The brake light / cruise control switch is very slightly different on the XJ8 vs. the XK8 x308 Jaguars. The XJ8 one is LNB6420BB, and they cost close to $200. The XK8 one is LJB6420, and can be found for $30 on ebay. A very slight modification is necessary. The LJB one is removed from the larger metal bracket, and would fit but for the fact that the slotted tab at the top is slightly too narrow. The solution is either to take the old one and grind out the slot in the plastic on the new one to be identical (about 1/16 inch wider -- see photo) or to replace the electronics in the old one with those in the new one (they easily slide out from the plastic box). Yes, the harness on the LJB is too long, but it is the same plug, and can be zip-tied out of the way.

Replace the $200 Brake Light Switch in a XJ8 with a $30 XK8 one

 

I believe I've seen posts on here listing the part numbers to buy just the microswitches to rebuild the faulty one too.

 

Yes, replacing microswitch fixes the thing at minimum cost and job involved

 

Yes, the switch replacement works, but removing the through-hole 3-pin soldered in switches and replacing them requires some soldering skill and experience.

 

That reminds me, I keep meaning to find the info & order the switches. I've got a broken one on the shelf to try & fix as a spare.

 

omron D2HW-A211D does the job

Excellent, thanks. I'll order a couple for one boring winter evening.

 

Cool, got a 'no brake lights' - this should fix it, hoping it's not the SLMC!

 

Do you mean surface mount? No, they are through hole and quite large one so easy job
