Hello everyone. As an FYI, as I don’t post a lot, I’m sure most will think I’m a new member but that’s not the case as I’ve been a member for years. I spent time searching the forms and can't find any answers so I thought I see if the group can help. I have an aftermarket rearview camera that come on when you put the car in reverse, or I can manually turn it on with a button. It stopped working when I put the car in reverse, and I also noted my reverse light (I know there is only one on the RH side) is not working either, but the camera will work when I use the manual button so not suspecting the camera as the issue. I would think that the backup light not working wouldn’t cause this and there is no light warning/error message either so wondering if there is some sort of switch for the backup lights. I looked at the manual and there doesn't seem to be a fuse for the backup lights. Any help would be appreciated. I have a 2007 XKR base coup.

 

Remove the cover from the lamp assembly and see if there is power to the LED bulb. If there is power to the bulb inspect the wiring on the earth (ground) side with the gear lever in reverse. If there is a complete circuit, the bulb has probably failed.

 

Are you certain that your battery is fully charged? Many electrical gremlins are caused by a low battery.

Did the backup light turn on/off automatically when shifting into/out of reverse after the backup camera was installed? Did you do the BUC installation yourself?

 

I had a shop install it and it did work when it was first installed. I will test for power and ground and thanks for the suggestions!

 

I have power so it must be the light. anyone know the part number and a place to source one?

 

See NBCat's Post #2, above. I'd try a new LED bulb before replacing the taillight assembly that houses the backup light. Make sure you have a good ground.

You can check with the Forum Sponsors that sell parts, such as SNG Barratt, but I think you can probably source that bulb on Amazon or Ebay.

You can get the part number by removing your existing bulb. The part number should be on that bulb.

 

Thanks everyone, but when I took the backup light housing off, it didn't look like you couldn't change the bulb. It looks like it's alll one peice and a circuit board with LED's as part of the the assembly. I've owned 5 Jaurar's and dispite having the motor blow in my 2011 XJL and my 2012 XJ Supercharged, I keep buying them (maybe a different story if they wern't under warrenty lol) and I have to say this is so frustrating that something that should be really simple is such a PIA. They should make the designers and engineers work on them and I bet it would be easier to do maintenance on these cars. Why would they design a $90k car without oil dipstick? Some days I miss old school cars that had simple things like bulbs you could take out and replace without having to take apart half ot the car

 

Your 4.2L 2007 XKR has a conventional engine oil dipstick.

I haven't disassembled the taillights, but I'll take NBCat's word that it has an LED bulb because he's Tech Certified.

 

.... but they ARE LEDs!!! The outside actual TAIL lights have regular old incandescent bulbs, but the inners, Reverse and Fog lights are LED units.

2007 Reverse Light Assembly:

 

Thanks again and I was talking about the new Jags that don't have dip sticks lol

 

My 'new' Jag without a dipstick has the same LED lights for Fog and Reverse. Slightly different design but still.

 

NBCat threw me off because his Post #2, above, contradicts his earlier post on 02-25-2018, screenshot below.

NBCat's Post #2, above, 09-24-2022:
Emphasis mine. This is incorrect. There is no LED bulb.

The information below is correct.

Sorry for the confusion. Cee Jay's Post #9, above, is right. The backup light assembly must be replaced, if the power and ground are good.

P.S. RH inner tail lights are available on Ebay. Get a written guarantee that all the LEDs in the backup light work. See: $210.00. and $228.80

 

Not sure how these work - could be an option:

Thanks everyone, one last question, I can't seem to find a fuse that is for the backup lights and all other lights on the car work. Anyone know the location? Other than that, I think I have all the necessary information to get this fixed or replaced and will let everyone know the out come.

 

You have not followed the conversation. The reverse and fog lights are one-piece integrated LED units.

 

Yis I have lol - that link is claiming a replacement. Not sure if it's a valid replacement. If it was me I'd rip the thing apart and see what kind of LED's
are used. Most likely surface mount. But looking at this XJ/F replacement board there are a few more parts on there. Remember when you replaced
the diode on your brake light? These non repairable items can be repaired if a person has some soldering skills.

 

What you state has already been done on a different very recent posting. Dude took a few weeks, trial and error, and made replacements for individual diodes and such and now has working units.
Here's his recap:

Missed that thread - working with surface mount stuff is a bit tricky - you do need some strong magnification and a steady hand with
the soldering iron.

 

I can't solder worth a crap so won't be trying that at hoime. Need to trace the backup camera wiring to see if it's causing the issue. Going to dissconnect it and see if it changes anything. This is really a great fourm, not sure if Ia've ever see a post that someone didn't take the time to respond.

 

First of all, it took a fair amount of research to ascertain that the '09 XKR trunk lid has (1) bright fog *red* tail lamp, one (1) bright white LED reverse lamp.

A strange configuration to say the least.

In trying to wire a back-up video camera mounted on the license plate frame, the camera power + lead gets mounted to the bank-up light wire, so the camera comes on when the car is placed in reverse.

However, as typical on a Jag, nothing works as its supposed to, and the light comes on, but will go off intermittently.... ergo, so does power, and the camera.

Is this design as intended, or is the back-up light and power malfunctioning?
