Optronics Thinline MCL75 Series Red LED 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.


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.

Here we have Optronics sealed, thin line LED trailer clearance and side marker light, part number MCL75RB. This light has a lens that is sealed and waterproofed against the housing. Inside are four LEDs that draw a total of 0.06 amps at 12.8 volts. It is designed to mount using a bracket that will connect your ground and electrical connections. The bracket is designed to surface mount to the trailer using mounting holes that are three inches on center. Next we will hook the light up to a power supply so you can see how it looks. We will connect one of the posts on the back to a ground connection and the other to power. Next we will turn off the overhead lights so you can see how bright the light is. And that does it for Optronics sealed, thin line LED trailer clearance light, part number MCL75RB.

I bought the series of thin line replacement lights for my 2005 Haulmark trailer. They fit and worked perfectly, are as visible as the originals (with restored color as well - the old ones were sun-faded) while drawing much less power. Now the 5 amp fuse that most cars have for a tail light will safely run all of the tail, clearance, and interior lights on the trailer without blowing the fuse. The first time I plugged in the trailer with the original lights it blew the fuse (without even the interior lights on). Buying these lights was the perfect solution. Now any flat 4-wire plug on any car can be used to operate the trailer. 109589

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 232011

Excellent products. These lights work perfectly, are rugged and seem to last. The license plate lights are super bright so law enforcement have no problem reading the plate which avoids unnecessary stops. The lights are directs replacements as well so no modifications needed.

Wow, what a difference LED clearance lights make, especially at night. It makes my business information really stand out and people who follow me really notice that. I've been wanting to go LED the past couple years and now that I recently made the change, I'm not ever going back to standard low-level light bulbs again. Thanks etrailer for offering these lights and at a very affordable price. You were almost half the price as our local part store was selling them for, plus these are more stylish as well. 449123

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. 406144
