Optronics MC44 Series Incandescent Marker Clearance Light with Reflex Dimensions

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-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 MC44RB1 Review

Today we're going to be taking a look at the Optronics Rectangular Trailer Light. This is a red, rectangular light that functions as a clearance or side marker light. It's going to feature the reflectorized lens that's DOT compliant, Department of Transportation. That eliminates the need for a separate reflector. It's going to feature a weather and corrosion resistant construction. It's going to feature a nice molded plastic housing and durable lens. That lens is replaceable. It just snaps on there, so you can replace that if it ever becomes damaged or broken or cracked.

It's going to contain one incandescent bulb that's replaceable as well. Bulb number is 194. It's a single-wire design that's going to be your power wire. The unit grounds through the mounting hardware. The mounting hardware is not included. The unit is SAE and Department of Transportation compliant. It's a surface mount installation.

If we take a measurement, the distance between our mount holes, we can see that's going to measure 3". Overall length is 4". Over width is 1-1/2". The overall depth is going to be 15/16" deep. When it comes to the power draw at 12.8 volts, we're looking at 0.4 amps. We're going to go ahead and hook it up to power.

That way you can see what it looks like with some power running to it. We'll also be able to turn off our overhead lights, so you can see it at a lower light setting. I'll go ahead and turn it on with the overhead lights on. You can see there a nice, consistent signal. Bulb comes on. Plenty of light output.

We'll do that same thing with the overhead lights turned off. Really nice signal. Again, it's going to contain one incandescent bulb, and the unit features that reflectorized lens. That's going to do it for today's look at the Optronics Rectangular Trailer Light.

Exact replacement part, works great!




by:

When I initially ordered these lights, I ordered a total of (10) orange, and (4) red - all incandescent. When the order arrived, they had shipped me (2) incandescent and (2) LED. As I called in to have them remedy this, the first individual that I spoke with implied that he didn’t believe me, and asked for proof - which I gladly provided. In an attempt to resolve this, I spent 30 minutes of my time explaining that I simply needed the replacement fixture - as the lenses are interchangeable between LED and incandescent, and twice now they have sent me replacement lenses, but no replacement fixture. I have since gone to my local trailer supply and purchased what I needed to finish the project.

Extremely disappointed in etrailer now. They have been great to work with in the past, but this time has been extremely frustrating and time consuming for 2 $4 lights.

You will receive an email from etrailer as soon as your shipment arrives requesting that you complete an online review. Just understand that if you try to resolve an issue via email correspondence, I have not had any success in doing so. I had far better luck attempting to resolve by calling into their customer service line - hopefully you’ll be connected with James Y at customer service, he was the only one that seemed to care about a frustrated customer, he was great.

  • 2-Wire Red Clearance Light That is 4 Inches Long
    For a light that is similar to the Optronics Trailer Clearance or Side Marker Light w/ Reflex Reflector - Incandescent - Red Lens # MC44RB1 but has a 2-wire design you will need the following: - Optronics LED Trailer Clearance or Side Marker Light w/ Reflex Reflector - 6 Diodes - Red Lens # MCL44RB This is the same light, with exactly the same dimensions and mounting hole spacing as the MC44RB1, with the only differences being that this is an LED light instead of incandescent, and that...

  • Replacement Lights For Optronics MC44, 1 Wire Lights In Red and Amber LED Lights
    Yes, we do have the Trailer Clearance or Side Marker Light # MC44AB1 available as an LED # MCL44AB1. This has the same 1 wire connection so the ground wire is achieved through the mounting hardware. We also have the Red LED # MCL44RB1 if you have any Red Lights # MC44RB1 you would also like to replace with LED's.
