Outfitting your rig is straightforward with Diamond trailer lights. Pick what you need—tail or marker—with surface-mount or recessed styles, and choose LED options to boost visibility. Match your wiring (pigtail leads or ground-through-mount) and confirm dimensions and hole spacing so the swap goes smoothly.
Plan for either a 2-wire hookup or a ground through the mounting hardware ("wireless" ground). Test with a 12V bench battery first and label each circuit. If using number 10 self-tapping screws you may need to bore mounting holes slightly; size 8 can avoid that. Solder and heat shrink to help keep connections waterproof.
They can be, but not in every case. Some found them much brighter, while one note said not as bright as OEM. If brightness is a priority, compare dimensions and lens style, and test the light with a 12V bench battery before mounting to confirm output suits your needs and that all LEDs light up.
Yes, they've been installed on motorcoaches, enclosed cargo trailers, RV bumpers, and utility boxes. Pick the functions you need, like brake, tail, turn, marker, or back up. If adding lights higher up for visibility, confirm your wiring supports those functions and that the mounting surface is suitable.
Sometimes yes, sometimes you'll need to drill new ones. There are reports of exact replacements that installed easily, and also cases where they did not fit OEM holes and new holes were needed. Measure overall size, mounting hole spacing, and depth if your lights are recessed and the lens sits flush. If the new light is a bit larger, plan your layout before drilling.
