Optronics MCL0030RBB Red LED Clearance Marker Light 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.

Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

I bought 3 of these marker lights to replace the original clearance lights on my RV since they were more or less the same size. With only one diode (many of my other marker lights have between 4 - 15) I was initially concerned about their brightness, but once installed I was happy with the amount of light they emit.


Identical replacement!

1 year, still works perfectly
Danronics - 05/06/2022


These led marker lights were the perfect replacement for my 17 year lights on my motor home. E trailer on hand is the slowest in processing the order and getting it out to the customer.


I bought these a year ago to replace the side rear markers on my Navion. The ones I had, used flashlight type bulbs that were on sometimes, sometimes not. I had to rap them with my knuckle and they be on for awhile again. These lights are led and are almost the same size as the ones I replaced. I had to drill a second hole though because the holes did not line up. My old lights could be seen and whether they were lit from my rear view mirrors, and I looked all the time since they were faulty. The new ones can be seen, but you can’t tell if they are lit in the daytime, but I figure they are since they are new and led.


I ordered 5 lights, and I got 5 lights. I can't have them installed until next week, so can't say if they'll really fit, or work or any of that important stuff. I paid extra to have them here by Saturday. But they arrived Thursday. That was nice, since I'm starting a road trip on Wednesday.


Works great on my 2009 Itasca Navion 24J RV!

After a year, these lights are still working great!

Wasn't sure if I ordered the correct light but it was. Great service and I received my purchase fast. Will use your company again and recommend it to all my friends.


I wired it in the center, rear, clearance light on my Navion and it was so close to OEM light that unless you studied it carefully you would never notice there was a difference. Worked great.


Excellent everyone was very helpful and kept me updated on how everything was going


I was very happy to find this reflector because the ones made by glo brite, which are used on the Winnebago Navion and Views,are no longer made. This one looks like it will be a very good match!

Excellent ease of ordering and excellent customer service from etrailer.


would be nice to have an insert for oversize screw hole


Still using this lamp as a marker light in my 2007 Navion motorhome. It works just fine. The light output seems slightly less bright and uniform compared to my OEM incandescent markers that it replaced, but still very satisfied. I would buy this again. PRO TIP: The mount holes in the lamp did not match the originals in my RV. Rather than drill new holes into the RV, I simply drilled a new hole into the lamp (and its foam seal) to match those in my RV. Worked fine.


Just what I needed,great service,fast delivery, can't go wrong with etrailer!


E-trailer is always on top of things! Korren was such a kind and enthusiastic person to work with when I needed to sort out an order I placed. 10/10 would recommend to anyone needing parts!

Thanks from the team at Imperial Truck and RV :)


Did not realize this was not submersible my mistake for not reading the description completely


I used these lights to replace the old Globrite incandescent marker lights on my 2014 Winnebago View. They were easy to install and work as they should one year later. Great price too!


Found three side marker lamps
easily available).
The delivery was quoted two to five weeks out. The were delivered in a week. Under promise and over deliver is rare customer service nowadays.


satisfactory transaction, received earlier than expected and worked perfectly


Customer service was excellent, Allison did a fantastic job finding the product I needed and it even arrived a day early! I had the running lights installed on my RV this morning and the technician did not come across any problems… I highly recommend do etrailer and give them a five star rating… God bless you all, stay safe and healthy… Thank you, A satisfied customer, Gloria


The light fits and works as it should.


I belong to a Facebook View/Navion group & your light replacements are often recommended. They are easy to install & are a perfect size.


It was an exact fit and worked finest


Haven’t had time to install these lights but they are perfect for my application


Product arrived sooner than expected ,mounting holes lined up perfectly.Installed on a winnebago vista,lights work great.Thank you for a quick delivery.


These units are great, much brighter than the old lights!
