Hi. I want to change my tail lights on my 01 Jaguar S-Type but I don't know how... Any help?

 

Do a search on the forum. I strongly suggest getting a service manual. In a nutshell, you will need to pull the trunk lining. The rear part of the tail light holds the bulbs and can be pulled from the lens once the lining is out. It should be pretty straight forward.

 

Be careful not to cause any electrical shorts as you work on it. It'll likely be LIVE.
