I didn't like the hole in the tailgate for the emergency triangle we don't get included with the car here in Canada so I built an LED light to fit in there.

Used an LED strip on each side

and a sanded piece of PETG for the diffuser

took apart an old battery holder for the metal parts. the switch hole isn't ideal as you need to lower the bracket to turn it on. I may revisit in the future.
