Old incandescent bulbs can’t match the output or reliability of LEDs like these. This 6-1/2" x 2-1/16" oval light uses four amber LEDs under a clear lens for bright, uniform illumination while drawing only 0.12 amps at 12.8V. It gives you more visibility with less power demand, meaning fewer issues with dimming or overload on your trailer wiring. And because there are no fragile filaments, there’s nothing to burn out or shake loose over time.
When lights go under water or face heavy road spray, leaks quickly ruin the circuit board. This M1 Millennium Series light is sealed from end to end—both the housing and the lens are waterproof and fully submersible. The sealed circuit board protects the diodes from corrosion or shorting, making it ideal for trailers that see rain, washdowns, or the boat ramp.
Mounting this light is straightforward and tidy. It’s designed for surface mounting with 4-5/8" center-to-center bolt spacing and a slim 3/4" thickness that sits close to the trailer body. The two-wire design with 0.180 male bullets keeps wiring simple—power and ground only—without extra adapters or connectors. A matching chrome bezel (00212317B, sold separately) can be added for a finished look if you want an extra touch of style.
Visibility is key for safety, and this light’s P2 rating ensures a clear beam pattern where it’s needed most. It projects light 45 degrees to either side of center for 90 degrees of total coverage, making it suitable as either a clearance or side marker light when properly mounted. That focused spread marks your trailer’s edges so other drivers can see it clearly in low-light conditions.

Speaker 1: Today we're taking a look at the Optronics Millenium Series LED Amber Clearance or Side Marker Light.This light adds or replaces a clearance or side marker light on your trailer. It features a completely sealed waterproof design, and it's a two wire design, so you have one wire for power and one wire for ground. These do have the .180 male bullet connectors on them, so you can actually, if you don't want to use these, you can cut these off, strip back the wiring for hard-wired applications.This is a LED system. LEDs make great replacements for incandescent lights. They last longer and burn brighter and they're much more efficient. You don't have to worry about replacing bulbs or worry about brittle filaments with an LED system.It has a nice clear lens with a white mounting base, and then the LEDs are amber in color.
It's a surface mount installation, hardware not included, but you can see your two pre-drilled mount holes, and then it does require a 3/4" diameter hole for this are right here for flush mounting. If you want to add a finished look to the light, you can add a bezel. We offer a chrome mounting bezel, available and sold separately with part number 00212317B. This is a P2 rated light. It's Department of Transportation compliant.A few measurements to go over with you real quick, and then we'll hook it up to power so you can see what it looks like with power running to it.
Overall length measurement is about 6-1/2". Top to bottom is about 2-1/16, and then the mount holes on the unit are separated on center by about 4-5/8", and the overall depth from the back of the housing, the flat piece right here, to the front of the lens is about 3/4" deep.We're going to go and hook it up to power. That way you can see what it looks like with some power running to it. You can see here it sends out a nice, consistent signal. We're looking at four LEDs on this unit, so the multi diode design really helps optimize the light output.
Power draw at 12.8 volts is 0.12 amps, and Optronics puts a lifetime warranty on the LEDs.That's going to do it for today's look at the Optronics Millenium Series LED Amber Clearance or Side Marker Light.
