Optronics MCL0030ABB Amber 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.

Just what I was looking for to replace broken Clearence lights on my RV.



Very well. No problems with them. Used with rewiring the trailer.


Perfect replacement for the clearance lights on the front of our Arctic Fox. Thanks E-Trailer for always having the part we need at a great price!


My 2011 Winnebago Adventurer has clearaights that are frenched into the crown and similar to these. People have complained about loosing the lenses and they’re no longer available. I bought 2 of these and used them to replace my 2 side marker lights in the case that I should ever loose a clearance lens. I’d have a couple replacements. These leds are similar in size but the mounting holes don’t line up so I had the drill new ones and caulk the old ones but others than that, very pleased.


The installation of the Roadmaster anti-swaybar (1139-176) along with the Roadmaster end links was and easy installation. The videos that are provided by etrailer were very helpful.


These are the perfect replacement for Forest River Forester and Sunseeker Class C RV clearance lights which no longer have replacement lenses for the incandescent light bulbs.



Perfect replacement and upgrade for the discontinued clearance marker lights on the Forest River RV models


They fit the recess off my 2010 class C. No more water in the old incandescent lights with the cracked lenses.
These worked out well.


As mentioned in other's comments, these were the only, almost identical replacement for the factory clearance markers for my 2015 forest river sunseeker.
They saved me a ton of time.
Great product.
Quick install.


I used these to upgrade my clearance lights on my RV. They are almost identical to the old lights which are obsolete.



All the lights I replaced are still functioning. I would buy again


The side marker lights on our 2007 Tiffin Allegro Bay motorhome went out just before we were leaving in a trip. We had one day to replace them and the ones we had would not fit in the recessed area provided for the light. This light fit in the recessed area and etrailer got them to us in less than 24 hours. They are installed and looking great for our trip tomorrow. I will order the lights for the other side when we get back before they go out.


Fast shipping great product


Had them for a year and they've been working
great. This was a Exact replacement for my Micro Lite.


So far, so good. Product simple to install, works just fine. Haven't taken road trip yet with lights on for extended period of time.



They work.


They fit the older Class C and work gre at.


Went to move our camper less than a week ago and noticed that one of the red side marker lights was not working. Found these exact replacements at etraier for our 2020 Northwood Mfg. Wolf Creek 850 pickup camper and purchased two red and one amber marker lights. Replaced the broken red light and have the extra spare red and amber lights on hand just in case.


They look great just as I was hoping that I ordered. Took 2 weeks to receive but they had to cross the border into Canada so it was expected.


I got 2023 forest River Rockwood 2906 BS.
Perfect match! Same as factory.


Replaced a marker light that I no longer could get a replacement lense for. Very close to the same size as the original and led to boot. Worked great and will likely outlast all the other clearance lights on my coach


What I needed for a replacement, on an RV that’s 2-years old. Priced very reasonable. Fun Town RV sold me the unit, but wanted $30.00 for a replacement clearance light...


Great service


Lights are an exact match for my 2021 Flagstaff FTL22FBS. Delivered on time & packaged well
Very Pleased


I didn't actually use it on a trailer. I have an Class C motorhome and the front top clearance lights were recessed. I ordered this specifically to fit with in the recess. I have been using this for over a year and I am pleased with the results. I would buy it again. Normally I don't give a review of 5 out but I am doing so because etrailer took the time to give out enough information in the description that I was able to order what I needed.


This is nearly a perfect replacement for Forester RVs that lose their front marker lights. The dimensions (height and width) are close enough to the same as the OEM (that are no longer available). Though the depth is different, so if you're particular about appearance replace them in pairs.


I ordered two lights and one was defective.The 5 stars are for the excellent customer service sending me a replacement asap. Thanks!


fast and efficient. went to 3 different rv dealers and 2 parts houses and couldn't find what I needed. got what I needed from etrailer in 4 days. I now know where to go next time.


Product as advertised and delivered when promised

  • How Does LED Clearance Light part # MCL0030ABB Install
    To mount the LED Clearance Light part # MCL0030ABB you would need to pry off the lens using the slots on the bottom of the lens and then use the mounting holes that are behind the lens through the base of the light.

  • Replacement Marker Light For Front Of 2004 Winnebago Rialta Motorhome
    For your 2004 Winnebago Rialta motorhome I recommend going with the LED Clearance or Side Marker Trailer Light w/ Reflector # MCL0030ABB. This light is only 3/8" thick and uses an LED so there is no need to change the bulbs when they go out. It also has a 2 wire pigtail so that you will not have to modify the light to work on your Rialta. The Optronics Clearance or Side Marker Trailer Light # MC68AB that you inquired about will include a incandescent light bulb. It can be mounted on your...

    The closest side marker light we have for those dimensions is the LED Trailer Clearance or Side Marker Light with Reflex Reflector item # 328-K-51. This oval light measures 3-3/4" x 1-5/8" and has mounting holes that are 2-1/2" center to center.

  • 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 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 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.

  • LED Options For Replacing Peterson # 427400 Marker Lights On a Winnebago Rialta
    You are correct the Peterson # 427400 is only offered with an incandescent bulb. You do have the option of replacing your bulbs with some LED Bulbs # ARC68FR and then we also have the Lens # A68AB which can replace any of your cracked lenses. This will save you from having to remove all the lights and install new LEDs like the Optronics # MCL0030ABB.

  • Replacement Trailer Hub/Drum & Self Adjusting Brakes 2016 Sure Trac trailer w/Lippert 5,200LB Axle
    You are able to switch to the Easy Grease Trailer Hub and Drum Assembly # AKHD-655-6-EZ-K from the stock hub your 2016 Sure Trac trailer will have come with. This will switch you from the Outer Bearing # LM67048 and Race # LM67010 your Lippert axle came with to the Outer Bearing # 15123 and Race # 15245. I do recommend upgrading your brakes to the Self-Adjusting # AKEBRK-7-SA over the standard 12" electric brakes you have. These will not require adjustment every 3,000 miles or once you...
