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.

Well, they are just lights – amber and red. But, I upgraded all my trailer lights to LED’s, and these continue to look and function great.


Work fine. would be nice to have wire reliefs in the back like the older incandescent lights had that I replaced. I had to go in and drill a hole through the trailer frame for the wires to go through.


Makes my vintage Alaskan camper look great. Front and back

Perfectly. Working as expected. I have referred e trailer to many people and friends. Thank you

Etrailer is really good at getting quality products to you as quickly as humanly possible. This is my go to company for my boat trailer and travel trailer parts.


This is my second order of these lights. The first order was a test to see if I like the way they look to replace my old cracked and dirty incandescent lights. Once I put the new lights on my trailer, I knew I had to replace all of my lights because they look so great! They make my old 1999 Jayco look like new!


Arrived quickly. Priced fairly. Would use this company again.

A year later. Still working! Havent needed to order anything from this company again, but I would!

Takes a lickin & keeps on tickin!

Great shipping time, and easy installat ion.


The lights arrived quickly I was able to install them exactly where the old lights were .the.measurements on the new lights. We're exact. Great clearance lights for our RV
Will order more as the old bulb style quit working.


Look good. Can't wait to install them!


Great customer service.


I recently placed two separate orders (the side marker lights and a new jack) with etrailer and both arrived quickly (despite opting for ground shipping) and the quality of the items is great. I wholeheartedly recommend etrailer to anyone needing any type of trailer parts/supplies.

Lights and jack are working great. Would buy again.

I bought the whole set of LED lights - side and front side marker, tail lights, rear marker bar. It was quite a project getting them all in as they were of course slightly different than the 13-year old originals. But it turned out well and I was very pleased with the quality of all the components.

All trailer parts are doing well. Saltwater even.

I purchased trailer lighting for my flatbed trailer. Very satisfied with the parts and the service I received. Will use you again when the need arises.


I was not satisfied with some of the lenses when the product arrived. Some of them were scratched due to bad packaging. I contacted etrailer and they were willing to send new light assemblies. Due to the fact it was just the lenses I decided that new lenses would be fine. They sent the new lenses immediately. I was very happy with their customer service and am very happy with the product and I plan on doing business with them in the future for some interior lighting upgrades. I have an older motor home and my old clearance lights were cracked and parts for them are becoming hard to find. The new LED lights really look good, are very bright, and I don't have to worry about changing bulbs anymore


Changed out the factory marker lights to these LED markers on our 2018 Grand Design Reflection 5th wheel. Made a big improvement in increased visibility for both daytime and nighttime driving. The installation went well & I found using a putty knife made for easy removal of the original silicone caulk material. I purchased enough of these new LED's in both the red & yellow to change everything out. After doing the first 1/2 of the project I did a comparison with the new LED markers & the original ones and the advantages were quite obvious! Also swapped out the tail/brake lights to LED's & a big improvement there also, along with the added driving safety.


Great replacement for incandescent type side marker light.


Nice LED marker lights for camper. Easy to install. Don't have to worry about bulbs and sockets rusting.

Very nice. Bright and trouble free
David T - 06/18/2018


Historically I've always really appreciated Etrailers interface and thoroughness. This time, my items arrived with very haphazard packaging, no bubble wrap or paper, just the lights bouncing into one another for its journey to me. Not a big deal, but annoying none the less and makes you wonder if some potentially weak solder sections could be affected with the needless joslting. Again, small issue, but annoying.


Perfect product for our application. We installed LED side marker and stop/tail lights on our race trailer. Less amperage draw on the electrical system and brighter lights for increased safety. Have ordered many LED lights from etrailer and have been extremely satified with the quality of the products and the service.


great products and fast service


It will allow to to adjust the tow height of my Coleman Columbia tent trailer. I use two different vehicles and due to the load in them I can level the trailer for easier towing. I give it 6 stars out of 5.

Bryan J - 07/29/2016


I would like to thank the staff at etrailer for their service. I have always had a good experience with any products from the company. I have just up dated a Rv trailer to all LED lights. I did it for the safety factor. The prices that etrailer had were right in line with other stores. The free shipping saves alot . They ship fast and stand behind what they sell. No questions ask. I had one tail light that was bad and did not work correctly, they set me a new one and sent me a email shipping label to the send the other back. You can,t do better than that. Thanks again. You will see my name again. Keep up the good company service.


Solid product. Was a perfect replacement for my OEM light that was broken.

Great. Shining brightly!
