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
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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL-91AK Review
Today we're going to be taking a look at part number MCL-91AK. This is the Optronics Mini Thin Line Sealed LED Side Marker or Clearance Light. It's an amber light. It's going to come with the LED light, the chrome all-weather mounting bracket, you're going to get your wire plug, and your mounting hardware. This is designed to function as a clearance or side marker light. Here at the light, it's going to feature a nice amber lens. It's going to be sonically sealed, waterproof construction.
The mounting bracket's going to have a nice gasket here on the back side for a nice, tight seal when you're ready to install. It is designed to ground through the mounting hardware. It's a surface mount installation. If we take a measurement, the distance that we have between our mount holes, measuring center on center, that's going to be right on 2". The actual light is going to give us an overall length of about 2 1/2", an overall depth of 1 3/16", and then a thickness of 7/8". It's really easy to get it installed onto the bracket.
All you got to do is place it in there, push it until you hear it snap into place. Now with it installed in the bracket, our overall length is now 2 7/8", overall width is now about 1 1/2", and then the thickness, or the depth, is going to be 1 1/4". This light is going to draw 0.051 amps at 12.8 volts. Again, mounting hardware is included, as well as the plug. It's got the open back design here, so you can easily get the plug install into the slot where it needs to go. Now those ports are going to come pre-lubed with some dielectric grease, that way it's going to protect the connection points from any type of rust or corrosion. We're going to go and hook this up to our external power source, that way you can see what it looks like with power running to it.
We'll also be able to turn off our overhead lights so you can see the light in a low-light setting. Here you can see it's going to contain three diodes. Again, it's an amber side marker or clearance light. Sends out a nice, consistent signal. LEDs are going to be great replacements for incandescent lights. They're much more efficient, they burn brighter, they last longer, and it's going to optimize your light output with the multi-diode design. The last thing I want to show you is how easy it is to remove the light from the housing if you ever need to do so.
I find it easiest to do with a flat-head screwdriver. I'm going to put a little bit of pressure with one finger here on the back of the light. Place the flat-head in there and just tilt it for a little bit of leverage. It's going to allow the light to come right out. That's going to do it for today's review of part number MCL-91AK. This is the Mini Thin Line Sealed LED Side Marker or Clearance Light from Optronics. .

The lights are excellent, a direct replacement. i ordered lights with the chrome frames but not really thinking I would actually use the frames, however trying to get the old lights out required either breaking them or the old plastic frames. Only 4 stars because the new frames require drilling new holes. I went through many websites and even yours I wasn't completely sure I was getting the right lights until they arrived. 317274

Good quality lights, just be sure to drill the hole for the power wire over size so that the power port on the back of the light doesn't ground out on the trailer frame. 544994

Bought a brand new trailer and from the get go some of the regular lights were intermittent. Finally had enough and ordered LED's to replace them all; have not had a single light issue over a year later. All were direct drop in replacements, fit and look great. Thanks etrailer.com! 461013

Ask the Experts about this Optronics Trailer Lights
- How Does Mini Thin Line Sealed LED Trailer Marker/Clearance Light, # MCL-91AK, InstallThe Mini Thin Line Sealed LED Marker/Clearance Light, # MCL-91AK, will attach to the trailer using 2 screws which are included. I have included a picture showing the mounting holes for you.

- Solution for Routing Power Wire of Trailer Clearance Light to Prevent Wire Damage/ShortYou might consider drilling out the hole for the power wire of the part # MCL-91AK to fit through if the clearance is as tight as you described. That would be the best way to have enough clearance to prevent damage to the wire which could potentially cause a short.
view full answer... - Difference Between Optronics Mini Thin Line Sealed LED Lights # AL82AB and # MCL-91AKThe Optronics Mini Thin Line Sealed LED Lights # AL82AB and # MCL-91AK differ in that one (# MCL-91AK) includes a chrome-finish base, single wire hookup and grounds through the mounting hardware while the other uses two wires for hookup, 12V and ground, and includes a gasket for installation. A pigtail plug like # A46P135B is not needed for either of these.
view full answer... - Grounding the Optronics Thin Line Sealed LED Marker/Clearance Light # MCL-91AKYou are correct that the Optronics Thin Line Sealed LED Marker/Clearance Light # MCL-91AK that you referenced will require a jumper ground wire to be run to a metal portion of your trailer frame if it is installed on a plastic surface. You will want to use a ring terminal like # DW05740-1 to make a solid ground connection to the trailer frame. Sanding off any paint from the grounding spot will help ensure a good connection.
view full answer... - Availability of a Red Mini Thin Line Sealed LED Marker/Clearance LightFor a red Mini Thin Line Sealed LED Marker/Clearance Light, you will need to use # MCL-91RK. The R in the part number indicates that it is a red light.
view full answer... - Availability of Red and Amber Optronics ThinLine Mini LED Side Marker or Clearance LightsThe red lens equivalent of the amber Optronics Side Marker Light # MCL-91AK that you referenced is part # MCL-91RK. I've attached review videos for both that you can check out.
view full answer... - Ordering Aero Pro LED Trailer Light Kit with 4 Clearance LightsThe LED trailer wiring kits we offer like the part # TLL36RK do only have one set of clearance lights that come with them but you can easily add additional ones with like the # MCL-91AK and you'd have all 4 that you'd need. So you'd want to order the # TLL36RK and two of the part # MCL-91AK and you'd be set.
view full answer... - LED Trailer Light Recommendations for a Trailer Over 80 Inches in WidthI attached a help article that details all of the various taillight requirements for trailers based on their dimensions. A good kit to start with would be the part # TLL36RK, for an ID bar part # MCL84RB and then for red ID lights for the rear part of the side of the trailer part # MCL-91AK.

- How to Tow a Trailer with Reverse Lights 2013 Nissan LeafYes, the Submersible, Over 80" Aero Pro LED Trailer Light Kit part # TLL36RK, Light Guide LED Backup Light part # BUL602CB, 25 ft. Wishbone 5-Way Trailer Harness part # A25W5B, and Right Angle 3-Wire Pigtail for Optronics Trailer Lights part # A47PB will all work together and give your trailer reverse lights.

view full answer... - Does Optronics Red Side Marker Light Include a Base and WiringTrailer light # MCL-91RK includes the red clearance light and chrome housing in addition to the plug. Basically it is exactly like # MCL-91AK except it is red instead of amber so they will match.
view full answer... - LED Lights for 1991 Ranger Boat TrailerWe can get you all the lights you need though it will come in the form of different parts because there isn't a specific "kit" containing everything. For the stop/turn/tail lights you can use the GloLight LED Trailer Tail Light # STL178RFPB; this is a surface mounted light that is 7-1/2" wide x 3-5/16" tall x 1-1/8" deep and has an industry-standard 3-prong plug to connect to your trailer. Then for your clearance lights you can use # MCL-91AK, which is amber and measures 2-1/2" x 1-3/16"...
