My 5th wheel has one one each side in the rear. It lights up the neighhbor pretty good haha... I'm sure there would be some knocks on the door if this got turned on at a camp ground.
Mine has a weep hole in the bottom of the large lens and one side filled up over time and was running water inside the trailer through where the wiring went. I was scratching my head on that one until I noticed the weep hole was on the top and not the bottom like the other side scare light was.
My two lights are right under the roof drain spout...
The scare light on my OFF-ROAD POPUP gets used alot. It is mounted on from wall where the front deck is. Perfect light for hooking up the trailer.
