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.

My led light failed within 1 year. etrailer is probably the only retailer that requires me to pay ship back a defective part. I have found that Optronix lights can be purchased on [online store] Shipping is faster and free. Returns? No problem.



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.



These lights are just plug and play and they look great on any trailer! I bought 4, 2 on the other side of my trailer in the same spots.


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


These lights are fantastic. I discovered that mice had damaged the front marker lights on my equipment trailer so I decided to replace them with this style light. They are much brighter than my original equipment lights and are very easy to wire and install using the 2" rubber grommets. They improve the look and visability of my trailer so much that I plan on replacing the rest of my lights with this style as well.

After a year these lights are still fantastic, just as bright as the day I installed them. No sign of aging or weathering despite this trailer being stored outside.

I ordered a couple spares due to 1 lamp losing a few leds. Lamps were still brite even without a couple leds. I'm still happy with their performance as the other 8 on this trailer have zero issues.


I bought a set last year form another distributor and were to be watertight. The ones I bought from etrailer states waterproof and they are going on a boat trailer. We will see how well they work once I launch the boat and see if any water penetrated the inside of the light.


Product is exactly as described. Fit perfectly in my snowmobile trailer as a replacement light for one that was lost during my travels. Shipping and Customer service has been awesome.


Worked as expected. Not only brighter than the original incandescent lights but the Optronics Miro-Flex product looks great even when not lit.


Replaced old side marker lights on trailer really makes a difference in looks and bright light.


Changed my equipment trailer lights over to LED. I was able to get everything I needed plus quick shipping.


I just installed 2 of these on my car trailer, replacing older incandescent lights. These are so much brighter! Great fit, easy to install. I haven’t had a chance to get them wet yet, but I’m sure they will hold up.


I wanted to replace all the lights on my trailer to LED, found what I wanted and price and quick shipping made the purchase great.


I'm very pleased with the replacement parts I ordered and received them in a timely manner I have already recommended this site too a couple of my friends.


great for front turn signals on offroad vehicles


This was a perfect replacement for my 2015 Bri-mar dump trailer. Very pleased! Very bright!


brightest clearance light i have seen.


Great price on tire and wheel combo, ordered LED lights also but haven't installed them yet. Placed my order on Sunday night, shipped out Monday morning received shipment Wednesday morning, great job.Randy


Everything fit perfect, no
problems at all!!!When I get ready to do my other
trailer light I will be calling you!!


Products works great after use for a year and I have found other parts from this vendor that work well and last a long time.


Great product and even greater service from etrailer!


Overall good light, but it's about 1/2 inch thicker than a standard side marker and therefore sticks out from the rubber housing further.


Very bright led marker lights.


Great products and quick delivery. All the lights fit even better than expected


Received all the LED lights on time - and they all worked as described. Very good purchase.

  • Recommended Amber Clearance Light To Replace Glo-Brite 9500-88
    I would be happy to help! While we do not carry the Glo-Brite 9500-88 you have in your trailer, we do have a light that will work as a replacement for you. Based on the information I could find on your light it measures 2" in diameter, and based on the picture you provided it mounts in a grommet. We have the Miro-Flex LED Clearance or Side Marker Light w/ Reflector - Submersible - 9 Diodes - Amber Lens # MCL50AB which is 2" diameter and will fit perfectly in your grommet. You will need...

  • 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.

  • 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.

  • 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 either...

  • 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.

  • 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.

  • 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 LED Light Bulb Load-Resistors # DI34ZR. I attached installation instructions and a couple pictures for this product that shows how it installs.

    To install the Optronics Trailer Light, part # MCL50AB, you will need to use 2 Inch Round Grommet, part # A54GB.

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 great...

  • 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 have the...

  • 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....
