Another option to consider might be the Oznium LED modules They do not screw in though, rather set with VHB tape. Clean the area really good, and right before setting give it a final wipe with Isopropyl Alcohol, let that dry then apply the light module, use one of the ratcheting clamps to give it a good squeeze to set the VHB and it wont fall off. https://www.oznium.com/led-string-modules/super-bright-12v-led-module
