And very easy to see that they work. They don't have to be bright. You have GOT to be kidding me that you think that a 500 lumen flasher in broad daylight will blind a driver. I've put my bike on the side of the road and approached it in a car as a test, and it's not irritating at all. It's obvious but it doesn't obstruct vision, not even a tiny, tiny bit.

Also, there's no such thing as a MUP around here. I ride 100% of the time on roads. My lights are not as bright as car headlights.

I run a 500 lumen flasher during the day and have had many people see me on the roads and have gotten nothing but compliments from them.

Before I started running a front flasher, I was running steady front. Stuff like this:

happened to me about once every 6 weeks or so. After it happened twice in 3 weeks, I started running strobe mode.

It's been 3 years since then and not one car has done that to me since. I have seen cars start to pull out to pass, then pull back in again.

Sorry, but if it's a choice between being slightly irritating (I'm not convinced it's even that) and getting into situations like that, I'm gonna blink.

A woman was killed a few weeks ago on a road I ride regularly, same situation. Head on with an oncoming car passing another car, driver didn't see her.
