One of our Adaptive Xenon lights is completely unresponsive and pointing straight down in a very sad fashion. New units are over £750 and good used ones are well over £100. This guide will show you how to strip the headlight housing apart, identify all the working elemets and fit a new motor to fix the headlight assembly. The motor isn’t available from Land Rover but after a quick google we found a new part to do the job.

Don’t forget if you are going to use a high rpm buffer to clean the lenses you will need to use plenty of water as it will create a lot of heat.
Disco 3 eBay link?
I did a set of headlights using a similar kit and a cordless drill – the headlights were still in the car, so I could apply more pressure. Took about 30 mins each side with multiple grades of abrasive (finished with 2000 grit) and kept the headlights wet throughout. Finished with compound and a bit of polish.
I have a adaptive xenon’s on my Disco 3 and they are superb, best headlights on any car I have ever known. Perfect on dark lanes. Deffo get a polisher, I used on on the headlines on my Project/Beater Audi A2 and it was perfect after a bit of sanding with wet and dry.
Diet looks like its working well.
You did very well on that one, I suppose you could not fail really as you would have to buy a new H/lamp any way, I find it worrying that just the headlamp is more complicated to work on than a complete strip down of a 1960s engine! Chris B.
