Not many day but when they do, it’s flash

Rear primarily flash as well, day or night.

No you don't do that. Yelling fire in a crowded theater is not the way you stand out. Get a good light with a good beam pattern and keep it solid or just avoid riding. It is not hard. Having spent a lot of time riding in dense busy lit up places I can say I have never once needed to flash a light to be seen.

If everyone else jumps off a cliff because they saw someone else doing it, would you join in?

Flashing at the rear isn't so bad as it is a red light which is less damaging to the eyes. However a solid light ensures best visibility at all times.

There a father around here who I see on the main bike path walking beside his little girl who is learning to ride.
She has two very intense white flashing lights mounted to the front of her tiny bike.
I can sort of understand the father's idea, but I can't see a thing as I pass by. It's painful.

Double yawn

Pics or it didn't happen.

You don't want to die on this hill VB. I don't flash my front lights because I need them to see, not to be seen. However, I don't know of the front light made that doesn't have a flash mode! Above my pay grade why, but you can't tell (in all caps) people who have spent good money buying name brand lights that they 'can't' do a particular thing with them for which they were designed to do. Encountering (head on) a 1200L headlight is going to hurt whether it flashes or not. I don't ride MUP's so I don't ever encounter bright bike lights coming at me at close quarters but, as a commuter cyclist, I encounter plenty of HID automotive lights, many in the 6,000L range, and I survive. And, given the realities of modern life, I encounter more high power car headlights per hour than any cyclist confronts flashing front lights in a month. Hold your line and look away is what they teach drivers.

The side mount light worked, but based on my testing in a darkened room, it did somewhat reduce its efficiency, especially with a jacket stuffed in the bag.

The light I ordered is from Amazon so easy to return if it does not provide an acceptable solution.

The bag might be secure, but the top of that bag is not a secure platform for a light. And you don't even have the light yet ... how typical.

Why the heck would she need two flashing lights if he's walking beside her ???

I have a B&M Luxos U on two of my bikes and a B&M IQ-XS on two other bikes. Those four lights do not have a flash option. At this time I do not have any other front white lights on any of my bikes. But over the years I had some AA or C cell powered lights that did not flash either.

Take a look at some SKS raceblades for one way to do it.

I will die on that hill guns blazing! Literally it is dangerous, I had some bozo go past me on a sidewalk the opposite direction (I was in the bike lane going the correct way) and he was flashing a light and my right eye doesn't close the same way as my left eye so my vision was not good for a few blocks. NOT SAFE NOT OK. Sure they put in a flash mode that doesn't mean you need to use it or doesn't make it right. People sell dangerous products all the time, it doesn't make it OK it just is something that people do because they can. Companies put features into products they can sell and so long as nobody stops them they will keep doing. They can make money and that is always going to be their end goal.

When it comes to safety I prefer not dying but if I have to die on the hill to promote safety I will do it. I am tired of people riding at my in an unsafe manner because they are selfish. I am not going to give it any B.S. it is pure selfishness. There is never a reason to flash a light unless you are an emergency vehicle traveling at high speeds. Safety should be for everyone not just you (general) because you (general) are special. There is reason why no other road going vehicles use flashing lights and why in most places it is banned for motorcycles. It is simply just not safe. I say it each and every time because it is 100% true I close one eye and look away from the road or path which is DANGEROUS if someone is flashing a light at me. I have known some folks who actually can have seizures and there is no way you can say well I should give some a seizure to make myself feel safe and there is no way in hell you could say "oh that just won't happen" you don't know who you will encounter who could be prone to it or maybe someone sees your flashing light and drive into you.

There is literally nothing you will do to convince me that flashing white light is safe. If I have to do something unsafe because of flashing white lights there is ZERO safety. If you really need a flashing white light point it directly at your own eyes and there you go you can have all the flashing you want and you get to enjoy it and fewer people have to be bothered by it. Again the you is general here.

I mean, yeah, if you work hard enough, you can find exceptions to every rule. B&M are the default in a market (Germany) where flashing lights are verboten. And why? Because German lighting infrastructure is exemplary and also the laws concerning vulnerable road users are quite robust. In America, not so much. Drivers are so apt to say "I didn't see him/her!" regardless of how much lighting firepower a cyclist brings to the party that all manner of flash patterns are programmed into American market headlights to enhance visibility. I can't speak to what goes on the trails. I know though that when I have driven at night in rural areas I am scrupulous about dipping my lights when necessary. Most drivers are likewise conscientious but as we know, not everyone. Why would MUP's be different?

So why are you here Mike? For someone to be so critical of a space, it doesn’t make sense to visit that place as frequently as you do. Maybe take some time to sit back and feflect on why you need to come here at all, because it’s starting to look like … trolling.
