I got my interior lights rigged up . I used that 3M double sided tape , it seems pretty sticky . We'll see how it does with temperature change and rough roads...
I have these lights for my undercabinet lighting in the kitchen. Where the stock "peel off the back" wasn't sticking so good, I added a little bit of contact cement with a Q-tip applicator. Wait a minute and press on. Works like a champ.
