Having been around here for many years there have been a few that have had issues with the panacea LEDS. I know there are plenty who have not had issues as well, but I thought i would throw that out there.

I love Kuryakyn's panacea taillight. That being said, I have gone through 3 of them. Blown LEDs or random blinking, even Kuryakyn reps cant seem to find the problem (had them work on it at OC Bike week last year), they keep replacing them for no cost, so i cant complain, but i will be changing this year to just an LED taillight. Turn signals are overrated!
Have gone through two Kury led rear tail lights. Second one was after the warranty period. Highly recommend Custom Dynamics LED products as they are extremely bright with lifetime warranty. Radiantz gets good reviews also.
