This kit contains the two plastic headlight adjuster mountings which often break within the E39's headlights. BMW do not sell these parts separately and you would be required to buy a complete headlight. This kit enables you to repair the lights and save a lot of money.
When these adjusters are broken the headlights bounce and often point downwards resulting in poor visibility at night. It is a very common fault and an MOT failure.
This kit includes the two parts shown in the photo and is enough to repair one headlight.
We also sell the adjuster mountings for the earlier E39 (1996-2000) headlights.
