Third break light
 

My third break light keeps coming off, the sticky pads on the feet seem to have lost their stick.

What bonding is best to stick them to the screen?

Gabi,

A good quality "super-glue" will work, but as it's a sloped surface, I suggest buying the product in a gel form. It should be readily available at any industrial supply house. Permatex # 82191, comes in a 2 gram tube.
The gel will keep it from running down the window and making a mess.

Outline the spots to glue with some masking or duct tape, then clean the surface well with rubbing alcohol. Apply the gel type super-glue sparingly. A little goes a long way.

Make sure to clean off the old adhesive pads and make sure the underneath of the mounting pad is super clean.

Tape the mounting pad down for an hour and it will be as good as new.
