Switching to LEDs makes a big difference in brightness and efficiency. This Miro-Flex thinline trailer light uses 4 red LEDs that put out strong, even light while only drawing 0.051 amps at 12.8V. The faceted Miro-Flex reflector boosts output and gives it a clean, modern look. You get bright visibility with far less power use and no fragile bulbs to worry about.
Water damage can kill a light fast, but this one’s built to handle it. The housing and clear lens are sonically sealed into a single waterproof unit, keeping moisture completely out. It’s submersible, so even if your trailer gets dunked at a ramp or splashed on rough roads, the LEDs stay protected and working like new.
When space is limited, the slim Thinline design fits where bulkier lights won’t. Measuring just 4-1/16" long, 1-1/4" wide, and 1-1/8" thick, it mounts neatly to the surface using a bracket (A65B – sold separately). It accepts standard 1- or 2-prong plugs (A65P or A68P – sold separately), making wiring simple and clean without extra hardware fuss.
Visibility matters when you’re on the road, and this light’s P2 rating delivers a 45-degree beam to either side of center for dependable coverage straight on. It functions as a clearance or side marker light when properly mounted and meets DOT requirements for trailer lighting. You get consistent performance and safety you can count on every trip.
LEDs last up to 50 times longer than incandescent bulbs, so you can forget about frequent replacements. The polycarbonate housing and lens add extra toughness for long service life, even under rough conditions. Backed by a lifetime LED warranty, this Miro-Flex light is built for lasting reliability mile after mile.
