When I lived on the coast several years ago I would solder small short wires to the actual bulbs then solder the ends of them to the wires to the lights. Not a perfect fix but it would usually get me through that season dipping the trailer in and out of salt water to launch boat. That was way before led lights. Its a neat little trick even for bulbs holders on boats where their not in the best shape and a person might have more time than money. Hope that helps,

ps I also carried 2 Army flashlights behind my truck seat in case I didn’t have running lights for any reason. An army flashlight has lenses in the bottom I kept the red lens in them and just clipped them on whichever side of trailer I needed a running light until I could re-solder a bulb.
