Optronics MCL36 Series LED Marker Clearance Light Dimensions

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 like these little lights. I used them as rear marker lights across the back of my trailer. Wiring them up was simple. I just grounded the white wire to the light's mounting stud. Installing them would have been simple if I didn't have to drill through such thick U-channel, but I can hardly blame that on the lights. A year after install, they're still working great.



by:

A bright idea.



by:

Well I ordered these lights and they were delivered within a week, I am very impressed with them, easy to hook up, and very bright. I would recommend this product to anyone who needs or wants a good pair of clearance lights.



by:

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!



by:

Excellent delivery time and great price makes for a very satisfied coustomer every time! Perfect replacement for my old side marker lights, only now I won't have to worry about it burning out or rough roads jostling the filament. Exact fit and easy to install. Five minutes per light and done! Bookmark these guys for ALL of your trailer parts.

Perfect lights, bright and dont have to worry about them being dunked under water when launching my boat!



by:

I installed these lights when rewiring my trailer about a year ago , haven't had any problems .

Trailer gets used twice a month



by:

Its been a year and these led lights are the best. Can be seen during sunshine, rain and lit up like a Christmas tree at night. Thank you etrailer for these high quality lights.



by:

I only installed 1 of the 2 I purchased. But when I did, I spent the night basking in the red glow that it put off. So much brighter than the old bulb style it replaced. Have had no problems with it. Would buy again.

1 year later and I still love it! The LEDs are way better than the old bulb lights they replaced even being a year old.



by:

Was tired of standard incandescent type marker lights having bulbs shift or burn out and not work. I have a Doolittle trailer and the LEDs are good replacement alternatives at a good price. I bought multiples of amber and red, and barring any difficulty, they should be an even swap out.

E-trailer shipped in a timely manner, pkg. was good, and they provided tracking with UPS. Will definitely use them again for trailer lighting, and would highly recommend this product.



by:

Stripping down a 16 year old 21 ft. salt water use trailer - from end to end. The folks @ etrailer were very knowledgeable, and helpful in my decision making. From placing the order, to tracking the order, to the way the items were packed for transit. Other distributors could learn from these people; in regards to customer service, following up, both office and warehouse. Unloaded the products last night, nothing short, all quality in regards to their products, with great pricing. The installation videos are a big bonus, and something I'll be taking advantage of, during the restoration. Will follow up with picture, (before and after) when I'm done



by:

I'm switching over to LED because my brother has good luck with them, and also because the DOT is cracking down on trailers in my state. Commerical guys are getting pounded with insanely high tickets for even one light out. These LED's have 6 per lamp, so if one fails, I'm told, you are still good. I don't have commericial trailers, but I am suspicious of governments that can't manage their money and look for was to screw over residents. I decided to gradually migrate to these lights on all my trailers.



by:

The LED light is sealed so moisture will not be a problem. Much brighter too.

Michael

The LED lights are a great improvement. So much brighter with no moisture in the light.



by:

Reworking my Pacwest Trailer and these are the original equipment replacement, only new LED. Much brighter, less draw and look sharp. Even bought a couple of extras.



by:

Used these to replace factory lights on trailer. Very nice and better than what I had

Still going and no problems after 1 year



by:

I really like these lights. I used them as marker lights on the back of my boat trailer. They were easy to install and after more than a year they are still working great.



by:

I love you trailer marker lights. They were exactly what I needed . And they look really good too ! Nice and bright. I am going to order more light next week. Amber and Red. Thank you etrailer.



by:

Nice product for the buck. The lenses reflect well for my application (equipment trailer) and what I like are the bright 6 LEDs.



by:

Good, Heavy duty product. Great service and shipping from etrailer.com!

Will purchase from them again!



by:

excellent service



by:

Product seems very good. Wire leads are short but most are. Easy install but a lock-washer or locking nut would be very helpful. Without them light will eventually become loose.



by:

still working after 10000 miles and lot of vibration.



by:

Worked very well, nice and bright, just make sure the ground wire is attached to clean bare metal.



by:

Nice lights for the money, easy mounting and are bright. got 2 amber and 2 red for the sides of the trailer.



by:

The videos demonstrating the product and installation are extremely helpful and your service is great. This is my second purchase from you and will not be my last. Thanks



by:

Very fast shipping arrived within a few days. Love the looks of these newer clearance lights.

  • Do I Need to Do Anything Special to Convert 1979 Skylark Camper to LED Exterior Lights
    There won't be any conversion needed to go from incandescent lights to LED lights on your camper. You'll simply connect the power wires and connect the light's ground wire and you'll be good to go; you could use something like the Optronics LED Trailer Clearance or Side Marker Light w/ Reflector - 6 Diodes - Square - Red Lens # MCL36RB to replace your old red clearance lights. As long as you're replacing all of the lights on your camper with LED lights you shouldn't experience any issues...

  • Will Non-Submersible Clearance Lights Work on a Boat Trailer?
    The Square LED Trailer Clearance Light, # MCL36RB, is non-submersible, so if it gets submerged in water, the possible damage includes short circuits, cracked lenses and burned out bulbs. This light is not sealed, and does not have a drain hole which lets water out if it does get in, like some submersible lights do.

  • Not Getting Turn Signal Function When Using LED Bulbs On A Trailer
    LED 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...

  • 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...

  • Recommended Red Square LED Trailer Clearance Light
    For 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.

  • Availability of Optronics LED Trailer Clearance Lamp # MCL71RB in Amber
    The 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.

  • How Do I Convert My Incandescent Trailer Lights to LED Lights
    Yes, 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...
