I'm thinkin about putting them on my bike for some side visibility.

Does anybody know how long they'd last w/ a 12v 1.3AH battery???
I should know this but... nope.

Not sure about legality. Most codes specify white light or reflector for the front of the bike and red light or reflector for the rear. Never seen anything mentioning side lighting for a bicycle.

That being said, it looks like overkill, extra weight, and complications. How about a couple of Planet Bike Superflash lights mounted sideways?

Side visibility really isn't that big of an issue as far as I'm concerned. If I was worried about it, I would get some monkeylectric or a down low glow. There are other POV lights similar to the monkeylectric. There are also spoke lights. Spoke reflectors are actually fairly effective. Lots of good options before you get away from bicycle specific lighting.

12V @ 1.3 A-hr would be 16 W-hr. That site says the lights are about 5W, so based on that you should be good for about 16/5 or 3 hours. But it's not clear if the "4 - 6 Watts" is the average power or the peak power when flashing. If it's the latter then they'd last many times longer - how many depends on the duty cycle of the flashes.

I am not sure how much "over-doing" lighting and reflectors actually help. If you are already lit up, the people that hit you are either drunk or not paying attention.

We had a local guy here lit up like a Christmast tree - really. Reflectors and lights everywhere. A drunk hit him and dranged the bicyclist under his car for a quarter mile.
