Optronics Clearnance Light Dimensions

P2-Rated or P3-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated or P3-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.

If you ever need a trailer light you will find it at, they had everyone I ever needed and at a great price with quick delivery.


Great selection of products and promptly delivered as well. Thank you!


I have bought many products gor our camper from etrailer from hitchesyo lihht bulbs. Always great service at reasonable prices, usually 30 to 50% lower than local RV dealers.

The lights are great.The only problem Ive had is there is no built-in backup warning to keep me from backing the trailer into things and breaking the lens. LOL

These lights are really good for the price! (I ordered 16)
They aren't cheap feeling or flimsy.
They feel sturdy, durable and they look quality.
The wires are the correct gauge and the light bulb is in a rubber grommet for weather sealing.
The light is sealed very well and it takes some effort to remove the lens cover.
The lens is thick and the color is true. The reflector is bright.
I was genuinely impressed with lights especially for the cost.
These will be replacing older side marker and clearance lights on my older 1985 Sunstream motor home.
My lights are faded, some broken, mostly leaking and more costly to replace than what they are worth.
These MC32RB and the Amber version lights will look great!
Slightly different style, same size and better looking and better quality than the originals.
Very happy with lights and etrailer.
Will be ordering more items.


I purchased red and amber lights to replace the faded and broken ones on my travel trailer. Camping World wasn't able to help me. Found you all while searching the internet. Great produce. Great price. Better than the originals. The screws that secure the lights to the trailer are protected from the weather (they are under the removable lens. Easy to install. Ended up replacing all eleven lights.

Work and look great. Again, installation was easy.

The service was fast and the item was just as described.


Thank you very good service.


Lights worked great as side lights. Look very good.


Great price fast delivery


Tracking let me know when to expect these. They arrived on time, and in good shape. Installed them, and they work great. Bright bulbs, simple install. Great price too! Thanks again!


Perfect snug fit.


Just exactly what I needed to replace old sun aged lights and are priced just right thank you etrailer


Bought these for replacements on my 1989 pop up. Exactly as described. Came with light bulb and wires. Very happy.


As advertised. Quick shipping


Exactly what I needed. Takes a hot minute to receive, but fixed my problem of missing/damaged marker lights.


Great products


I have a trailer that did not meet DOT Regs. I needed to install amber side lights. Your amber light mc32ab was just perfect for what I wanted. Very low price and the light fit on the side of the trailer with no problem. Very good light for the money.

I have had no problem at all. The light holds up well and still looks new.
Rich S - 09/12/2018


I was expecting a one-wire light, instead it had two so I had to improise grouning the second wire. Otherwise good replacement for old light.


Excellent lights


My marker lights were terrible to say the least dim not working correctly, I decided to go to LED that didn't work because of how my coach is wired with a floating ground, so I picked up these lights instead . They assembled in the same exact place and wired exactly the same now with all the lights grounded correctly they work perfect as a clearance/turn signal lamp bright and the new lights gave it a cleaner appearance i didnt want to fight to run a new ground for the LED ... so with very little work about 5 minutes per light . I'm looking good feeling good


Great price. Fast delivery


This is just what my old trailer needed. I ordered 7 Amber and 7 Red clearance lights and with in 90 minutes had them all installed and when I plugged in the trailer they all came one. I was one happy camper.
For years I fought with old weathered lights with lots of corrosion and now I'm plug and play with no worries of "Are my lights going to work this time".
The price can't be beat and due to time constraints I had to two day ship these and they showed up right when promised.
I couldn't be happy with either the product or the service and shipping. Thanks ETrailer!!


These side markers are great. The reflector lenses must be removed to gain access to the mounting holes. I purchased four of these to install on a hitch-cargo-carrier: after bolting them in, I went to installing the reflector lenses back onto the lights. Three snapped on perfectly; however, on the fourth one, it did not seem to "snap" in place as the others did. I literally drove 2,500 miles with the cargo-carrier-lights assembly on me vehicle (at times in heavy rain or heavy snow). All lenses staying in place, all lights working fine; I have to say this is a great purchase. I still enjoy showing off my lights even after the long trip :)


It's just a light cover so can't say much about it but what I will say is the customer service at this company is Fantastic. My order was very small but they treated me as if I was spending a ton of $. Not only that the shipping was super fast, and the packaging was done in a way that my products were extremely well protected from the shipping gorillas. They have won my business and I am telling all my friends. Thank you for a job well done!


I thought I had ordered LED marker lights, but I must have been mistaken, which is likely my fault. If you have such a thing in an LED configuration, let me know.

The LED counterpart to this light is part # MCL32AB
