My newly acquired 1986 XJ6 failed inspection for a faulty headlamp relay. Part number: 4rd001836-05. I’ve searched a few vendors and haven’t been able to locate a replacement. Are there any universal fitment options which would work? Recommended parts suppliers to search? Any and all input would be greatly appreciated. Thank you!

 

Give David at Everyday XJ a shout. He breaks up unwanted XJs for parts and he probably will have one. He's a helpful guy and his parts are reasonably priced.

No affiliation, just a repeat customer.

 

Yup, David probably has a box full of 'em !

Or Google "Jaguar C38616"

Cheers
