Optronics MCL11 Series Uni-Lite LED Marker Clearance Light Dimensions

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 circuit board is sealed, which means that water will not 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 a side marker light.

I have finally finished the install of the great products that I’ve purchased from Etrailer. Curt 24K 5th wheel hitch, the lube discs, the front receiver hitch tube, the Factory 7-way connector and 7 -way extension (I have 3 7-way plugs on my truck) and the countless number of LED lights. The service is amazing and the customer service I received was fabulous. I really like these folks as they were vary knowledgeable about what I was after and pointed me in the right direction to accomplish my end goal. Thanks to everyone at Etrailer. I couldn’t have done it all without you.

Everything I’ve done to my truck with multiple products from Etrailer has just been perfect. All working and performing as expected. Couldn’t have ask for more reliable products than those I’ve installed.

Great little running light puck! Easy to install and very bright at night and is even very visible in daylight. Only about an inch in diameter on the outside, you wouldn't think it was much larger from the amount of light they provide.

Awesome, bright lights. They really blend in well in daylight but stand out at night.
Joseph C - 12/29/2020


Very well built, sturdy and totally sealed against moisture. I installed these into the top of my Haulmark enclosed trailer to act as clearance lights. Installation was a breeze, I just drilled a 3/4" hole with a step bit, wired all five lights together and tied it into the running lights of the trailer's harness. I put the ground against the steel frame. I went a step further and put a bead of clear marine grade silicone around the light to ensure no moisture makes it inside the trailer despite these being a tight fit. As you can see from the pictures, installation is clean and they're very bright, both day and night! I put one on either end, 6" from the sides and the three middles ones are spaced 10" apart. Similar to the clearance lights on a truck, I didn't use a template, just winged it.


I have purchased lights from etrailer several times and the service and quality have been great. I have purchased lights for my truck and also have used there submersible lights for my boat trailer.
lights have been in service for over a year and still bright as the first day I installed them.


Shipping was slow, but I can't complain much considering it was free!

I chopped the fenders on my 2008 Jeep Wrangler, which involved removing the side marker lights. I installed a pair of these DOT approved lights to meet inspection requirements.

As for the lights, they are well-constructed and very bright. Installation was difficult; even after drilling and deburring a 11/16" hole, the grommet barely fit in. I had to put a small amount of grease on the light's lateral surfaces before the light would slide into the grommets.

Overall, I am very pleased with the product. Poison Spyder sells an inferior product at several times the price; I am glad I found these here!


Awesome little light! Very bright! Fits snug in a 3/4" hole. These worked perfectly for my running light project on the air dam. Ordered these on a Sunday, they were at my door on Thursday. Excellent customer service Etrailer! (Side note, the lights behind the grill are 4" round, not the 3/4")


I love these lights. They compliment the other leds on my truck and camper. I installed these on the lower front air dam.


Great lights very bright, really like the size and shape of these lights and the fact that they are clear lenses and they match my complete clear trailer light set up


The lights I ordered are very bright and seem to be well assembled. I will be continuing to use etrailer for my lights


Great service. Product was just as expected. Install looks excellent on the front of my truck.

Do these lights match the Ford 150 Orange running lights? Im looking to do the same thing with the lights like you did. Thanks for any input
-- comment by: mark p - 04/15/2014
Yes, these do match the OE orange marker lights. The color is just about identical in my opinion. I was going for a very clean look and these worked great. I have a few additional pics on the following forum if you are interested.

Awesome little light, I put that s**t on everything.


Awesome product! Very bright and easy i nstallation!


The LED lights I purchased a year ago are still functioning well. I used these small clear amber lights as marker/clearance lights around my trailer I pull with my motorcycle. Anyone looking to make your trailer highly visible on the road should have these. Lights are easy to install and wire in.


I have purchased several items from etrailer and recommend all of them and the folks at etrailer.
Items purchased by part #: 9653P; BK-70BB; 2118-605-04; 98174LED; PK12706; MCL11AKB; H20046.

Shipped well packaged. All items are accurately described and are fully functional. etrailer videos are a big help and their staff is knowledgeable!


My customer requested an extended light to keep track of battery voltage. I interfaced the Uni-Lite LED to our LCD-HV Low Battery Alarm and when the voltage dropped at the set point the light came on this was a great warning of low voltage. The light was extra bright and can be seen from a good distant. Very happy with the results of brightness and ease of connections.


Great lights! Nice and bright. Had them on the truck for a year now and no issues.


Super bright and very easy to install.


I have ordered from Etrailer for several years, had a small problem on this order. They rectified the issue easily and quickly. Highly recommend Etrailer and their customer service team.


The lights are easily fitted when drilling the proper size hole. Just push, and it'll snap. They illuminate a fair and enough amount of light for their small size! I recommend these lights to be installed as marker lights.


Nice lights fast shipping excellent ser vice


These little beauties are awesome! I am using them for small surface mounted turn signals for a "show" motor scooter... Theses little lights are bright and extremely compact which I love! The quality is actually much higher than I anticipated which was a great surprise I almost figured these could've been "throw away every year"'type of lights. But they most definitely are not! Great product for my application for sure


I think these lights are going to work great on my boat trailer, I am painting trailer and thought I would give the lighting an upgrade. Thanks, Very good service


Easy to install. I used them for marker lights on my boat trailer. LEDs are very bright with very low power requirements. I would buy again.


3/4 inch led marker lights-received super fast-reasonable price!
Will definitely use trailer again.


I replaced all oem lights on my boat trailer with LED's, easy to install and still burning bright today.

  • Will Uni-Lite Mini LED Light Work On Motorcycle As Turn Signal
    You should have no problem using the Uni-Lite Mini LED Side Marker/Clearance Light, part # MCL11CAKB, on your motorcycle. You will need to locate the wire that leads to your existing turn signals. Then make sure you attach the white wire to a bare metal surface for the ground. All you need to do then is attach the black wire to the power wire that is going to your existing turn signals and you should be ready to go. I have attached a product review video for this light you can check...

  • Wiring Optronics Uni-Lite Clearance Lights on a Motorcycle for Additional Turn Signals
    You can tap the power wire from the Uni-Lite, # MCL11CAKB, to the factory turn signal wire but you will still need to ground the light as well. You can try using an existing ground for another light but in the event that does not work you will need to ground the light to the metal frame.

  • Length of Wire Leads on Optronics Uni-Lite Mini LED Side Marker/Clearance Light # MCL11CAKB
    I pulled one of the # MCL11CAKB lamps from the warehouse and measured the wire leads for you. The distance from the rear of the lamp to the tip of the wires is exactly 7-1/2 inches.

  • Optronics MCL11CAKB Marker Light Wire Gauge and Panel Thickness
    I just went out to the warehouse and took a look at the Uni-Lite LED Clearance and Side Marker Light w Grommet - Submersible - 2 Diodes - Clear Lens - Amber item # MCL11CAKB. It uses 18 gauge wire and the panel thickness is 5/8".

  • Can a Dimmer be Put on Uni-Lite Mini LED Side Marker/Clearance Light # MCL11CAKB
    LED lights use such little power, 0.047 amps for # MCL11CAKB, that it might be difficult to be able to put a dimmer of any kind on it. If you can find a dimmer that works at the milliamp level then it could work. This light can be used as a clearance light, as can the red version # MCL11RKB but they are not DOT approved as trailer brake lights.

  • Availability of a Small Round Trailer Clearance Light with a Clear Lens and Amber Light
    We do have a light that is a very close match to # MCL11AKB except with a clear lens and amber light. Take a look at the Sealed, Uni-Lite Mini LED Side Marker/Clearance Light, # MCL11CAKB. This light is just a little larger than the one you referenced but does have a clear lens and amber light.

  • Wiring Uni-Lite Mini LED Side Marker/Clearance Lights as Turn Signals Only on a Trailer
    The only issue you are going to have with using the Uni-Lite Mini LED Side Marker/Clearance Light # MCL11CAKB is that on a trailer, the brake lights and turn signals are combined on the same circuit. So when you step on the brakes these lights will light up as well. In order to prevent that from happening you will need to use a special converter to separate out the brake light and turn signals. You would split off the turn signal and brake wire to go to each new light. You would attach...

  • Replacement Front Marker Light for 195 R-Pod
    It is difficult to say exactly based on that picture. It looks like the light has some sort of gold paint over it. The # MCL11CAKB doesn't have the same round top to it that your current light has but it would work. A better option would probably be the # MCL10AKB. This is closer in design and also has an amber lens. Both of them have a 3/4" diameter, both would make a good replacement.

  • Lumens Rating of LED Bullet Utility Light with Grommet
    I reached out to Command about the LED Bullet Utility Light with Grommet part # 328-003-183CW but they were not able to provide a lumen rating. However, we do have the Uni-Lite LED Clearance and Side Marker Light w Grommet part # MCL11CAKB which I do have a lumen rating for of 35. The Uni-Lite LED Clearance and Side Marker Light w Grommet has two diodes so it will be twice as bright as the Command about the LED Bullet Utility Light with Grommet.

  • Clear Submersible LED Trailer Light Recommendation
    For a similar LED light as the CIPA EVO light part # CM93236 that you referenced that is submersible and would be great for a boat trailer I would recommend the Uni-Lite Mini LED Side Marker/Clearance Light w/ Grommet part # MCL11CAKB. This is flush mount light. Another option that is a surface mount would be the Sealed, Mini LED Marker, Clearance or Identification Light # MCL13CR2B. The # CM93236 is designed to fit into a vehicle bulb socket, so not only would it not be submersible it...

  • Clearance Light with Turning Signal Function for Running Boards
    I do have a solution for you but there is no way to wire the Uni-Lite LED Clearance and Side Marker Light w Grommet # MCL11CAKB so that it stays on with your clearance lights but then also acts as a turn signal when your headlights are on. You can connect it to both functions and use a single park diode like part # RM-690 but you would only see the turn signal when your headlights are off. For your application the only option we have available is the GloLight Uni-Lite LED Clearance or...

  • Wiring for Clearance and Turn Signal Functions with Clear Lens 2 Wire LED Light
    The GloLight Uni-Lite LED Clearance or Side Marker Light with Grommet - Turn - Round - Amber Lens # MCL121AK9PVG will work as both a clearance light as well as a turn signal. The Uni-Lite LED Clearance and Side Marker Light w Grommet - Submersible - 2 Diodes - Clear Lens - Amber # MCL11CAKB you pointed out is the closest to that light with the dual function in a clear lens. We unfortunately do not have the 3 wire light with the clear lens you are seeking. To get the features you are...

  • Troubleshooting Optronics Uni-Lite LED Clearance and Side Marker Light Not Coming On with Aux Switch
    I recommend double checking your wiring for the lights. A load resistor will not be needed since the # MCL11CAKB lights are not blinking. A load resistor is designed for use when an LED is hyperflashing when used as a turn signal. You will want to run a wire from the positive terminal on the vehicle battery to the auxiliary switch, then from the switch to the first light, from the first light to the second lights, so on and so forth. The easiest way to connect all of the lights to a power...

  • Availability of LED Back-Up Lamp for 2-1/2 Inch Rough Opening
    If you can very slightly enlarge the hole so it's 2-5/16 inches in diameter, I have a grommet mount lamp that will work great for you. The # UCL50CB LED lamp would use the # A54GB grommet and the # A46PB wiring pigtail. The lamp isn't considered a back-up lamp, but unless the vehicle in question is a commercial vehicle that's subject to DOT inspections, it'll work great for you.
