Future motorcycle brake lights

[Monkeyman]

What kind of power would those lasers draw? Most of them seem to be battery powered. I don't think I'd want the hassle or expense of having to change batteries every few days. I think that would work well assuming you could 1) hang it off the back of the bike and 2) get a wide enough pattern. At night, it would at least get someones attention. That's a start.

These are battery powered since they're for a bicycle, but even at that they are rechargeable with what one of them called a "cell phone" charger. That's only 3-5 volts generally. If it ever shows up for motorcycles or cars it would be hardwired I presume. I was imagining something that would mount under the tip of the rear fender. ??? But then the lane projection beams would be aimed much more toward horizontal (to project wide enough), and where they project would be much more affected by lean angle of the bike or the lay of the terrain you're driving on. Whereas a bicycle rarely leans far, especially a commuter, not a racer
But now I'm getting technical over a day-dream
