P2-Rated Lights
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.

A good replacement for the old bulb Clearance lights.
by: Ed07/14/2021
My two year old yacht club trailer side marker lights had a mind of their own and would inadvertently decide to energize or not. The bulbs could not be replaced as these were a one piece unit.I ordered two LED marker lights from etrailer and after replacing the incandescent fixtures I haven't had an issue. I predict my rear lights being next.
by: Joe09/03/2018
This is a nice quality light and the LED aspect of it is sweet. I am holding back a star because the black wire that powers the light is ridiculously short. If you are running the light out on a fender, you have to split your wire harness and send the brown wire to it. If the manufacturer had spent another one tenth of a cent and made the black wire longer, it would have been better. Also, the back of the light, the grooves for the wire are a bit shallow. Difficult to get the light to sit properly. Once it's up and running it's quite sharp.

Easy to install and wire on my basic 5'x8' utility trailer, great product for the price.

exact replacement. thank you

Excellent lights. Replaced old broken incandescent lights with these LED light. Quick easy replacement.

Nice bright L.E.D. clearance lights.
Low drain on your battery.
Works great on the golf cart I am refurbishing.

Just what I needed and speedy delivery!

After one year of use all LED lights work flawlessly. They were an exact replacement for original. Can't be more pleased with the product and etrailer company!

Just what I needed and very quick to sh ip.
by: Joel L.08/12/2014
I got fed up with the bulbs losing contact in the stock clearance lights that came installed on my trailer. These were the solution. The LEDs should last a good long time and vibration won't be an issue. They are plenty bright enough as far as I'm concerned. As inexpensive as they are, they still seem to be fairly well made. A couple of self-drilling screws for the ground leads, a couple of crimp connectors and some heat shrink tubing for the power leads were all I needed to complete the swap. I'm totally satisfied. If these lights fit your application, buy them.

Still rock solid after a year installed.

This is the expedition trailer you helped me build............Thanks.
by: Jim12/10/2017
Installed this and several other lights on a new trailer. Factory lighting and wiring left a lot to be desired, and with the help of etrailer.com I was able to get everything fixed up like I wanted.
Lights work very well - clear and bright yellow clearance markers.

All of the products I purchased its been about 2 years now are still working great. Thanks for checking in.
by: Eddie K06/09/2015
Very easy to install with the center post / bolt just like the marker lights I was replacing, Just had to add a ground (drill a hole to attach the ground wire to the frame). This is an extremely bright led- way brighter than the incandescent one I replaced and hopefully will last the life of the trailer (no more bulbs to replace!)

These led lights are a great upgrade on my car hauler. E Trailer's price is far less than any other site I found. Staff very friendly and willing to you find what you need.

Its been a year and they are still going strong.
by: Rick R.01/14/2018
Replaced all of the lights on my utility trailer, whose incondescent bulbs were constantly breaking, with LED lights and fixtures. The LED lights are bright and dependable. The onboard computer senses when the trailer is attached and works fine with the LEDs. I'm very pleased that I made this switch and with the parts provided by etrailer.com. Good quality parts at reasonable prices.
by: William Shreeve11/22/2014
These lights were replacements for bulb-type clearance lights on a 4' by 8' utility trailer. The original lights were OK but beat up by string trimmers over the years.
These lights were an exact fit and installed perfectly. They are at least twice as bright as the originals. When the time comes to replace the tail lights, I will go with LEDs as well.
The most time consuming part of installation was trying to find my wire splicing hardware (cable-to-cable connectors) and I would suggest you bundle these with the lights for convenience.
by: David11/13/2018
6 LED marker lights perfect upgrade for my 2004 utility trailer replacing factory incandescent bulbs. Much easier to see trailer when pulling and backing at night. Much safer for others to quickly spot my trailer in bad weather conditions... much BRIGHTER !
Unlike others manufacturers, there is more than enough wire to allow easy soldering along with a ring terminal which guarantees a perfect ground to trailer.
Always quick shipping

Side amber light was delivered correctly and in a speedy manner. It matched perfectly the damaged light on my trailer. Thank you for your excellent service.

It has hold up well. Even in saltwater use the lights have not failed in a year usage.
by: Pete E.09/28/2016
Had a little problem with shipping, tracking showed lights were delivered, however never arrived at my location. Emailed eTrailer with my problem and they shipped replacement units immediately. Fair pricing, quick turnaround, and great people to work with. Quality of marker lights was as advertized. 100% satisfied.
by: Ron L.11/10/2014
As always from etrailer.com, the product exceeded expectations. I had a minor accident with my trailer and needed a new running light on only 1 side of the trailer. When the lights arrived (within a very few days) I installed the new light to replace the broken unit. To my surprise, although the etrailer light looks identical to the original in both size and shape, it is at least 3 times brighter than the identical original equipment (OEM) light that sits on the opposite side of the trailer. So I guess one could easily conclude the etrailer light is about 3 times better than the OEM light. Needless to say, I am very pleased with the LED light, the Customer Service lady who helped me match just the right light to my OEM trailer, the super fast shipping, great prices and a great inventory. I don't know why anyone would go anywhere else to buy their trailer parts. Etrailer.com has it all!
by: David04/08/2013
I wanted to replace the finicky original incadescent lights on my utility trailer. I ordered a pair of these to go with the LED trailer light kit. Once I figured out how to use the ScotchLok wire connectors (included with the trailer kit) it was easy to hook these up. It is great to have four lights all working correctly at the same time.
by: J Perkins09/22/2017
Needed new marker lights for a utility trailer. These are an exact replacement. I connected the white lead (ground/negative) to the mounting stud. LEDs provide good light for visibility and reflectors are bright. I liked them so much that I ordered a second pair for another trailer.
by: Jeff S08/14/2017
Using these as side marker lights on my jetski trailer. The old light used the mounting stud for ground, these lights have a separate ground wire with a ring terminal on it. No problem, just had to drill a hole to screw the ring terminal to the trailer frame. Lights are bright. I took the lens cover off, the LEDs and circuit board are potted to prevent water from corroding them. So these lights should survive dunking in the lake/river/ocean.

- Why Does Ground Wire Corrode on Aluminum TrailerThank you for the photo and what is causing the ground wire is the aluminum trailer; it's called galvanic corrosion and is an unfortunate side effect of having an aluminum trailer. This happening once every 18 months or so sounds about right and the truth is there simply is no fix for this. You'll have to just use a wire brush and remove the white powder - the corrosion - and then re-attach the ground. I know it's an inconvenience but it is the only thing you can do in this case.

- Is the Ground Wire Needed for the Square LED Trailer Clearance and Side Marker Light to WorkYes, the second wire will need to be grounded to complete the circuit for the LED Clearance Light, # MCL36AB. If your trailer connector has a ground wire that is connected to the trailer frame at the front of the trailer, you will be able to just secure the ring terminal on the LED trailer clearance light, # MCL36AB, to the trailer frame with the light mounting bolt or a self tapping screw (not included). If your trailer connector does not have a ground attached to the trailer frame you...
view full answer... - Can Clearance Light with Black and White Wires Replace Light with 2 Green/Brown WiresYes, the replacement light will still work. Although there are common colors for the wiring on a trailer, nothing is set in stone so the colors of the wiring can vary. Just be sure to ground the white wire of the Optronics Square LED Trailer Clearance Light # MCL36AB to a clean, bare-metal surface to avoid shorts on your light circuit.

- Can Trailer Lights Ground to Frame of Trailer As Well as Ground Wire of ConnectorYou can ground your trailer lights to the frame of the trailer or back to the ground circuit that the trailer wiring connector has. The main ground strap from your wiring connector connects to the frame which basically makes anything that touches the frame grounded.
view full answer... - Square LED Trailer Clearance Light Compatibility with a 24 Volt SystemI am sorry, but no, the MCL36AB LED bulb will not work with a 24 volt system. It is a 12.8 volt bulb. As far as the life expectancy, there is a lifetime warranty on the LED bulbs; but please do not attempt to use them with your 24 volt system. They will not work, and may completely compromise the system.
view full answer... - Can I Ground Trailer Lights To Trailer's Main GroundYou can ground all of the trailer lights like part # MCL36AB to the main ground on the trailer. We normally recommend to attach the grounds to a clean bare metal surface of the trailer frame for a better connection. If you have ground issues after connecting the grounds to the main ground, I recommend to ground to the frame.
view full answer... - Recommended Red Square LED Trailer Clearance LightFor your boat trailer, you will just need the Optronics LED Trailer Clearance, SIde Marker Light with Reflector - Red # MCL36RB. This is the exact size and design as the Amber # MCL36AB that you referenced and will mount using the included 5/8 inch stud. This is a very nice, square LED clearance light that measures 2-7/8 inches long, 2-1/8 inches wide and 15/16 inches deep. I have attached a short video demonstration on this product that you can also check out.
view full answer... - Are Mounting Brackets Available for Optronics Mini LED Clearance Lights # MCL95AB and # MCL95RBThe 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...

My 4-year-old Staffordshire Terrier, Koko, has enjoyed chewing up 8 different TV remote controls in the last 2 years. Fortunately we do offer a replacement lens for your Optronics light # MCL36AB. The replacement amber lens is part # A36AB.
view full answer... - Armored LED Clearance Light # 424000 Recommendation for a 2007 Jumping Jack TrailerThe reason some lights have two wires and others only have one wire is because some lights ground through the mounting studs (one wire lights) while other lights have two wires, a power wire and a ground wire. If your old lights were one wire lights and you wanted to use a Square LED Trailer Clearance, part # MCL36AB, you could run the ground wire to the mounting stud for the light and you would be good to go. We do not sell rock guards for the # MCL36AB, but we do sell armored clearance...
view full answer... - Availability of Optronics LED Trailer Clearance Lamp # MCL71RB in AmberThe closest thing we have to the # MCL71RB in amber would be the Optronics # MCL36AB, which is also available in red as part # MCL36RB. The lamps are a bit smaller than the # MCL71RB at 2-7/8 by 2-1/8 inches. Optronics doesn't offer that lamp in amber as an LED version.
view full answer... - How to Install 1-Wire Optronics Trailer Clearance or Side Marker Light w/ ReflectorWhile we don't have a video showing how to install the Optronics Trailer Clearance or Side Marker Light w/ Reflector # MC76AB, I can tell you that the black wire needs to be connected to your trailer running light circuit and then the hardware used to mount it needs to be installed on a clean, bare-metal surface because that is how the light grounds. Similar to the attached install video of the Optronics light # MCL36AB but different in that this light actually has a ground wire.
view full answer... - Amber Trailer Lights Similar to MCL-71RBThe closest thing we have to the # MCL71RB you referenced in amber would be the Optronics # MCL36AB, which is also available in red as part # MCL36RB. The lamps are a bit smaller than the # MCL71RB at 2-7/8 by 2-1/8 inches. Optronics doesn't offer that lamp in amber as an LED version.
view full answer... - How Do I Convert My Incandescent Trailer Lights to LED LightsYes, you just have to remove the old lights, match the wires and mount the new ones. Please note, that it is usually not a good idea to mix LEDs and incandescent lights, so if you have have side markers or other lights on the trailer, make sure you switch those to LEDs as well. Incandescent lights draw much more amperage than LEDs do, and if they pull that current through the LED fixtures, the LEDs could burn up. We have LED side markers and clearance lights like part # MCL36AB and part...
view full answer... - Tracking Down Possible Trailer Ground Problem to Repair Running LightsAs a first step, you will want to determine if the wiring problem is on the tow vehicle or the trailer. You can begin by using a circuit tester like part # PTW2993 to test the trailer connector on the tow vehicle while a helper activates each function. If you get no signal on the pin that feeds the running lamp circuit, you know the problem lies with the tow vehicle. If this is the case, you will need to check fuses or the wiring connections of the trailer connector. Also, check the connector...
view full answer... - How To Wire a Square LED Clearance Light to a Honda CivicThe square LED trailer light, part # MCL36AB, is designed to be used on 12 volt systems, usually as a clearance light for a trailer. As long as the black wire is attached to a 12 volt power source and the white wire is grounded, this light will illuminate. I would recommend you test the wires from your Honda Civic with a Circuit Tester, part # PTW2993, and make sure that the wires you are using have 12 volts when you are wanting this light to illuminate. The next thing you should check...

I linked our main page for horse trailer products and also our specific page for clearance lights. We have both standard incandescent bulb and high-efficiency LED types (that use much less power) in many shapes and lens colors. For a low-cost rectangular incandescent amber clearance light we have # MC48AB from Optronics. This uses mounting screws that are spaced apart 3-3/8-inches...
view full answer... - Which Part Numbers Are the Clearance Lights In the TL5RK Trailer Light KitIt sounds like you're looking for the clearance lights that came in the Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK. Those are available with part # MC36AB (incandescent) or # MCL36AB (LED).
view full answer... - LED Trailer Lights Not WorkingThanks for your recent purchase! This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached...
view full answer... - Not Getting Turn Signal Function When Using LED Bulbs On A TrailerLED bulbs have little resistance on their own, so when used with turn signals they can create a hyper flash situation, which is a fast flashing of the bulb. To determine if you will need a load-resistor kit like a LED Light Bulb Load-Resistor Kit # DI34ZR, you will install the bulbs and when the turn signals are activated, if the bulbs hyper flash you will need to install the load-resistor kit. This kit will prevent the turn signals from hyper flashing. You will need one kit for each LED...
view full answer... - Replacement Trailer Taillights and Wiring for Trailer that Doesn't Need License Plate LightSince you don't want a license plate light or bracket what you'd want is two of the part # STL38RB for both sides of your trailer. For a couple amber LED clearance lights you could then use the part # MCL36AB and for a wiring harness part # A20WB.

- Troubleshooting Trailer Lighting Where Only One Running Light WorksSince all of your trailer lights operate properly with the exception of one of the running lights, this tells us that the vehicle wiring harness is probably working properly. I would first carefully check the bad light's ground and power wires to ensure that both are secured. If the light uses a separate ground wire, usually a white wire like on # MCL36AB, that ground wire needs to be affixed to the trailer frame, to a clean rust-free bare metal surface. If the light is the type that uses...
