I would like to know The possibility of LED bulbs for all back lights and instrument cluster on an 87 XJSC? It would make a huge difference. Has anyone done that replacement?
i will check with my XJS friends in the club and post when I have answers
I believe little British Car Co or lbcarco.com has a kit for the XJS conversion to LEDs in america. Head lights rear lights side lights etc. under 100 dollars for the kit. Published in Classic Motor Sports magazine an article about the process, September issue.
