12 volt ideas for exterior of camper???

Now that I've removed my electric stabilizer jacks from my camper, I need to cover the hole where the switch for the jacks were located. I thought about just covering it with some sort of trim plate, but then thought it would be a shame not to utilize the existing 12 volt power that's already run to this location. I thought about a 12 volt led light or possibly a cigarette power plug. Does anyone have other ideas? I want it to be functional and also completely cover the hole from where I removed the jack switch. If you have a link to go along with the idea, that would be great. Thanks.
