Like many others here, I upgraded to the LED DriveBright DRL/Signal lights. Like everyone else, they flickered after install, requiring a replacement to an upgraded control box. Well, I did that and now they flicker again. I only replaced the box about 2 months ago. Funny thing is, they don't flicker with every turn signal flash, but it's sporadic...sometimes two flickers in a row, then two normal, then one flicker then 3 normal, etc. Anyone else have this recurring issue?
