Optronics Thinline MCL65 Series LED Fender 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.

Video Transcript for Optronics LED Fendermount Trailer Clearance Light Installation

Today on our trailer we're going to install the Optronics LED fendermount, trailer clearance, marker light with bracket and wire. This is a red/amber light, part number MCL67ARB. This light will function as both the clearance and marker light. Here we have our light. We have the light assembly and the base. The pigtail has the bullet-style connector. However, we're going to be going into a heat-shrink butt connector, so I'm just going to cut that bullet-style connector off and strip it back.

I'll then go ahead and feed it through the pre-drilled hole. As I feed it through the pre-drilled hole, it will also allow the two attachment points to line up with the pre-drilled holes in the fender. Here on the front side you'll notice that there is a metal strap that will connect to the pigtail. That's our ground. I'll go ahead and feed the wire down and line up the holes. Then go ahead and use a couple of self-tapping screws to secure it. Here, underneath the fender, is our pigtail that we've already stripped back.

On the other side that we'll be connecting to is our power wire with a pre-installed butt connector. We'll go ahead and take the pigtail, feed it into our butt connector and crimp it down. Once we have it crimped down, we'll need to heat up the heat shrink around the butt connector. Now, ideally, you'd use a heat gun, but if you don't have one available, a super-hot hairdryer, small torch or even a lighter will work. Just be careful not to melt the insulation of the wire. Just like that, we've gone ahead and secured our base and made our electrical connection.

We'll now go ahead and install the light. The two prongs from our light will line up with the two sockets on the base and snap into place. Just like that, we've completed our install operation and checking of the Optronics LED fendermount, trailer clearance marker light, part number MCL67ARB. .

Great Products at a great price. My local store wanted to charge me more than twice the price I was able to purchase from you.I will purchase from your company within the next two months. I have additional lighting requirements for my trailer.

we had a tire blow out on our horse trailer that caused the original fender clearance light to pop off. luckily the base was ok and fender damage was minimal. finding an LED replacement locally was not an option. I ordered 2 of these snapped one on and it lit right up no problem. Now we have a spare just in case! Thank you etrailer for having the right parts at a great price 256585

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. 406142

We do our best to package our orders so that they will arrive to you in good condition. I will send this to our shipping department manager for review.

I can see the amber part of the light very well shining in my rear-views in daylight; don't yet know if this will be a distraction at night. Very visible compared to non LED. This light is made to accommodate a good sized bracket mounting screw under it; if you use a pan head screw you shouldn't have to worry about interference-check first. 238415

This light is the real deal. Get yourself a pair.

I cant tell you how disappointed I am...........that I did not find out about etrailer.com until now. The LED marker lights that I installed on my Haulmark Lowhauler are simply amazing. They are brighter than the big name companies truck lites out there that I had bought. It is too late for me to return my other lites but I went ahead and changed all the lights on my Nautique boat trailer with your products. It is the difference between night and day. Thanks for the great products. You have gained a NEW LOYAL customer. Speaking of that... I placed another order today. Thanks again!! 73756

Very disappointing that the LED's began failing after one season. However, I like that the entire light can be replaced by a plugin replacement. I am replacing the burned out lights with new ones. There is no comparison between these and incadescents. They are many times brighter and as the diodes die, one by one, you have the opportunity to get new lights before all the diodes in the light fail so you are not left completely without. 200486

My truck is grey, my trailer is grey, I replaced all the marker and tail lights on my 09' 7x14 tandem HaulMark with these and now have better visibility during the day. After a year i still am very happy. I noticed the lights are directional, so if your at the side during the day you have to look at them straight on to see if they are working but thats really not an issue. You have markers on all four sides just for that reason as well as reflectors. I have actually gotten unsolicited compliments from other contractors on the trailer since i got these. 272924

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. 109588

Product was an exact replacement for a damaged light and it was simply plug and play. The only comment I have is that I missed the fact that this item was only the light and did not included the wired mounting base. I noted that you carry the mount as a separate item but I don't recall a note in this item description that the mount, if needed, was not included and had to be purchased separately. My apologies if I missed that. Perhaps a cross-reference in your catalog to the mounting base would be helpful. Fortunately, my mounting base was okay and the new light plugged in and worked. 654669

As mentioned in the product description, the mounting brackets are sold separately, as the correct bracket will depend on where and how the lamp is mounted. The available brackets are shown in the related product section above.

  • LED Replacements for Trailer Clearance Light Part 154A-R and PM-102
  • The closest LED replacement we have for the Trailer Clearance Light part 154A-R is the Thin Line LED Fender Clearance Light part # MCL65ARB. This light has both a red/amber lens, 10 diodes, and measures 3-15/16" long x 1-1/4" wide x 7/8" tall. For a direct fit bracket/harness you will need to use the Black Bracket and Single Wire Plug part # A65PB. The closest LED replacement we have for the Trailer Clearance Light part PM-102 is the Round Marker / Clearance Light part # MCL0039ABB....

  • Recommended LED Trailer Lighting For Over 80 Inch Wide EZ Loader Boat Trailer
  • For your trailer wiring, I recommend the Submersible, Over 80" Aero Pro LED Trailer Light Kit w 25' Wiring Harness # TLL36RK along with the Identification Light Kit for Trailers over 80" Wide - Submersible - 3 LEDs - Red # MCL22RK3B. I recommend the Sealed, Thin Line LED Fender Clearance Light for Trailers Over 80" Wide, 10 Diode - Amber / Red # MCL65ARB for your fender lights.

  • Fender Clearance Light Replacement for 2010 Cimarron Horse Trailer Norstar VP 3H GN
  • Yes, the light part # MCL65ARB is the correct replacement for what you sent in a picture of on your horse trailer. The mounting bracket in the picture is the same as the part # A65PB so it's a match.

  • Fender Light Bracket Recommendation for Cargo Mate Box Trailer
  • For the Black Molded Fender Bracket # A67BB that you referenced the correct light assemblies have both an amber and a red light on them since one side will be for the front (amber) and the other side of the light will face the rear (red). The two options are part number # MC65ARB for an incandescent bulb and # MCL65ARB for an LED. This setup can be made to fit nearly all fenders so it would work well for you.

  • Wiring a 2011 Victory Motorcycle and Trailer for Towing
  • For simplicity, I would recommend wiring the motorcycle trailer as a vehicle trailer would be. A powered converter wiring kit, like part # 119179KIT, would be connected to the motorcycle, which would provide a 4-pole trailer connector. The converter combines the brake lamp and the directional signal onto one circuit. The 4-pole connector utilizes four circuits, the white wire which is the ground, the green wire carries the right turn and brake light combined on one circuit, the yellow...

  • Does Optronics Black Molded Fender Bracket # A67BB Come with 1 or 2 Brackets

  • Recommended LED Clearance Light that is Red and Amber
  • The Optronics LED clearance light that is similar to # MC65RB, but will be amber and red, is the Optronics LED clearance light # MCL65ARB. This light is sealed, waterproof and is a surface mount. The dimensions are 3-15/16 inch length by 1-1/4 inch width by 7/8 inch deep. You will need a bracket and plug like # A65PB to complete the installation of the Optronics LED trailer light # MCL65ARB. Another option you may like is the LED clearance/marker light with a bracket and wire # MCL67ARB....

  • Is Mounting Hardware Included with Optronics Trailer Light Mounting Bracket # A67BB
  • The mounting hardware is not included with mounting bracket # A67BB. I recommend using screws because with rivets, if you have to remove the bracket for some reason, you may need to drill out the rivets. Screws are much easier to work with. Using steel for a good ground is recommended.

  • Is Optronics Sealed, Thin Line LED Light # MCL65ARB Interchangeable Without Wiring Changes
  • The Optronics Sealed, Thin Line LED Light # MCL65ARB with a sonically-sealed, waterproof lens in a single-unit housing can be used for both the right or left fender without changing the wires. However, to use the LED trailer light # MCL65ARB, you will need the Optronics Black Bracket and Single Wire Plug # A65PB. The kit combines a black molded ABS, surface mount bracket and a molded plastic, single-wire plug and its single-wire design grounds through mounting hardware. This item will...

  • Are Optronics Fender Clearance Lights MCL65ARB and MC65ARB the Same Size
  • Yes, the two Optronics lights you referenced, # MCL65ARB and # MC65ARB, are LED and standard incandescent versions of the same Thin Line fender clearance light. Both install with 3-inch mounting hole spacing and both measure 3-15/16 L x 1-1/4 W x 7/8 D. LED lights offer the advantages of needing less power, not requiring routine bulb replacement and generating less waste heat. They also do not tend to change color (becoming yellow over time) the way incandescent bulbs do.

  • Is Bargman 40-40-104 Fender Mount Red/Amber Clearance Light Submersible
  • The Bargman Fender Clearance/Side Incandescent Marker Light # 40-40-104 is not rated as a submersible light. But we do have combination red/amber lights that are submersible and you can see all of these on the linked page. These include fender-mount lights like # MCL65ARB and both incandescent and high-efficiency LED versions. You might care to refer to the linked article on trailer lighting requirements.

  • How To Attach the Black Molded Fender Bracket A67BB
  • In order to attach the Black Molded Fender Bracket part # A67BB I recommend using the Self-Tapping Phillips Head Screw part # 1131832 because the head will sit closer to the base and will allow for the Optronics Thinline LED Trailer Fender Light part # MCL65ARB to sit flush. The Black Molded Fender Bracket we offer grounds via the mounting hardware so a ground wire is not present but if you have a version of this bracket that does have a ground wire then you can just snip this and tape...
