In stalled these in my 2000 c5 vette. The chip that's in the led bulb did not seem to be positioned at the 3 & 9 o'clock position. Also had to aim both light housing. this is somewhat a choir. Had to remove passenger side light assy. due to frozen up adjustment up & down rod. Overall light out put from low beams Led 9006 are way better the best halogen bulbs I purchased.
The lights are very bright and easy to install. They have a good white color not bluish at all. However they tend to illuminate High, I'm concerned that I'm blinding oncoming drivers.
