Optronics MCL50 Series Miro-Flex Amber LED Marker 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 diodes or circuit board.

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 Trailer Lights - Clearance Lights - MCL50AB Review

Today we're going to be taking a look at part number MCL50AB. This is the sealed MirroFlex 2 inch round LED trailer side marker, clearance, or identification light. LED systems are going to make great replacements for incandescent lights, they're going to burn brighter, they're going to last longer and they're much more efficient. Also with LED systems you don't have to worry about replacing bulbs, you don't have to worry about brittle filaments. This one is going to be sealed and waterproof when it comes to the lens and the housing unit. This is a grommet mount installation, you're grommet is going to be sold separately.

You can find that here on our website with part number A54GB. Here on the back side it's got a 2 prong connection so it's going to accept the industry standard 2 prong plug that's also required and sold separately, you can find those here on our website as well. This light is going to contain 9 amber LED's. Its going to give us a diameter, measuring the back side here, of 2 inches. Its going give us a depth of 1 3/16 of an inch. The MirroFlex technology is going to increase light output while using 90 percent less energy than incandescence lights.

It's going to have a really nice contemporary appearance but it's going to maintain that traditional footprint of a round 2 inch side marker, clearance, or identification light. The LED light is going to draw 0.187 amps at 12.8 volts. It is department of transportation approved and Optronics is going to put a lifetime warranty on the LED's. We're going to hook it up to our actual power source, that way you can see what it looks like with power running to it. I have an industry standard 2 prong plug here today so it simply just connects into the prongs on the back side, snaps in for a nice tight seal. So you can see here again it's going to have 9 LED's, sends out a really nice consistent signal, strong light output.

LED's are going to have a very quick response time. Again, they're going to burn brighter, they're going to be much more efficient, and once again, this light is going to work as your trailer side marker, clearance, or identification light. That's going to do it for today's review of part number MCL50AB this is the sealed MirroFlex 2 inch round LED trailer light. .

Perfect fit. 472672


Greetings, I really enjoy having the trailer. We took a six day trip back in may of this year. It was great having all that room. We've also taken it on two or three day rides just in case we saw something at a craft shop or even a yard sale. Lol Each trip included a picnic lunch. I did modify the lighting on the trailer. I ride a 2014 Goldwing, and after the two, 5 to 4 wiring adapters failed I added two 3" LED turn signals near the top of the box. See photo. I may even add a third member brake/tail light to the lid rack bracket. Thanks, 453791


Those are the taillights I'm using on my teardrop Trailers,looks really good .Egon 448817

  • Recommended Red Clearance Light to Match Amber Clearance Light
    I believe you are looking for the Sealed, Miro-Flex, 2" Round, LED Trailer Side Marker, Clearance or ID Light, 9 Diode - Red # MCL50RB to go along with the Sealed, Miro-Flex, 2" Round, LED Trailer Side Marker, Clearance or ID Light, 9 Diode - Amber # MCL50AB for your trailer. You will also want the Right Angle 2-Wire Pigtail for Optronics Trailer Lights - 2-Prong PL-10 Plug - 6" Lead # A46PB and the 2" Round Grommet - Flush Mount - Open Back # A54GB for this installation.

  • Does Light # MCL50AB Use the Same Grommet as Light # MC53AB
    Yes, the Sealed Miro-Flex 2" Round LED Trailer Side Marker part # MCL50AB will fit in the same grommet as the Sealed 2" Round Trailer Clearance and Side Marker Light part # MC53AB as they are both exactly 2" diameter. The LED option however is 1-3/16" tall whereas the incandescent option is 11/16" tall but as you mentioned this should not be a problem. If you need a new grommet then you can use the 2" Round Grommet part # A54GB.

  • What is the Minimum Depth Required to Mount Optronics Clearance Light # MCL50AB
    With the Optronics light, # MCL50AB inserted in the grommet, # A54GB, and the wiring harness plugged in, # A46PB, from the back of the grommet where it will be touching the trailer, to the back of the plug it measures 11/16 inches. A depth of 1 inch would probably work well.

  • What Size Diameter Hole Is Needed to Install Optronics Trailer Light # MCL50AB
    To install the Optronics Trailer Light, part # MCL50AB, you will need to use 2 Inch Round Grommet, part # A54GB. The mounting hole to properly install the light # MCL50AB with the grommet should be 2-5/16 inches in diameter. This light uses a 2-wire plug, like the Two Wire Pigtail, part # A46PB. The Optronics Trailer Light # MCL50AB is a sealed, waterproof LED light. The advantage of an LED light is that it burns brighter than an incandescent light but draw less power. It is also...

  • Can LED Clearance Light Part # MCL50AB Be Used as Turn Signals
    If you wanted to use the Sealed, Miro-Flex, 2" Round, LED Trailer Side Marker # MCL50AB as a turn signal light you certainly could. For a grommet you would then want the part # A54GB and then pig tail harness part # A46PB.

  • Recommended Miro-Flex Clearance Lights With Clear Lens For Trailer
    We do offer Miro-Flex lights with clear lens for your trailer, but none of the Miro-Flex lights we carry are round with clear lens. The lights I recommend with a clear lens are part # MCL-50CRK. These lights have 3 LED diodes and come with the plug and grommet needed to install. For a round 2 inch Miro-Flex light, we offer the amber light, part # MCL50AB and the red light, part # MCL50RB. To mount these lights you would need the rubber grommet, part # a54gb, and you would need...

  • Availability of LED Amber and Red Clearance, Tail Lights, and Side Marker Trailer Lights
    The STL42RB does come in amber. It is # STL42AB. Use wiring harness # A45PB with it. For 2 inch diameter amber lights you can use # MCL50AB with # A49PB and # A54GB. For 2 inch diameter red lights you can use # MCL50RB with # A49PB and # A54GB. For amber teardrop lights, you may be able to use # CBL22AB. We also have a teardrop shape kit that you would use on the roof of a truck, # CB-15AK, but it is not LED. For red teardrop lights we also do not have an LED option but we do...

  • Do LED Turn Signals Need Load Resistors When Installed on a Jeep Wrangler
    Yes, you will need a load resistor for each LED bulb you install on a turn signal circuit. I checked your order and it looks like you bought a total of 4 LED lights, because of that I would recommend you get two sets of Putco LED Light Bulb Load-Resistors # P230004C-2. I attached installation instructions and a couple pictures for this product that shows how it installs.

  • Trailer Wiring Recommendation for a 2005 Dodge Ram
    Since you have what sounds like a factory 4-way (or wiring) installed on your 2005 Dodge Ram you would not need to worry about circuits being installed or combined and needing the correct adapter. The harness you have for your 4-way wiring is already combined and ready to go. You can use a circuit tester like part # PTW2993 to confirm that the wires you have found are correct. If you have a 4-way on your vehicle all you would need is the part # ETBC7 to install a 7-way and brake controller....
