update - thanks everyone for all the good ideas. Much appreciated. :-)
So I think i like the idea of 3M VHB tape - 2 strips of 3/4” - to simply VHB tape the auxiliary brake lights to the *top* of the 1.5” strut… and the base of the brake lights are flat…. so this should work out well.
It is cold (freezing and below) where I currently am…. so I’ll have to wait a bit to install… a quick internet search indicates that VHB tape won’t adhere properly around freezing…..
I guess I could use a hair drier to first warm up the metal… but I’d be afraid that it would cool off too fast, and not bond as well as if it was warmer…..
Here is the 3/4” 3M VHB tape I’d likely buy…… sold from actual Amazon, so less likely to be a cheap fake (that 3rd party sellers sometimes sell on Amazon)
