Optronics Clearance Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the internal components.


P2-Rated or P3-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated or P3-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MC56RB Review

Today we're going to be taking a look at part number MC56RV. This is the Optronics trailer clearance or side marker light. This is a sonically sealed waterproof design when it comes to the housing and the lens. The unit is submersible. It's going to feature the red lens. We're going to have the really durable polycarbonate lens and housing, very strong and durable.

The unit's going to contain one incandescent bulb. This is designed to be a recess mount installation with built-in black flange here kind of the base of the light. Your hardware's not included but you can see that it's going to contain 3 mounting holes. We can take a measurement of the recessed portion. That's going to tell us what size hole this unit would mount into. That looks to be 2-3/4 of an inch so the light will fit into a 2-3/4 inch diameter hole.

Here on the back side you're going to see the connection point to provide power and ground to the light. This will accept your industry standard 2-prong plug. That is available here at etrailer.com. It is sold separately. The light itself is Department of Transportation compliant. It's a P2 rated light.

If we take a measurement of just the diameter of the lens portion, we're looking at about 2-1/2 inches. Overall diameter, measuring from edge to edge, we're looking at about 3-7/16 of an inch. It's going to give us a measurement from front to back of about 15/16 of an inch in depth. The distance that we'll have between the mounting holes measuring center on center, that's going to be separated by 2-11/16 of an inch. The power draw on the unit at 12.8 volts is 0.2 amps. I'm going to take a measurement from the bottom of the flange to the bottom of the recessed portion.

That's going to give us a measurement that looks to be 9/16 of an inch, so just over 1/2 inch. We're going to go and hook it up to our actual power source. That way you can see what it looks like with power running to it. I have a 2-prong plug already connected so you can see how it connects. It goes right into the connection points here on the back, pushes in for a nice tight seal and a good fit. You can see the light sends out a really nice consistent signal. Again, this is going to work as your trailer clearance or side marker light. The red circular lens allows a lot of light to come through, distributes it pretty evenly and again, the lens in the housing is going to be made from that strong polycarbonate material so it's going to stand up well to the elements and over time. That's going to do it for today's look at part number MC56RV.

They work well in place of lights with rubber grommets that won’t stay installed because the holes are worn or too big. I’ve had these on a trailer for a year and they have operated great with no problems.

I could only find my trailer light at etrailer. They don't make my type of trailer anymore so parts are hard to find. Etrailer.com had the exact replacement piece and fit like a glove. Outstanding customer service and updates on orders. Thanks
