My bed lights started going out when I was driving in the rained the only way to get them to come back on was to turn the key off and back on now it has gotten worse when I hit a bump the will blink or go out I have checked all the bed wiring and bulbs can't find anything I'm going to check the trailer plug to day by the way the cab lights and front lights stay on when the bed light go off

 

Thanks for the ideas but I ordered a water proof switch from Ford. My buddy's F150 has the bed lights with that switch. It's only $28. As for wiring it up the 7 way plug is in my bed right beside the lights mount. So it's a no brainer for picking power from there. I didn't want to make it too expensive as I
picked up the factory lights for $50
