This 05 Blazer I picked up last week came with a set of Glare LED headlights installed in it.. appear to be the XL Series headlight kit. They're very blue.. which I'm not terribly fond of. And the name 'Glare' is rather appropriate as they throw light pretty much everywhere, though surprisingly I haven't had a single person flash me their high beams yet.. (maybe because I've blinded them? And they can't find the switch...?)

But I'm having an issue.. the passenger side one is flickering. I'm guessing it's getting heat soaked, because it doesn't happen when it's cold out or when I'm driving. It's when I come to a stop or am sitting at lights, that I notice it start flickering.

I've checked the connections, they're all clean and tight. Haven't tried swapping bulbs/ballasts from side to side to see if it moves.. but that's my next step. Perhaps tonight if the rain holds off.

Anyone tried these things yet? I'm looking for ideas to stop the flickering. Yes, I did email them, waiting for a response. They're local to me, so hopefully they can swap out a ballast if that's the issue.

 

Is the fan running or making noise? 32W (if that's anywhere near what those actually can pull) is a hell of a lot of power to dissipate passively. Make sure the fan runs, and maybe see if you can read a temp on it when you notice it doing that. LEDs are very sensitive to higher heat levels. If they get too hot, they will color shift to more blueish (even purpleish) and will get dimmer until failure. If they are not color shifting, you may have a balast issue. Shouldn't be too hard to differentiate between the colors of your two lights.

In the event they are shifting, 100*C (212*F) is the most I've ever seen an led run at any length of time without damage. I honestly would go back to regular halogens if you don't like them anyway.
