absolutely love my cup spoiler but they do come with one huge downside: they're bonded on so if an led goes out on the third brake light you're in trouble!
there's no way to access the screws that hold it in and of course a few months ago one of the leds in mine went and the reality of fixing it took a lot of time, worry and research. everyone said don't bother but i wanted it sorted and mint again, and another could blow and then it'd be a laughing point rather than a feature. had to be done.
so here's my how to on replacing the third brake light on an oem cup spoiler... the hard way:
part 1.
1. prep everything - tools out, double check you have everything you may need, cos once it's out you can't drive it anywhere till it's fixed... hmm. mask off around the spoiler
2. using a dremel, CAREFULLY drill round the edge of the red lens to get to the led rack behind. don't go too near the edges or corners - yet.
3. concentrate on once side at a time, chip out the led rack
4. the screws that hold the light in place are on the far edges. these have to be cut out. don't drop them inside the spoiler!
5. wiggle the light past the clip in the middle on the top holding it in. cut off the light from the cable, leaving as much cable free as possible.
6. walk away, make a cup of tea, the difficult bit's over!
