If your trailer is using the 921 Incandescent push in light bulbs here is a replacement that I have been running since 3/20/15 or 41 nights camping. These LED run very cool and our converter did not come during any of the trips. With the incandescent lights you could hardly put your hands on the plastic covers on the lamps as they got so hot and the plug in for the base of the light turned brown on many of the light fixtures due to heat. I replaced all 20 inside lights, these bulbs come in packages of 10 each for $20.20, and I purchased two packs and got free shipping. What I ordered was 2 "GRV T10 921 194 24-3528 SMD LED Bulb Lamp Super Bright Warm White CD 12V Pack of 10 from Amazon. Also ran one light all night, still cool. Do a search, lots of information!
