I just replaced the fog light assembly on my 02 burban. Now when I roll over bumps and pot holes, I can see the light shaking. I couldn't tell if it was shaking before because I had the 27 watt bulbs in. Now I have hid's installed I see the light shaking. I need some ideas to fix this problem. Thanks for your help.

 

it's probably just the mounting bracket. not necessarily broken, just the way it is. my 04 pickup does the same thing. lightweight plastic mount doesn't take to bumps too well. might be able to fab up some sort of stabilizer, or better, stiffer mounting brackets.

 

I take it you're not using them for driving in fog as using HIDs kind of defeats the purpose.

 

73Shark - Just wanted to say that the Tahoe comes stock with white lights in the fog lamps. White is not for fog, it's for driving. Which is why they are also called driving lights.
