Optronics MCL32 Series LED Side Marker and Clearance Light with Reflex Diagram

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.

Great product, good price and fast shipping. Perfect replacement for the clearance lights on our 2020 Grand Design 311 BHS.


Works great. holds my wires and keeps them covered.


LEDS are SO much better. The light is crisp and strong. Incandescent bulbs can't compete. The install was easy and an exact match to the incandescent I replaced

Ive only used one and the rest were for the future. . The reason being that I got the trade-in fever and these lights do not fit my new TT, so they made their way to the trash.

Poor packaging, wrong tail lamp. You gave me an led and an incandescent tail lamp. Not what I ordered. I’ve had problems in the past but decided to give you another chance.

I am sorry that we sent the incorrect light out to you. I will have our customer service team reach out so that we can have this taken care of right away.

I sent an email asking to have my prior purchase looked up as I needed a replacement side marker light, a day and 1/2, I got a reply with the answer I was looking for.


Fast service


I wasn't really sure what I needed but Marissa B. Found what I needed. Marissa was very helpful. She took my order and before i knew it, it was here. Thanks, Marissa B,


Much brighter than the original.Simple swap out and go.


Etrailer is the best!


I replaced all the clearance lights and taillights on our fifth wheel camper with these OE style LED versions. They are much brighter and therefore much safer, especially in the case of the tail/brake/turn lights seen elsewhere at etrailer. They should last a lot longer than the original bulb units. I also like the way they look as compared to the old bulb style. Our camper was only a year old, and I don't understand why they all wouldn't come from the factory with LEDs. I installed them all myself without issue.

Thank you for your follow up. I am still happy with my purchase,although they are installed on a fifth wheel camper trailer that doesnt getused a lot and usually in the daylight hours, so the lights havent got alot of hours on them. So far, so good. Thanks again.

Replaced taillight with LED so decided to change running lights as well!


these led lights look awesome on my bass boat perfect fit


Bright little S.O.B. And should do the trick for my grounding problem. I needed room behind the light to screw the ground wire to the skin of the R.V. Since all I have is one hot wire coming out for placement of the lights.
Was told the gap behind the light was 3/8 of an inch but its more like 1/4 inch but should be enough room for a flat head screw with a wire under it.
Will use silicon to seal the screw and wire to keep it from rusting, the problem I had with the old lights using the mounting screw to ground the lights to the skin of the R.V.
Time will tell if all works out?? As planned.

Good, no problems

Perfect service


WOW!!! Am I glad I ordered these to replace the original OEM ones on my fifth wheel camper! I truly am so impressed with these guys, way way brighter than the incandescent ones!!! They were super easy to change out and wire up probably took around five minutes a light. The folks at are AWESOME to work with, very efficient about following up on order received when it ships and when it is delivered! Keep up the great work! Thank you!!!!

Thank you once again, still money well spent!! Look very nice and much better than OEM! Thanks!

I’m very happy with these LED tail lights. Bought them to replace the ones that came on the trailer. They are bright and seem to be of high quality. They were easy to install. The only slight drawback is that it’s a bit tricky to get the wires to lay flat enough against the light to get it to sit flush with the back of the trailer. But in the end it worked fine. I would recommend these as a good replacement for older, smaller, incandescent tail lights.


We purchased these LED lights for our horse trailer remodel. Love them and the LED lighting really modernizes the look of the trailer. We have purchased these lights for the sides and the same light in red for the rear of the trailer. We are delighted with the service provided by We have purchased from them several times and will continue to use them for our trailer parts.


I have ordered several times from etrailer and both times have been very satisfied with their service and the products. I have several different trailers, stock trailer, flatbed utility trailer, small bumper pull camper and a 5th wheel camper and for every one of these trailers, if I need parts I first look to etrailer.


I have bought several items over the past few years from etrailer and get great customer service and good products always. The prices are good and the time it takes to get the product is pretty fast.

All your products are great and work very good

As described. Nice replacement for my old running lights.

Richard E - 06/13/2020


Very quick on the shipment and very easy to install. They are really nice and bright which is what I was trying to achieve on my 5th wheel . I installed all clearance and running lights, couldn't beat the price and quality.
I don't have any pictures but when I plugged it in (full sun) and backed away from rear the lights were bright! I am thoroughly pleased.


The lights are great! Perfect fit, exact mounting hole alignment and much brighter than before. Susan was fantastic and extremely helpful. A person could not ask for a better service representative. I give etrailer and Susan 5 stars plus. I'm truly an etrailer fan and they are good managing exchanges if an item doesn't fit, etc. You won't do better than etrailer.


Excellent product, easy to install and a perfect fit. I plan on replacing the remainder of the lights with these LED's as the bulbs burn out on the originals.

Excellent. Still functioning well
Robert - 01/11/2019


Easy to install once I figured out which wire on my camper was hot and which was ground. Not the light's fault, the builder used black wire for everything. A great product at a reasonable price


Great quality products that arrived really fast. The videos attached made hooking up the lights a breeze. I saved approx 50% compared to our local trailer shop

Everything is working perfectly. I have used this trailer every weekend this year. Lots of mud and water. No issues at all. Im proud when I see my trailers lights so much brighter than other guys trailers. Happy Canadian here!!
