Hi all!

Has anyone come up with a bullet-proof way of mounting the hi-mount brake light. Mine fell off today (about 8 months after I repaired it) I did not use an epoxy as it was more like a thick-bodied contact cement, from Permatex, I believe. I painstakingly cleaned and prepped the surface and thought i had hit a homerun... it was just a ground-rule double I guess.

But anyways, if someone has a solid remedy I would sure appreciate hearing about it.

Thanks,

Bucky

 

use a two part epoxy, hysol's what I used on my XJ6L and XJS, no problems even in the hot FL sun.

 

All you need is a $6 tube of DAP Auto/Marine Sealant 100% RTV Silicone. Clean the window and light bracket good with denatured alcohol and let dry. Dab a drop of silicone on each of the two bracket bosses and attach to window. I kept the brake light on the bracket during the process, others do not. Have a prop ready to support the light against the window for 12 hours and immediately support the light after making contact with the window. I used a folded foil front window sun screen and it worked perfectly.

My 3rd brake light has been up for about a year has survived the Florida sun and heat. Heat is the big reason the glue fails on reinstalled upper brake lights. Most glues can't take the heat. This silicone product is unaffected by temperature extremes (-40F to 400F), and it's also a little flexible which helps the adhesive stay attached where other hard contacts might break.

 

after a few trs at bonding i removed the speaker deck and made a steel bracket
