My third brake light (or high mounted stop lamp) has a bulb out and also a crack in the housing. The whole assembly is sitting on a piece of foam at least and is doing most of it's job. Two things here... #1 I know that if I were to even attemp to change out a bulb I would replace all of them with the correct ones but, the whole thing will dissentigrate in my hands. #2 I'm going to purchase a new third brake light assembly from a supplier. (Thank God new ones are even available!!) I noticed that I have no mounting tabs on the back glass or on my current third brake light assembly. I know this car has sustained damage when it was in Miami during the early onset from hurricane Katrina back in 05' so I believe the rear glass was replaced with a new one but never had the mounting tabs installed??
So I'm wondering if new mounting tabs are even available? I looked in jaguars parts catalog and didn't see any unless they are under some other part of the catalog. Can anyone give me a bit of advice on this or a mounting tab part number would be great. Thanks for any help.

 

I'm also interested in this as I have a piece of cloth wedged under my third brake light holding it in position

 

Take a look on ebay for some of the used ones for sale. The mounting tabs are on the base of the light assembly and are fitted to the rear package tray. the face of the lens against the glass should just have a couple of rubber vibration points. It doesn't mount to the glass. It just rests against it. It mounts to the package tray.

 

Mine fitted to the glass! Needed epoxy to hold them in place in order to mount the lamp. Plastic on the lamp crumbled in my hand.

 

I actually went out to our parts car which was a 99' VP and it had one mounting tab still on the glass even though the lamp assembly was gone. I heated up the glass from the outside and scrapped off the mounting tab from inside the car. I was surprised to find this tab to be made from some type of aluminum or other nonmagnetic metal. Anyways, I'll try and hunt one more down before attempting the epoxy setup. Hopefully I'll get it mounted straight or I'm gonna be a little upset.

Jaguar issued a TSB 16 years ago for the loose CHMSL.

TSB 417-03

Yes I'm looking for mounting tabs as well. Or heck even a low cost better option for the third brake light. Currently it's just sitting on the sill with a pillow keeping it in place. I don't know how they sourced plastic this crummy.
