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.

LED Clearance or Side Marker Trailer Light w/ Reflector - 1 Diode - Oval - Red Lens - MCL0030RBB

Average Customer Rating:  4.9 out of 5 stars   (78 Customer Reviews)

3-3/4" x 1-13/16" Oval. Low-profile trailer light serves as either a side marker or clearance light. Built-in reflex reflector. Snap-on polycarbonate lens. Surface mount - hardware not included. 2-Wire design. P2 rated.


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.


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.



A year later and they are working like new. No problems what so ever.


Part was correct and I received it quickly. Have used e-trailer many times and always a +.


Somewhat tricky to replace the "Brite" oval lights on my Itasca Navion. I recommend that you cut the wires to the existing light as close to the bulb as possible to give the most to work with. I used blue crimp connectors and existing holes by angling the mounting screws. Looks very similar to the OEM lights in the daytime. I haven't compared the lights at night.


Like the brightness and look. Only complaint would be the foam gasket instead of rubber. When I drilled out the mounting holes, the foam wrapped around the bit tearing the foam. Another idea would be to have holes in the gasket lining up with the mounting holes.


Identical replacement!



1 year, still works perfectly


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 bought these optronics marker lights for my Winnebago View a year ago, but needed to replace one. They were still available, so I got a couple, to have a spare one, in case I may need it later. They are an almost perfect replacement for the original marker lights on the back end of the RV. Kathy was very helpful in filling my order.


prefect match for my trailer


Exact light replacement. Excellent quality and fast delivery. Dry pleased with this purchase and I will continue to use and recommend etrailer for trailer supplies!!!


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.


Great service. Excellent inventory for difficult to find items. Shipping cost is reasonable. Thank you!


Recieved order promptly. Had been waiting since April for order from local RV dealer. Still waiting!!


Great service


Helpful customer service. Spent time on phone to explain things. Very helpful Fast delivery. Thank You.


Great service, great product


Great replacement for Winnebago View


Lights worked well. There were no issu es.


Quick response, quick delivery!


Perfect fit!!!


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.


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.


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.


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


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!

  • How To Find Replacement Rear Clearance Lights for a 2008 Fleetwood Southwind
    In order to find the correct replacement rear clearance lights for a 2008 Fleetwood Southwind you'll need to take some measurements, note the shape and color then choose from our selection which I have attached for you below. I don't have a way to look this up for you. The lights appear to be oval so something like the LED Clearance or Side Marker Trailer Light part # MCL0030RBB may work.

  • Correct Replacement Lens for LED Clearance or Side Marker Trailer Light MCL0030RBB
    We do offer a replacement lens for the LED Clearance or Side Marker Trailer Light part # MCL0030RBB, it's the Replacement Lens for Optronics part # A0028RB. That said, for only a few more bucks you can get a new assembly with bulb so I would just get a new light if I were you.

  • Replacement Red and Amber Clearance Lights For a 2008 Winnebago Adventurer 35L
    It looks like you will need to replace the entire light assemblies on your 2008 Winnebago Adventurer 35L as the lens mounts for the Optronics MCL0028 # A0028AB uses a different mounting style than the lights on your Adventurer. You current lights are discontinued and no longer available. I recommend replacing your current assemblies with the Amber LED Clearance Light # MCL0030ABB and Red LED Clearance Light # MCL0030RBB. These LED assemblies won't require you to replace bulbs like your...

  • Replacement Clearance Lights For Glo Brite 122r/122y
    The Optronics LED Clearance or Side Marker Trailer Light is available in Red # MCL0030RBB and Amber # MCL0030ABB. These are the closest replacements to the Glo Brite 122r/122y lights you have. The lights only have one LED diode versus the 3 in your light. You are able to get a replacement lens in either Red # OPT67WR or Amber # A0028AB if your lens becomes damaged with the new lights.

  • Replacement Clearance Lights For 2007 Winnebago Sightseer RV Motorhome With Glo-Brite 122R/122Y
    I do have a recommendation for you as we do not have a direct replacement cover for the Glo-Brite 122R/122Y cover. Instead we do have the LED Clearance or Side Marker Trailer Light in Red # MCL0030RBB or Amber # MCL0030ABB. This will allow you to replace your lights and then you will be able to use the Replacement Covers in Amber # A0028AB or Red # A0028RB if one of the lenses should become damaged on the new lights.

  • Parts Needed To Add Running Lights To a Hitch Mounted Folding Cargo Carrier
    I have a couple options you might consider. First is the easiest and would involve the Auxiliary Lights # C53201. The lights themselves adhere with double sided tape to your cargo carrier and the wiring can easily be run through your center post to keep everything tidy. These lights are going to function as running lights, turn signals and brake lights. If you prefer to only use marker lights you could cut off the 2 male terminals on the connector which activate the turn/brake lights. If...
