Optronics MC55 Series Marker Clearance Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Video Transcript for Checking Out the Optronics Clearance and Side Marker Trailer Light

Today we are going to take a look at Optronics sealed 2-1/2 inch round trailer clearance and side marker light, part number MC55RB. The lens of this light is sealed and waterproofed against the housing and inside is a heavy-duty long life bulb. This light will require a mounting grommet and plug to complete the installation. Next we are going to hook up a power supply to the light so you can see how it looks. We will connect our ground wire to one of the contact points and our power wire to the other. Next we will turn off our overhead lights so you can see how bright the light is. And that does it for Optronics sealed 2-1/2 inch round trailer clearance and side marker light, part number MC55RB.

  • 1990 Big Foot Slide Truck Camper Replacement Red and Amber Clearance Lights
    The red light part # MC55RB would be a 2-1/2 inch diameter light that would work well for the red lights you need to replace. For the amber version you would want the # MC55AB. The grommet needed is the part # A55GB. For a pigtail harness you would want the part # A46PB. This comes with a ground and power wire. You would need to route the white wire to a ground wire since your trailer is made of fiberglass. The black wire is the power wire. The grommet requires a 3 inch hole to be drilled...

  • Replacement 2-1/2 Inch Round Marker Light on Triton Trailers Elite WCII Personal Watercraft Trailer
    I do not have a cross reference chart for Truck-Lite trailer lights, but we have several 2-1/2 inch round clearance lights that may work for you. I have attached a link that will take you to all of our 2 inch and 2-1/2 inch round trailer lights for you to check out. I have also linked a few LED and incandescent 2-1/2 inch round clearance lights for you to checkout below. The biggest difference between many of these lights is the depth of the lens. Most of the lights are either 11/16 inches...

  • Replacement Boat Trailer Lights for 2-3/4" Rough Cutout and 2-1/4" Grommet
    I have a solution for you, but we do not have any replacement lights that will fit in those grommets. Instead, you can use the LED Clearance or Side Marker Light # MCL002AXB (amber) and # MCL002RXB, which require a rough cutout dimension of 2-3/4", so they'll fit in your existing holes and provide you with the light solution you're looking for. These are waterproof LED lights so they're the perfect solution for a boat trailer as long as the rest of your lights are already LED. If your...

  • Can a 2-1/2 Inch Round Surface Mount Trailer Light be Mounted Using a Grommet Instead
    Technically you could use grommet # A57GB with trailer light # MC58RB. However the light was meant to be attached to a flat surface. The recessed mount version is # MC55RB and you would use grommet # A55GB. This set up actually costs a little less though the light requires pigtail # A46PB.

  • Wiring Pigtail Recommendation for a Trailer Clearance Light MC55RB
    The Trailer Light part # MC55RB that you referenced uses the connector part # A46PB as a pig tail harness. You would just plug the harness into the light and then run the power to the black wire and the ground to the white wire and you would be good to go.
