Since then I switched to Piaa LP530 leds and have had zero issues. They are also backed by a 2 year warranty, if it breaks Piaa will replace it. Besides reliability, the other nice thing about these that the leds are aimed backward into the multidirectional reflector, producing a precisely focused beam that can be aimed so it doesn't dazzle oncoming traffic, unlike most LED lights. $209 complete with a Piaa harness at Amazon. http://www.amazon.com/PIAA-5372-530-...sim_sbs_auto_2
What happened to them? I have a set I just mounted, and am now a bit concerned.
