I've been swimming in it again trying to find a pair of 10,000 lumen 6000k LED headlight bulbs that will fit the stock reflector housing on a 2007 Tahoe, (and not hit the vertical frame member behind it with big bulky heat sinks and cooling fans, like the pair I'm sending back to Amazon right now). Trying to find a pair that the LED's are in the same exact position and orientation as the standard halogens, so that it will work with the factory reflector and not blind oncoming drivers. Also looking for high ratings. If anyone has done this upgrade and had good luck with their LED headlights, please sound off. :v
