I cannot find anything to stick my eyelevel brake light to the rear window of my renault 1.4 megan (it falls off after a day or 2) what will glue it on & KEEP IT ON many thanks in advance.
Halford sell a roll of double sided tape. It is black and weather proof. I have used it for years to fit number plates instead of screws. I think it is made by Bostik/Evo erm! one of them anyway. There may be two types, black or white, you need the black one as it is made for outdoors.
