I have a 20 watt amber strobe light that has a cigarette loghter adapter on it. my new Silverado 2500 does not have a cigarrete lighter plug. I cant find an apter for USB-C yo cigarette lighter that supports 20 watts. the specs for USB-C state it can supprt 100 watts. I assume (you know how that goes) that the plug in my truck will suppoet that too, but i cant find those specs anywhere...
