Optronics MCL75 Series LED Marker Clearance Light Diagram

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.

I bought my Haulmark 12'x6' Enclosed trailer used a few months back. The trailer was in good shape but the sun faded out the marker lamps. Since I use the trailer as a landscape equipment trailer I'm usually not working at night but now with the daylight savings hour change I find myself getting home when it's dark and now those faded lamps were bugging me. Since I've had great experience in the past with etrailer.com I decided to take the plunge and change out the 14 marker lights to their LED versions...Wow what a difference. Not only are my lamps no longer sun faded but they are bright! Definitely was worth the money and the installation was quick since they simply snap into place. Thanks, RAM 232009

Oh my, was all a Twitter when they arrived. This was recommended by members from an RV club. I am replacing my old markers with led. First thing I noticed was the wire connection was um, not what I expected, but could work. Then I got your email, sweet. I watched the install video, oh pooh. These snap in a metal bracket, waaah, got no stinking bracket, I be old school, what a twit. So, my question I guess is, can I buy these brackets for this light? I like the snap in place idea, the original is mounted with screws and prone to leaks. It was an oops getting these but, now that I learn more about them, I like them better. 589655

The lamp you purchased needs a mounting bracket like part # A65PB
Black Bracket and Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights
$2.55
in order to be installed. The bracket includes sockets that receive the pins on the back of the lamp. Because there are a number of mounting options and kinds of brackets available, the bracket isnt included with the lamp. If you take a look at the links below, you can see the available brackets that are compatible with this lamp.

The lamp you referenced needs a mounting base as stated in the product description, like part # A65PB
Black Bracket and Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights

. The lamp grounds via the mounting screws, gets 12-volt power from the one wire connecting to the running lamp circuit on the trailer.

Not my first order from etrailer and definitely not my last. My only complaint would be in the packing of small or fragile items loosely in a box with heavier items. One of the trailer light mounts was broken when it got here. No other issues though. 406143

The great thing about etrailer is that when my daughter busted this, I went back in my orders, grabbed the part number, and quickly ordered the replacement. These LED lights replaced the stock on my Harbor Freight trailer and are great unless your daughter uses it as a step. Can't fault the part on that one. 383713

Such an upgrade! My previous leds had one or two in each lamp. These have 4 and being that my trailer hauls my equipment for night work, I am all about visibility! They look great, bright, simple plug and play installation. Loving the mobile Christmas tree effect. Had to overhaul the rear red lighting because they were old bulb markers. All, including my stop/turn/running lights just got converted to leds. No real hassle AT ALL. I honestly felt this company was a bit pricey but you can tell as soon as you open the box they are grade A lighting. Fast and professional service! 323884

Do you have a question about this Trailer Light?


  • What is Difference between Miro Flex and Thin Line Optronics Clearance Lights
  • The Miro-Flex part # MCL63AB and the Thin Line part # MCL75AB are both very similar. They essentially are just visual differences for the lens. The Miro Flex has more of a Euro style look where you can see the diodes and the reflective base in the light whereas the Thin Line has the diodes obscured. Both would work well and I would recommend you pick which you like the appearance of more.

  • Replacing Existing Marker Lights on 2012 Haulmark Race Trailer with LEDs
  • You can certainly replace your existing incandescent marker/clearance lamps with LED models. LEDs have many advantages over incandescent lamps. They have a much longer life, they draw a fraction of the amperage and are brighter. The Optronics LED Clearance and Side Marker Light you mentioned, part # MCL75AB uses a chrome # A67CB or black # A65PB mounting bracket. The lamp is fully waterproof. If you are looking for something that is a close replacement for your existing lights, I...

  • Clearance Light Replacement Recommendation for TruckLite Model 19

  • Is a Base Required for Mounting the # MCL63AB and # MCL75AB Trailer Side Marker Lights
  • Yes, a mounting base is necessary for the # MCL63AB, you will need to use either the Black Bracket and Single Wire Plug, item # A65PB, or the Chrome Bracket and Single Wire Plug, item # A67CB with this light. The # MCL75AB, Thin Line Trailer lights also require a mounting base. Brackets for the # MCL75AB include the # A65PB and the # A67CB bases, mentioned for the # MCL63AB light.

  • Can Optronics Thin Line LED Trailer Clearance Lights Fit Base Of Lights On Snowmobile Trailer
  • I was not able to find the truck Lite 2303 or 2294 lights on their website. You may want to consider replacing most if not all of the incandescent lights on your snowmobile trailer. Since LEDs draw about 1/10 of the power, you can certainly get the draw down a lot more than what you are doing now. We do not have a converter box for a 10-amp load as you described. The # MCL75RB and # MCL75AB lights measure 3-15/16 inches L x 1-1/4 inches W x 7/8 inch D. and require the black base,...

  • How to Ground an LED Trailer Light to a Trailer with a Fiberglass Body
  • What you would need to do is run a jumper ground from the grounding point on light # MCL75AB to a metal location nearby. You can use the frame or a metal support structure if available. This may require some additional work because you will have to route a wire somewhere for the ground but it will work out just fine.

  • Would Sealed Thin Clearance Lights part # MCL75AB Fit a Horse Trailer
  • The Sealed Thin Clearance Lights part # MCL75AB that you referenced would work great for you. They have a universal style installation so they would work well. You will need a mounting bracket for these though. For that you would want the part # A65PB. I attached an install video for this light for you to check out as well.

  • Power Draw of Optronics Trailer Clearance/ Marker Light # MC65AB
  • According to my Optronics representative, the Optronics Sealed Trailer Clearance and Marker Light, part # MC65AB draws a total of 0.6 amps at 12.8-volts. An LED version is also available, part # MCL75AB which draws a fraction of that, 0.06 amps at 12.8-volts. Either lamp is used with a base, part # A65PB in black or # A67CB in chrome plated plastic. The lamp base has a single power wire, and picks up its grounding connection by its mounting hardware being connected directly to the trailer frame.
