I have had these stonegards on my 00 L for about a year now with no problem. I upgraded to the Piaa H3,s 55 watt bulbs. And with in an hour there are big brown spots on the center of the fogs. Any one else have this problem. And does anyone have a solution. I can tell you these bulbs are hotter than the stock bulbs. Wich are 55 watts also. Thanks. Bob.

 

I only ever had my StonGuards with ultra-white lights, and they burned them.

They run hotter then stock due to the color index...guess we won't be able to use stoneguard.
