Weird 3rd Brake Light Question

[Unobtanium-inc]

I am eliminating the ET light from my '87 Carrera so I bought a glass mount factory 3rd Brake Light. It's new. I run the wiring, add a fancy extra plug so I can remove it and put in an LED version later if I decide to, measure, mark, measure again. Finally ready to stick the mounting frame on, but when I peel off the layer to expose the double-sided tape, it's white? The tape is white, not black. Did I miss something? Why would they use white tape, ever?
Help me solve this mystery. Now I have to find some black tape, cut it perfectly (a huge challenge for me) and add it to the light. Ugh. -- Matt

That's what happens when the lowest bidder gets the contract to make parts. I want to bet the light is made by Valeo.

It is my understanding that the rear glass that those lights were intended to attach to had the black area on the glass, so the color of the adhesive was irrelevant.

Here's the mount. The casting date was '85.

3M makes a dark gray almost black exterior molding mount tape. Usually available at autoparts stores.

It's very durable and thinner than many of the tapes available at hardware stores.

I recently purchased a new rear window (with 3rd brake light) for my '74. The window I bought is for an '76 and it has black tint around the area where the 3rd brake light is mounted.

Naturally, I put the window in the closet for a future project and it's been there for 2 years

I stand corrected. Did not think about the blacked out area.

+1 on the 3M tape. I used it to attach my third brake light.

Very strong stuff, and the adhesive lasts.

However, I was able to get a black version from an auto windshield replacement shop.

Didn't know about the blacked out area!

I would use black velcro.....glue one side the window one side to the fixture.....
