I've put H11 LEDs in my low and fog lights. Incredible upgrade using the Lasfit brand from Amazon in the fogs. Really bright. The low beams were my first upgrade and like another on here I went with a 35w, 5400L bulb. It has a great beam pattern (which is adjustable with a collar) and meets local laws on brightness. I've heard of a lot of folks getting flashed or road raged due to brightness being too high. The fogs are another matter, I went big. They are so low and aimed right at the road and tend not to bother anyone. Plus, if I was asked if they were legal, etc., I can just shut them off until I find out. So far, no issues.

I stayed stock halogen in the High Beams though. When paired with the Lows its still a ton of light.

I'd like to put 9005 Leds in, but am wondering if anyone has had the flickering issue in this year (2011) SR5 model that doesn't use the high beam as a DRL? My DRLs are orange, and are low bumper mounted next to the fog lights.

Thanks for any help that can be offered with that question.
