Features to know about

Brighter and More Efficient Lighting: 9-Diode Miro-Flex LED Design

Old incandescent lights can dim over time and draw more power than they should. This 2" round amber LED light uses 9 diodes behind a Miro-Flex faceted reflector, pushing out a bright, even glow while using just 0.047 amps at 12.8V. The LEDs last up to 50 times longer than standard bulbs, so you won’t be dealing with broken filaments or frequent replacements. It’s a clean, modern look that stays bright while keeping power demand low.

Built for Wet Conditions: Sonically Sealed and Waterproof

Water intrusion is one of the fastest ways to ruin a trailer light, but this one is made to handle it. The housing and acrylic lens are sonically sealed into a single waterproof unit, so no moisture can sneak in and damage the circuit board or LEDs. Whether you’re driving through heavy rain or launching a trailer into the water, it’s fully submersible and stays reliable trip after trip.

Simple Fit and Clean Mounting: Recessed 2" Installation

This light is made for an easy recessed mount using grommet A54GB (sold separately). It fits a 2-5/16" diameter hole and accepts an industry-standard 2-prong plug like the A46PB pigtail. Once in place, it sits flush for a clean look that won’t snag or stick out awkwardly. With only two wires to connect—one for power and one for ground—it’s quick to wire up and ready to go.

Reliable Safety Coverage: P2-Rated for Clear Visibility

Visibility from the right angles makes a big difference on the road. This P2-rated light shines a 45-degree beam to each side of centerline, giving you 90 degrees of coverage straight ahead. That means it works perfectly as a clearance or side marker light when properly mounted, making sure your trailer stays visible without blinding other drivers.

Durable Construction That Lasts

A rugged ABS housing paired with an amber acrylic lens keeps this light protected from impacts and wear. Designed for 12V DC systems and backed by a lifetime warranty on the LEDs, it’s built to keep working season after season without you having to think about it again once it’s installed.

Product is exactly what was advertised excellent service personnel quick shipping will definitely buy from again.

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.



by:

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.



by:

Great product and even greater service from etrailer!



by:

Great Pricing, shipping and service as always !



by:

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



by:

brightest clearance light i have seen.



by:

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



by:

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.



by:

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



by:

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.



by:

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



by:

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.



by:

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.



by:

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.



by:

Look great over the factory bulbs. Much brighter.



by:

Perfect replacement and still working.



by:

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.



by:

Extra bright and exact fit.

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,



by:

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



by:

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.

  • 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....

  • 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.

  • 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 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...
