superflash on the seattube and 2 LD600's on the stays.

But the poster wanted to use only 1 light thus in that regard all around performance for rear and side visiblity is cleary won by the LD600.

LD1100 FTW
Brightness approx same as PBSF.
Dual control so flashing and steady.
AA batteries so good runtime.
Side shinning LEDs
Batteries replaceable without taking light off bike, no tools needed.
Solid seatpost mount (but crappy belt mount).

Have these too...
Mars 2.0 need screwdrivers to replace batteries, short running aaa batteries(nice wide beam though). Big. Has rack mount which is nice.
LD600 rattle in holders and batteries you have to dig out. Again shortish runtimes as AAA batteries. Nice seatstay mounting as low profile.

Don't have these...
PBSF no side Viz. Small so good for helmet mount (ld100 smaller though).
Dinotte short runtimes funny seatpost mount $$$

I don't follow brightest=most safety. I think there is a point when all those super bright lights turn you into a distraction rather than another vehicle on the road. People tend to steer toward what they are looking at. If it's you with all that 'blink' then that's not a good thing.

After years of different setup I think the best balance is a ViewPoint on a blinking setting with a solid LED on second locale. I use a Knog on my messanger bike for this.

I recommend two tail lights that work really well.

The Planet Bike Superflash (PBSF), has these options going for it.

1. It is really bright for its being a small, battery-operated tail light.
2. It can be easily clipped or mounted anywhere on the rider, the bicycle or its bags/trunks/paniers.
3. It is lightweight.
4, It works for a long time on one set of batteries.
5. It is cheaper to buy but its quality is good.

The CatEye TL-1100 also has these going for it.

1. It, is large, bright and is more obvious.
2. It can be mounted to a rack, seatstay, or clipped to a bag or panier.
3. It is heavier.
4. It has more patterns and features than the Superflash.

You can't go wrong with either one. I bought three Superflashes and mounted two of them to the chainstays of my bicycle. I have the third one clipped to my helmet.

Dinotte in bright sun shine.

This is a very old posting, but in case you're reading, the current version of the Blackburn Mars taillight has a snap closure and no longer uses screws to hold the battery cover in place. It is quite bright from both the rear and sides and very well made, in spite of its low cost. The use of AAA batteries keeps the unit lightweight, yet I still get good battery life, in spite of using rechargeables. It comes with a variety of mounting options, including a neat rack mount that attaches to the reflector bracket of a rear rack. It also has a built-in belt clip, when all else fails. I've used these for years, along with several other styles, including the ridiculously overpriced CatEye LD1000. Although I wouldn't touch the rest of the Mars lighting series, the taillght is my favorite of all the blinkies.
