The high-mounted stop light on my KH Verada fell off. The mounting clips had previously been stuck to the window with araldite, a fair bit of which is still stuck to the glass.
How are these clips supposed to be attached to the glass and at what position? I can't see anything in the manual and the handbook says take it to a dealer.

I would think an automotive glazier could have a solution. I'd expect it to be glued similar to the rear view mirror. could be a 2 part primer/adhesive specialised for the job

We used to use sikaflex and use rolled up paper to hold it up in place whilst it dried

Don't just glue the clips back on, as they won't align with the mounting holes in the actual tail light.
I used some black windscreen glue - sikaflex - covered the appropriate bits, placed the whole thing back where it is supposed to be, then propped it up with an empty soft drink bottle and left it for a while. Looked real Ghetto Cool driving around like that.
Hasn't fallen off years later, drooped a bit, but I'm not touching it until it does fall off again.

Thanks for the info.
The araldite had got everywhere and stuck the clips to the light but with a dremel and a bit of luck I restored everything. I re-installed the light with double-sided tape until I found what to use. (I don't really expect it to stay there!) It looks like Sikaflex is the way to go. Thanks for your help.

I imagine in production a jig of some kind is used. My lamp has also fallen off on the passenger side. I'm not sure what the adhesive is.
What I did was to use a contact adhesive because there was adhesive still stuck to the glass.
The clip showed evidence of the adhesive softening, judging by the way the glue had formed into stalactites. I removed the major roughness from the clip with a blade. Then I applied the adhesive to the clip which was fitted to the lamp and pushed it back to the rear window. Then I removed the lamp assembly, removed the clip, and restuck the clip to the window. The tolerance of the clip width and the slot in the lamp holder allows some slight misalignment.

Where the clip fixes to the window, the window is treated. I guess Sikaflex is Ok to use because it is a one part polyurethane cross linking material. A lot of polyurethane is used for glass fixing and other uses in modern cars. I would have thought Araldite was not the best material to use because it becomes fairly inelastic when it cures.

Hope this helps.

BTW, Supercheap sells tubes of this stuff called "Dynagrip" which is used to bond rear-view mirrors to windscreens but it can also bond other materials to glass as well.

Best to use the Permatex Black Silicone. Mine fell off just after 5 years from new and the Permatex fix stayed even when it was parked under the sun on most days. It was still firm when I traded it in this year. The following was what I did:
1. Put the tags on the window where they are meant to go (like on the existing poor job of clear silicone and you should be able to do that as well before removing the araldite on the window).
2. Stick masking tape on the four sides marking the spot.
3. Remove the exising glue.
4. Put a decent amount of Permatex Black Silicon on the tab and put on the window within the masking tape area and use a piece of broom handle (cut short) etc to prop it up and tape with masking tape so it does not slide around.
5. Leave it for 48 hours and then attach the brake light to the tags.


If you have already removed the existing araldite then do the following:
1. Fit the tags onto the light and slot into position.
2. Stick masking tape around the bottom and sides of the light unit to mark its position.
3. Remove the light and then apply the Permatex Black Silicon on the tags and re-fit the light unit as a whole.
4. Prop up with a broom handle and tape in position and then leave for 48 hours.


Finally, do not bother taking it to a dealer. They will just tell you that you need the whole rear windscreen replaced.
