Upgrading from incandescent lights makes a big difference in brightness and reliability. This Thinline LED clearance or side marker light uses 4 diodes that shine bright while only drawing 0.06 amps at 12.8V. It’s a low-profile, energy-efficient design that runs cool and doesn’t burden your electrical system. With no filaments to break, the LEDs last up to 50 times longer than traditional bulbs—so you can forget about constant replacements and just enjoy a sharp, even red glow every time you flip the switch.
When space is limited, this light fits right in without sticking out. Measuring 3-15/16" long x 1-1/4" tall x 7/8" deep, it mounts cleanly on surfaces with holes spaced 3" apart on center. The Thinline Series design keeps things streamlined, making it easy to place along rails or narrow corners where bulkier lights just won’t do. It accepts industry-standard 1-prong or 2-prong plugs for a simple connection to your existing wiring setup.
Water intrusion can kill most lights, but not this one. The lens and housing are sonically sealed into a single waterproof unit, keeping moisture out even when fully submerged. That means you can count on the LEDs to stay protected from dirt, road spray, and full dips in the water—perfect for trailers that face rain, washdowns, or launch ramps on a regular basis.
You can install it exactly how you need with its flexible mounting system. It surface mounts using an open-back or self-grounding bracket (sold separately) like the A65PB in black or A67CB in chrome. The design grounds through the mounting surface for an easy single-wire setup—no extra ground wire needed when mounted to metal. The bracket holes are 3/16" in diameter, so standard 1/8" screws or rivets work perfectly to hold it secure without hassle.
This light’s P2 rating gives off a focused 45-degree beam to each side of center for a total of 90 degrees of coverage—bright enough to catch attention straight on but without glare from wide angles. It works great as either a clearance light or side marker light when properly mounted, providing dependable visibility that meets safety standards and keeps your trailer easy to see at night or in low light.

I installed these lights on our 40 ft motor coach and have put on over 40 thousand miles since install. I drive with the lights on all the time day and nite and they still work with no issues. Thank you

As mentioned in the product description above, the lamps are mounted using the pigtails and surface or grommet mounts which are sold separately. These items arent included because the mount and pigtail needed will depend on how youre mounting the lamp.
