Optronics MCL67AB ThinLine LED Clearance Marker 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.


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.

  • How is Power and Ground Ran to A Trailer Light with a Single Wire
    Hey B, so any time clearance lights use a single wire for install that wire is the power wire and the light itself grounds through the mounting hardware. If the mounting location is not a suitable ground you can run a ground wire to the mounting hardware and that will complete the circuit. Does that make sense?

  • Why Does a Marker or Clearance Light Only Have One Wire
    The marker and clearance lights you have now ground with a single wire hence why you have two wires total, one for power and one for ground. If the marker or clearance light only has one wire then this wire is for power and the light grounds though the mounting hardware. When you determine which of the two wires you have is for power, you just simply need to cap the other one off. If the new light with only one wire is installed in a rubber grommet then you will need to run a ground wire...

  • Recommended Replacement Clearance Lights With Only Wire
    It's normal for some clearance lights to ground through the mounting screw instead of running an extra wire so there's nothing wrong with that. For the amber clearance lights you can use part # MCL67AB and for the red part # MCL67RB. These both come with a single wire for power and ground the the bracket mount screw and are 4-1/8" long x 1-1/4" tall x 1-3/16" deep.

  • Troubleshooting 2 Wire Trailer Taillights That Dont Work Installed in Place of Single Wire Lights
    If you had single wire trailer taillights initially that meant that the assemblies grounded through the mounting hardware. If you went to a two wire light that would mean you would actually have to ground each of the assemblies using the white wire of them. You can run them back to the mounting hardware of the lights or you can run them to the main ground harness of your trailer and they should work again. You might also check to make sure that the main ground of your trailer didn't get...

  • How to Wire 2-Wire Trailer Clearance Lamp
    Your old trailer lights like # MCL67AB are grounded to the trailer via their mounting hardware. Since your new lamps use 2 wires, you'll connect the red wire to the trailer running lamp circuit and install a ring terminal on the end of the black wire. You'll ground the black wire to the trailer frame using a self-tapping screw, and the lamp will work perfectly for you. If you click the provided link, you can see my friend Shane completing an installation of a 2-wire trailer clearance lamp.

  • How Does Light with 1 Wire Ground
    When a single function light only has 1 wire, like the Thinline LED Trailer Clearance or Side Marker Light # MCL67AB, it means that it grounds through the mounting hardware. If the mounting location doesn't have a clean, bare-metal surface then you either need to clean it for a good ground connection or find an over head light that uses 2 wires for installation.

  • Can Ground Wire Be Attached To Optronics Trailer Light When Installing
    If you wish to attach all of your lights to one dedicated ground wire that will work fine for you. Please be aware that modifying the mount in any manner will void the warranty for the light. The # MCL67AB light is designed to be grounded through the mounting hardware. You will want to make sure you do not damage the light base when soldering a ground wire.

  • Grounding Side Marker Lights with 1 Wire
    If your side marker lights use 1 wire like the Thinline LED Trailer Clearance or Side Marker Light # MCL67AB then you actually won't route a ground wire to them as they will ground through the mounting hardware. If you are finding a way to attached your white ground wire to these lights that only have 1 wire then that could very well be your problem. Just make sure that the 1 wire is connected to your running light circuit and that they are connected to a clean, bare-metal surface for...

  • Replacement Side Marker Light for Wesbar 203260 on Boat Trailer
    To replace the Wesbar 203260 side lights on your trailer, I recommend looking at the Optronics Thinline Trailer Clearance or Side Marker Light # MCL67AB. This light measures 4-1/8 inches long x 1-1/4 inches wide x 1-3/16 inches deep, which is similar to the dimensions on the Wesbar model which is, as you mentioned, no longer in production. The LED lights will also provide a nice upgrade over the original bulbs. LEDs are brighter, draw a fraction of the power and will last much longer than...

  • What Hardware Is Needed To Install the Thinline LED Trailer Clearance or Side Marker Light MCL67AB
    The Thinline LED Trailer Clearance or Side Marker Light part # MCL67AB is a surface mount light that has two mounting holes which you will see once the lens is removed. In order to mount this you can use pretty much any self tapping-screw like the Self-Tapping Phillips Head Screw part # 1131832. The Self-Tapping Phillips Head Screw could be used to mount most of our trailer side marker/clearance lights.

  • Replacement Marker Light for My Wesbar 203260

  • Replacement Clearance Lights For A 1987 5th Wheel Camper
    To find the proper bulb for your 1987 5th Wheel Camper you would need to know what brand of light you currently have. For example The Replacement # 67 Bulb for Trailer Lights, License Plate Lights, and Utility Lights # 67 will replace a number 67 bulb. I would recommend getting a whole new clearance light.

  • Troubleshooting New Trailer LED Side Markers Not Working
    The issue you are having still sounds like there might be a weak or bad ground on the new LED lights. The mix between them and the incandescent assemblies at the rear of the trailer should not be causing this problem so it has to be something specific with the new lights that were installed. Many LED trailer lights feature a 2 wire design (one for ground and one for power) and don't actually use the mounting hardware for its ground like with your old assemblies. If the new lights have...

  • Replacement Clearance Light for 1999 EZ Loader Boat Trailer
    According to Wesbar, the lamp you specified was discontinued about 5 years ago. We have several clearance/marker lights that would work for you, but one of the closest to the 4-3/4 x 1-7/16 x 1-1/4 inch size of the original lamps is part # MCL67AB from Optronics. Instead of bulbs, the lamp uses LED's, which are brighter than incandescent bulbs, but draw a fraction of the power. The lamp measures 3-15/16 in length, 1-1/4 inches height and 7/8 of an inch deep.

  • Wall Adapter Compatibility with 12 Volt Clearance Light
    SInce it has a single wire, it is a clearance light. You will use the mounting bracket as your ground as you stated and run 12v power to the wire. You can use a 12v marine battery connecting the negative to the bracket and the positive to the wire. If you want to install a switch like # PK34513 in line that will work well. You can use wire like the 14 Gauge Primary Wire - Yellow - per Foot # DW02412-1. If you want a converter, you can use the # 329-GENIUS2D to connect to a standard...
