Confirmed fix
Ok folks..I have a 2000 s-type when I turn on the right turn signal the rear bulb and both reverse lights flash real dim and slow??? I also noticed while looking around back there that someone has run a jumper from the right tail light to the left. Unhooked that and it didn't change anything other than the right brake light going out ...so I put it back lol...any suggestions? Thanks
So this was a two part solution but mine was doing the same exact thing
So how it happened first. When I went to the store to replace the turn signal bulb I pulled the board, got the bulb, and just placed the board down (still connected electrically, dumb I know) when I went to pick the board up it made contact with the trunk and I heard a pop. The board short circuited. If the brake light is out on that side then you probably need to do both things I did. If not skip to step 2
SOLUTION:
1 replace board. I got one for about $50 on Ebay. Confirm brake/tail light now works but turn signal will still likely cause 3 total lights to blink dimly
2.) ReplaceRthe 10a fuse f44 located in the trunk compartment just in front of the battery
This is on a 2003 jaguar s type 3.0L

Wiring diagrams for your car are here:
JagRepair.com - Jaguar Repair Information Resource
Open the PDF for your year and scroll down to Section 8.2.
Unless you have damaged wiring, the most likely culprit is the Rear Electronic Control Module.
Please note the control of the exterior lighting is different than on most vehicles. Jag uses a constant power supply to the bulbs, and the control module switches them on and off through individual grounds. The taillight assembly is completely insulated from the chassis.
On most other vehicles, the bulbs all have constant grounds to the chassis, and power supply is switched on and off. With that system, the loss of a common ground (between the taillight assembly and chassis) can cause all sorts of strange behavior, with other bulbs lighting up at half brightness, etc.
If you had your same symptoms on a non-Jag system, I'd almost certainly say you lost a common ground somewhere, but that's not going to be the case for any of our Jags. Unfortunately, I think that Rear Electronic Control Module is at fault.
