Optronics Trailer Lights - MC53AB

Highlights

Reliable In Any Weather: Sonically sealed, waterproof housing keeps moisture out when submerged.
One Light, Two Functions: Works as both a clearance and side marker light when properly mounted.
Tough Build: Durable polycarbonate housing and lens resist impact and wear.
Simple Power Connection: Uses a standard 2-prong plug for quick wiring to 12V DC systems.
Compact Fit: 2" round recessed mount installs cleanly with grommet (sold separately).
Road Legal: DOT compliant and PC rated for full 180° visibility coverage.

Features to know about

Reliable Visibility in Any Weather: Submersible, Sonically Sealed Construction

Moisture and road spray can ruin trailer lights fast, but this one is built to handle it. The housing and amber lens are sonically sealed into a single waterproof unit, making it fully submersible. That seal keeps out water and debris, protecting the incandescent bulb and wiring inside so it stays bright and dependable whether you’re driving through rain or backing into the water.

Compact Powerhouse for Marking and Clearance: 2" Round, PC Rated Light

You don’t need a big light to make a big difference in safety. At just 2" in diameter and 11/16" thick, this round amber light gives off a wide 180-degree beam pattern thanks to its PC rating. When mounted properly, it works as both a clearance and side marker light so others can see you from straight on or from the side even in low light.

Straightforward Setup: Recessed Mount with Standard Plug Compatibility

Installing this light is simple. It uses a recessed mount with grommet (A54GB sold separately) and accepts an industry-standard 2-prong plug like the A46PB or A86PB. The design makes wiring clean and quick without special adapters, so you can get back on the road with minimal effort.

Durable Build That Lasts: Polycarbonate Housing and Replaceable Bulb

Built for rough use, the polycarbonate housing and snap-on amber lens take on vibration and impact without cracking. The incandescent bulb is easy to replace if needed, keeping maintenance simple over time. It runs on 12V DC systems with a low 0.2-amp draw at 12.8V, giving you reliable light without overloading your circuit.

DOT Compliant and Backed by a 3-Year Warranty

This light meets DOT requirements for visibility and function, so you can count on it for safe, compliant lighting wherever you go. It’s also backed by a 3-year warranty for extra peace of mind.

High quality, inexpensive marker light. Easy to install, it happened to be in my mailbox as I was departing with the trailer so I just popped it in. Matches the OEM lights on the trailer.

The Clearance lights we got from you a year ago are working just fine. My husband had to do some new rewiring to get them to work because the wiring that was there was terribly old. But he got the new ones to work. We have a 1973 Nomad trailer I inherited from my parents and I need new tail light covers because they are badly faded but I'm having a hard time finding them because they are rectangular, approximately 8 3/4 x 4 1/4. If you could help me find two of them I would greatly appreciate it. Thank you

The clearance lights we got to replace the old ones on the camp trailer are working great. Thanks

I was online looking for a source for 2 in round push in lights for flatbed on my truck. I came across etrailer and I found what I needed and pricing was super low and got a quality light as well. They shipped them promptly and received them within 1 day because of choice of 1 day shipping . I will be back for more stuff for my 3 trailers I own . Good job guys and gals. Thanks.

I ordered these running lights to replace the originals on the 1997 boat trailer that I purchased used. One of the original lights (?), although "sealed" / "submersible", actually failed when submersed. I don't know how long the original lasted, but I know that the previous owner stored the boat outside and the freeze/thaw cycle could have caused the failure.

Before I installed the new one, I added a small bead of silicon sealant as a "backup" to the factory sonic sealing. Hopefully I'll be able to upgrade this rating in a few years.

by: Todd S 08/27/2020 One Year Later

Exactly what i needed! So glad I found etrailer. Not that I mind using dealers and repair shops on occasion, but I also prefer to save money on those projects that i can take on myself. The clearance lights were a perfect replacement and a quality product. Fast shipping was appreciated!

by: Bought these lights 1 year ago and they are workin 08/08/2017 One Year Later

Bought these lights for my trailer 1 year ago and they are working like a champ. These sealed lights are not expensive and no hassle. Unplug and plug in. Very simple.

by: Donald P. 09/13/2019

In total, I purchased electric tongue jack, double roller for rear ramp door, vent cover, new backing plates (four) complete with electric brakes, new hubs and bearings.
This time wheel covers for two trailers and some lights for quad trailer.
I am very pleased with everyone involved with purchases and products.
I would recommend etrailer to anyone and have already done so to some friends!!
Thanks!!!

by: Doug 02/20/2017

I had to order this Round Trailer Clearance and Side Marker Light because the replacement provided by the trailer manufacturer did not work.
This light was a perfect replacement for the original.
And I received it from ETrailer earlier than I expected.
I will continue to shop with ETrailer for all my trailer needs.

by: Charles F 04/28/2014

I have a new POLARIS aluminum trailer. I broke a side light lens cover. The dealer could not supply me a replacement. I found the exact lens at etrailer.com. The lens is an exact match and the service was very fast. The etrailer rep I talked to was very helpful and courteous.

by: Tim O 01/08/2016

I have purchased from etrailer several times and I find the selection of parts very good

I think their attempt to help customers with video and a good tech department is very unique and beneficial

The quality of the lights I received is good but I do feel it was not the same quality as the original "Grote" brand lights my trailer came equipt with...
Also the quality of the rubber grommits was definitely thinner and not as robust as all the original grommits used on the trailer originally... these parts were made over seas and the oems were all American made...

This is not meant to be a "DONT BUY" I'm just stating the facts
the parts are not the same quality but the price was great and the parts did work just fine but just bear in mind there is a difference but for my used trailer rebuild they were just fine

the jacketed wire was top notch BTW

I would buy from etrailer and these same parts again

by: BW 07/29/2023

Used these to replace the LED lights that came on my trailer. They provide a much softer light than the LEDs, which were blinding me with the constant reflection in my side mirror. Only negative is that they are sealed and you can't replace the bulb, but they are cheap enough that you can carry a couple in the glove box in case one goes out.

by: Tim F 08/08/2013

These lights were an exact replacement for my trailer marker lights. The description was good enough to help me mark the choice and I am happy that I did. Works well as everything that I have bought from etrailers has for the past 4 years! My go to place for trailer parts and accessories!

by: Warren L 03/05/2017

I priced the same items around here and I could buy three light with shipping from Etrailer.com for less than the cost of one light in the stores here.
I also like the pictures of the items which helps you order the right product and the ease of scrolling through the website to find the correct light.
Your lamps were OEM lighting that came with my trailer.

by: Rod K 09/26/2014

Perfect fit for my boat trailer. I looked all over for these lights. And your price was great as well. Thanks I will shop with etrailer for now on.

I just bought a 2006 goose neck trailer that needed some minor repair. Wanted to match existing good parts. These lights were exact in every way.

by: Jeremy P 04/09/2016

These were just the lights I needed. A great price and delivery was fast. The sealed lights are so nice and last so long compared to regular lights. Installation is easy just pop out the old one and friction fit the new one and the quick connections make the rest a breeze.

by: Sam H. 08/16/2017

Love these lights. Great price and easy to install yourself. Quick and easy order system. I love the entire process. I'm kept informed of my order, shipping, tracking and delivery. GREAT JOB!!!!

by: Bob Reid 05/09/2013

Great product and price. Fast shipping. I'll always check with your company for anything I need for my trailers. I was frustrated looking for the lights, until I came across your web page.

by: Greg 11/20/2016

I will definitely order from etrailer again. Great prices, fast and inexpensive shipping.

Replaced all my trailers lighting that needed some attention. Decided to get these and very happy I did. You should too!!

Do you have a question about this Trailer Light?

What Is Hole Size For Mounting 2 Inch Round Trailer Lights With Rubber Grommet
The item you selected, Sealed 2-1/2 Trailer Light, part # MC57AB, is a 2-1/2 inch light that will mount into a 3 inch hole using 2-1/2 inch grommet, part # A55GB. The hole size to mount a 2 inch round light flush mounted would be 2-5/16 inches. The grommet you would need for a 2 inch light would be 2 Inch Round Grommet, part # A54GB. If you are flush mounting your lights, the 2 inch light will sit inside the grommet. A 2 inch light similar to the one you selected is part # MC53AB. We...

Replacement Side Marker Light and Grommet for a Trucklite Brand Grommet and Marker Light
I went out to the warehouse and pulled grommet # A54GB and light # MC53AB. I then assemble them and the result looks exactly like your picture. I then measured the amount the lens sticks up above the grommet and came up with just under half an inch. The lens could be pressed further in. I used digital calipers to take the measurement. I also made a video showing the assembled result for you. The light takes wiring harness # A46PB if you do not already have them on your trailer.

Flush Mount Grommet and Wiring Pigtail for 2 Inch Clearance and Side Marker Lights
The Sealed, 2" Round Trailer Clearance and Side Marker Light, Flush Mount - Amber # MC53AB or the LED # MCL55AB will use the 2" Round Grommet - Flush Mount - Open Back # A54GB for installation. You will also require the wiring pigtail # A46PB which will give you 6 inches lead.

Looking for Trailer Clearance/Marker Light to Replace Trucklite Model 10
According to my research, I have found that the Trucklite model 10 clearance/side marker light measures 2-1/2 inches in diameter. Because the Optronics # MC53AB measures 2 inches in diameter, it would not be a good replacement. The Optronics # MC57AB, with its 2-1/2 inch diameter, would be the correct replacement. If you need a mounting grommet, it is available as part # A55GB. The two pin wiring pigtail is also available as part # A46PB.

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.
