Optronics MC38 Series Incandescent Red Marker Clearance Light Dimensions

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.

  • How to Find Replacement Lens for Trailer Identification Light Bar
    The numbers you provided indicate that the lens meets DOT requirements, but it's unfortunately not a unique number that will help us identify the lamp in order to find a replacement lens. Many manufacturers print, stamp or sticker the number of the lamp somewhere on its housing. If you could find THAT number, it would likely help in finding your lens. If you could reply with a part number for the lamp or a photo (which would be really helpful), I'd be happy to check into it further for...

  • Red and Amber Clearance Replacement Lights for Signal Strat 77-557
    From what I could find online it looks like your Signal Stat 77-557 side markers are 4 x 2. We have some options from Optronics for you that have replacement bulbs and lens available. For Amber # MC38AB - Replacement Lens is # A38AB For Red # MC38RB - Replacement Lens is # A38RB They both use the same replacement light bulb which can be found on our site using part # A194B.

  • Finding Replacement Lens for Command SAE-AP2-91 Light on Jayco Camper
    The SAE number found on the existing lens for your Jayco popup camper refers to the lens/light rating and not to the actual part number. I recommend measuring the dimensions of the clearance light you have and then try to find the best possible match for a replacement lens. The Bargman Clearance Light Replacement Lens # 34-59-010 referenced in your question is 4 inches in length x 2 inches wide x 5/8 inches in height. For an oval shape with similar dimensions, I recommend looking at the...

  • Finding the Correct Replacement Tail Light Lens for a 2004 Fleetwood Sequoia Pop Up Camper
    You will need to pull a light housing and look for any identification that will tell you the manufacturer and model number. With that information I can determine if there is a replacement that will fit. Otherwise you will have to go by the measurements. Lens # A38RB that you referenced fits light # MC38RB. This light measures 4 inches long, 2-1/16 inches tall, and 1-5/32 inches deep. The # A32RB that you have already tried will fit light # MC32RB which measures 4 inches long, 2 inches...

  • Replacement Lens for Peterson Trailer Light 106R
    I pulled up pictures of the Peterson Light part 106R and was able to determine that the part # 108-15R would fit it as a replacement lens. For an Optronics equivalent for the entire light you would need the part # MC38RB.

  • Are 4" Oval Peterson and Optronics Clearance Lights the Same Dimensions
    They are not the exact same shape but they basically have the same dimensions with the differences being within 1/16" of each other (which could be the difference between manufacturer's preference for measurements). For the amber version of the Peterson Light # 423000 you need part # 422800 and for the red version of the Optronics Light # MC38AB you need part # MC38RB. Either way thought these lights are interchangeable with each other.

  • One Wire Clearance and Side Marker Light Options to Replace Lights on Horton Hauler Trailer
    We have quite a few different options for trailer clearance lights with one wire and that will ground through the mounting hardware. These lights come in various sizes and shapes. The best replacement for your trailer will depend on the size light you are wanting to replace. For a small LED clearance light that is a stud-mount, you can use the Optronics Sealed Mini Rectangular LED Stud Mount Trailer Clearance Light. For an amber light you will want # MCL95AB and for a red light # MCL95RB....

  • Replacement Multi-Purpose Locking T-Handle
    Yes, we do have locking t-handles. I recommend the Bauer Products T-Handle Lock for Truck Caps item # BA47VR. This t-handle is 3-1/2" long x 2" wide, the length of shaft is 2", and the distance between mounting holes center to center is 1-1/2".

  • Most Popular Replacement Clearance/Marker Lights for an Old Travel Trailer
    The most popular clearance/marker lights we offer are the Optronics Clearance or Side Marker Lights w/ Reflex Reflector. These are offered in both incandescent part # MC38AB for amber or part # MC38RB for red and LED part # MCL31AB for amber or part # MCL31RB for red. They have a two wire design so they are super easy to install. The white wire gets grounded and then the back wire goes to the running light circuit with butt connectors part # DW05744-5. If you need screws to attach the light...

  • Replacement Red Reflector Lens For Rear Running Light That Measures 3-3/4 X 1-3/4
    The closest we can come to this size is the Replacement Red Lens for Peterson Oval Clearance or Side Marker Light w/ Reflector, part # 108-15R. This replacement lens measures 3-3/4" wide X 1-5/8" tall. I cannot guarantee this replacement lens will fit your rear running light that measures 3-3/4" wide X 1-3/4" tall. You can always replace the entire light with the Optronics Trailer Clearance or Side Marker Light w/ Reflector - Incandescent - Oval - Red Lens, part # MC38RB. I have included...
