Yes, because it was made "legal." It was illegal previously!

Sorry, I misread it- I blame lack of sleep due to a newborn

I run a lower output blinking mode in the early morning hours mostly on empty MUPs riding 25 miles into work (which I don't do that often). My light will run for many hours in that mode. When I get on the road I set it as powerful as a car's low beam and steady; running in blinking mode is to save the battery for when I really need it on the road.

egzachary!

Generally a bad idea but there's a time and place for flashing white lights on the front. Think urban settings where there are lights/glare everywhere, so a little bit of call to attention is good. Or in parking lots, on sidewalks, or other areas with a lot of pedestrian traffic.

excellent! congratulations! best wishes for every time you think "I've got this" something changes ... hehe but seriously, well done you & whoever?!

If I recall my neurocognitive stuff correctly, a strobing light is better at attracting attention rather than a fixed beam. That is why some higher end cars will initially have flashing brake lights to get your attention. Also, police cars, ambulances, fire trucks will have strobing lights, even road barriers will have strobes on them to attract your attention. That is one concern for these emergency vehicles stopped on the road at night, drivers will actually get distracted and drive TOWARDS the strobing light which is why you hear about stopped cruisers getting hit!!

As a driver - I just don't care what light you have on. For the love of life, just have something one light on, reflector, light coloured clothing so I can see you in the dark. I've come close to hitting people are riding in the dark or in the rain with no identifiers on and I've braked/swerved at the last second to avoid impact. Folks say, but the car has headlights! But if they come up from behind me and are in my blind spot when I make a turn, they are as good as dead.

That being said, rear lights should also be strobing so drivers from behind can see you, and fingers crossed, not drive into you. Red is best for the driver's night vision, but quite frankly anything is better than nothing. Front lights should be both types, one super bright and fixed for your own vision, and one dimmer that is strobing so oncoming cars can see you. Usually white is the default for the front so the drivers can figure out which direction you are going.

That's what I've found.

I have relatively poor vision at night. Corrected, so focus is pretty good, but like most people it suffers somewhat in the dark, even worse if misty, foggy, drizzling. But I've noticed I can visually pick up cyclists much more quickly if their lighting is more attention-getting. And that means flashing some sort of pattern, other than strictly steady.

As some have suggested, multiple lights where the light pattern differs (ie, one stead, one slowly/randomly flashing) can draw attention where a single light can get lost in the visual clutter.

Myself, I run two red taillights, each flashing a slightly different pattern. Crazy bright, separated enough to be clear, and flashing to grab attention as early as possible. I run a single headlight most of the time, and it's on steady during runs in the dark, but I do a crazy-bright flash during the daylight hours. Riding as frequently as I do on narrow two-lane streets (without shoulders, with ditches), it's important to gain attention as early as possible in such places. I notice drivers drive a bit more gingerly when I've got the "aggressive" flashing modes on, yielding a bit more space around me as they blow by.

I run my front light in blinky mode, but its not that bright and its pointed down towards the road about 10 yards in front of me. The neighborhoods I ride in after dark have great street lighting, so no real need to run anything that's as bright as an aircraft's landing lights.

That said, what someone said above about the off-street MUPs in my area after dark is true. No lights on the MUPs but bicycle riders seem to want to run the brightest lights they can find and point the light straight ahead. I'll sometimes start just before dawn and those coming towards me almost blind my vision. Geez, if you're going to ride on the MUP adjust the light down toward the asphalt path surface where the hazards might be, I know I can see you're dimmed light and you can see mine.
