dimensions of light

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.

Ask the Experts about this Optronics Trailer Lights

  • Replacement Optronics LED Trailer Marker Lights with Single Mounting Stud
    It sounds like you are looking for the Optronics Sealed, Mini Rectangular LED Trailer Clearance Light # MCL95RB in Red and # MCL95AB for Amber. These sealed, waterproof LED light assemblies measure 2-1/8 inches long and 1-1/8 inches wide. They feature a single mounting stud on the back. These do have a single wire design, as opposed to the 2-wire design you mentioned. This simply means that they will ground through the mounting stud instead of using a dedicated ground wire. I have attached...

  • Can a Stainless Steel Stud be Used as the Ground Stud on Optronics LED Clearance Light
    Using stainless steel instead of regular steel for the stud on clearance light # MCL95RB would be fine. But what you can do to help the ground is attach a wire with ring terminal between the stud and where it makes contact with the trailer frame and then run the other end of that wire to the main trailer connector ground location. And if that doesn't work then there may be something internally wrong with the light.

  • Rewiring Boat Trailer for 7-Way to Use LED Lights
    There are a number of things you will need if you want to re-wire your boat trailer to use LED lights and you should start with the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141. Keep in mind you will also need Ring Terminals # 44-5310A and Loom Clamps # A0500 The box is color coded like this: - White (ground): 10 gauge - Black (12V power): 10 gauge - Yellow (reverse/auxiliary): 14 gauge - Red (left turn and stop): 14 gauge - Green (tail and running lights):...

  • Replacement Trailer Lights for Shoreland'r Boat Trailer
    For other options we have # MCL95AB for amber lights and # MCL95RB for red. They're still surface mounted lights but the base is included and may work for you. They're also a single wire design so they ground through the mounting hardware. If these will not work for you reply to my email with your pictures and dimensions and I'll see if I can find some that will.

  • 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....

    We have couple of different light options for you, but the Optronics Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Light, Ear Mount, 3 Diode - Amber # MCL85AB is not available in red. One red clearance light option we carry is the Optronics Sealed, Mini LED Side Marker, Clearance or Identification Light, 1 Wire, 2 Diode - Red # MCL131R2B.

  • Are Mounting Brackets Available for Optronics Mini LED Clearance Lights # MCL95AB and # MCL95RB
    The Optronics Mini Rectangular LED Clearance Lights, # MCL95AB and # MCL95RB, are single stud surface mount lights, so they do not have a grommet or mounting bracket available. They were designed to mount directly to an existing bracket or to the trailer frame. The closest clearance lights that we carry to the dimensions of your current lights are the Optronics Square LED Clearance Light, # MCL36AB and # MCL36RB. These are also single stud surface mount lights, but the larger size should...

  • Replacement LED Trailer Lights for a 2000 Ranger R71 Boat Trailer
    I would love to help you upgrade to LED lights on your trailer but unfortunately, trailer manufacturers don't just give us a list with every light on the trailer for situations like this. If you can provide me with your full 17 digit VIN I would be more than glad to call on your behalf and see if we have the correct replacements for you.

  • Should Whole Light Bar # MCL97RPG be Replaced if One Light is Out
    Light # MCL95RB would not fit light bar # MCL97RPG because it does not mount appropriately to attach to the light bar base. If it were me I would replace the hole light bar. Since yours is riveted on those rivets will have to be drilled out and replaced with regular screws or bolts and nuts. All of the 2 x 1 inch lights are stud mount, see link, so keep that in mind when looking for replacements.

  • Bearing Kit for 3,500 lb Trailer Axle and LED Clearance Light for Pace Utility Trailer
    The thickness is right at 1/8 of an inch for the mounting plate of the spare carrier part # FSTC1000301. For the LED version of the light in your picture you would want the part # AL91RB. Or part # MCL95RB for a version of the light that includes a base. The correct bearing kit for a 3,500 lb trailer axle is the part # BK2-100.

  • 1141 LED Light for Interior of Horse Trailer
    For a soft white LED that fits a 1141 socket which would work great for interior lighting you would want the part # AR50367. The clearance lights # MCL95RB and # MCL95AB would work great for clearance light replacements as well.

  • Troubleshooting Trailer Running Lights Not Working
    There are a number of potential issues that could be causing your running lights not to work, but you will have to troubleshoot the problem with some detail. The first thing to do is take a look at your vehicle's owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific problem you will need to purchase a circuit tester if you do not have one - the very handy Cordless Circuit Tester # PTW2979...

  • Solution for Wesbar Clearance Light # W003239 With Blown Bulb
    Replacement bulbs for the # W003239 aren't available, but for the price you may as well just replace the entire thing. For basically the same light at a lower price the part # MC95RB would be an exact replacement. Or if you wanted to never worry about replacing the bulb again you could go with the LED version part # MCL95RB. LEDs basically never wear out and they are incredibly bright.

  • After Installing LED Trailer Tail and Clearance Lights Only Turn Signals Work
    It is not likely that the clearance lights, # MCL95RB, are the issue since they ground through the mounting hardware and only have one power wire that goes to the running light circuit. Still it is worth checking to make sure that the grounds are attached to clean and corrosion free bare metal surfaces. On the tail lights, # STL70RB, the red wire is for brake lights and turn signal, black is for running lights. And white is the ground. You can't always go by color, you have to go by...

  • Availability of Clearance Light for Trailer that Uses a Power and a Ground Light
    You could use the part # MCL95RB with a ground wire if you wanted to. All you would need to do is run the ground wire to the mounting stud of the light before you tighten it down. Or the part # MCL13R2B is a somewhat similar light that uses two wire for power and ground. It is also submersible.
