I have had mine in for a couple weeks now and hadn't ridden at night until just now. It def does a good job. As for as durability IDK. If it went out as whole that would suck but I believe it has like 5 or so leds in it so if just one went out you could def make it. It was a perfect fit, only trimmed the rubber gasket because it was stretched and deformed. Yea I seen those blinkers the other day someone put up with the white lights, they look cool.
