They weren't expensive so can't really complain. But they are advertised as 18 watt LEDs (6x3) each and there is no way they are 3 watts each. They are nowhere near as bright as the other flashes on my ambulance, all 3W linear flashes. You have a good idea, just not the best execution. If you use them, they are best mounted on the rear bumper or fender, as well as an additional side flash. Don't rely on them as main signal lights! **UPDATE 11/02/2018. They didn't even last 6 months and 3 of the 8 I bought have burned out. Don't waste your time or money. I'm moving on to Phoenix and I'm done with that. I wouldn't even put them on my baby power bikes!
