Black Molded ABS Mounting Bracket for Thin Line Series Clearance, Side Marker Lights - A65B

Average Customer Rating:  4.8 out of 5 stars   (53 Customer Reviews)

4-1/16" L x 1-1/16" W x 5/8" D; Molded plastic ABS; weather resistant; surface mount on 3" centers; use with MC65 series lights


Replaced 18 year old lights on my trailer with these easy to install mounting brackets. They worked well with the Two Wire Plug (68P) and my new LED side markers(MCL63AB MCL63RB). Even with some minor wire repairs, it took less than 30 Minutes for all four side markers. Instructions were clear and concise (not written by some one in China)!

Best customer service for a Web Site Company I have had.


Here is a picture of these in use on the front of my truck, its an unorthodox mounting place and its supposed to be used on a trailer but I really love these things and I have installed them onto another guys truck as well


Perfect find for my Grand Design 2670 MK


The perfect replacement for 20+ year old stock brackets that have become brittle with age.

Hasnt broken yet.
Gary - 09/12/2021


I placed my order and with in a couple of days received it. Products were packaged well and arrived in good shape.quality product and quality service! I would definitely order additional products if needed.thanks!


Exactly as stated so it matches the old ones on my trailer!


Excellent product. Took me longer to get the screwdriver than it did to replace the broken one. Once in, the light snapped right in. Haven't had any problems since.

Still holding up like the day I installed it.

Order process went very well. Very pleased. Thank you.

Haven't installed these yet , but they are as described.


Perfect replacement for broken base on trailer. Works with both auto bulbs & LED.


Great product


My old brackets got brittle and broke when upgrading to LED. These fit the bill perfectly.


I had broken a fender mount setting equipment on it. I got this to replace it. My only complaint is there isn't a spot to run the wires under that match my fender wires, from the side. This isn't a defect in design or manufacturing so I don't hold it against them. I knew this would be a problem.


I have ordered parts for my truck , my friends cars and trucks . Service is always up front , parts are mad clear , I think i made 1 or 2 phone call and was taken care of right a way you know your stock . Shipping is always no problem with in a few day most the time it it before due date. Great people to deal with . Lots of other company should take your lead in service. Over the years i don't think i had to return anything but i have no doubt it would be the same service .


While etrailer's products have been good so far (I have ordered several items lately), what really pleases is their quick and pleasant service. Always easy to deal with, and that makes a difference.


Worked on our trailer side light


Quick delivery and correct parts, once again etrailer exceeds expectations.


Great product


Works as advertised, used with LED side marker


Always have my trailer needs and at reasonable prices and the fastest shipment!


Absolutely needed with certain other assemblies. Very well made and easy to install.


Fastest order completion and shipping . Will always use them.


Every thing is just as it should be. Thank you for your quick order and fast delivery.
You guys are the best.

All is well. Product and service have been great thanks for your inquiry.
Jeffrey - 12/17/2018


prefect match for my 14 year old trailer, thanks


The parts fit well and are working just fine. Happy to do business with you again as soon as I need something. Thanks

  • Replacement Mounting Plate for Kaper II Side Marker Lamp 1A-V-1260AR
    I may have a solution for you, but the 1a-v-1260ar part number you've mentioned corresponds to a Kaper II marker lamp, which is a brand that we do not carry. However, it looks like the Optronics Thinline LED Trailer Fender Light for Trailers Over 80" Wide - 10 Diodes - Amber/Red # MCL65ARB is a similar light and the back mounting plate for that MC65 series light is the Black Molded ABS Mounting Bracket for Thin Line Series Clearance, Side Marker Lights # A65B. I've linked a photo of the...

  • Fender Bracket for Optronics Thinline LED Trailer Light # MCL65ARB
    For the black molded fender bracket that works with the Optronics Thinline LED Trailer Light # MCL65ARB you will need the part # A67BB, which is indeed sold separately. This bracket includes the lead wire for power. If you are just needing the standard surface-mount bracket you can use part # A65B for just the bracket itself or # A65PB for the bracket and wire.

  • Mounting Bracket Options for Optronics Sealed, Thin Line Clearance Side Marker Light # MC65AB
    There are five mounting brackets available that fit the Optronics Trailer Clearance Side Marker Light # MC65AB. These three are all black plastic. They are Optronics # A65PBPG, # A65PB and # A65B. The first two come with a single wire, the differentiating factor is the # A65PBPG comes with a plug-n-go male connector whereas the # A65PB is intended to be hardwired. The third one, # A65B is the bracket without the wires. If you would rather have a chrome colored plastic bracket, Optronics...

  • Which Mounting Bracket for Optronics MCL61ARB Light
    I have a solution for you, but the # MCL61ARB does not fit in the # A67BB bracket. The # MCL61ARB light that you're using requires the # A65B bracket for mounting. You may also need the Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights # A65P since this light grounds through the mounting hardware (if you have a single wire light).

  • Mounting Base and Wiring Harness for Optronics Clearance Light # MCL63CAB
    There are different bases you can use for clearance light # MCL63CAB. You can use base # A65B that you have referenced. For that particular base you would use wiring harness # A68P. We also have base # A65PB or # A66PB. With these you would use wiring harness # A65P with the single wire because the light will ground through the mounting studs of these bases.

  • Height of the Thin Line LED Trailer Clearance Light # MCL75RB When Installed in Mounting Bracket
    The Thin Line LED Trailer Clearance Light # MCL75RB is 7/8 inch deep and the install bracket part # A65B would add 1/4 inch of depth to the overall height of the light setup. That means that overall it would 1-1/8 inches tall.

  • Available Plastic Mounting Brackets for GloLight Thinline Clearance Lights
    The Black Molded ABS Mounting Bracket for Thinline Series Clearance Lights, # A65B, are compatible with the Optronics GloLight Thinline Lenses, # MCL165RB. The mounting brackets will allow you to mount on standard 3 inch centers and the overall dimensions are 4-1/16" L X 1-1/16" W X 5/8" D.

  • Chrome, Two-Wire Mounting Bracket for the Optronics Clearance Light MCL63CAB
    Sounds like you are wanting to use the part # A67CB with the clearance light part # MCL63CAB. There's no reason you couldn't, this bracket is designed for trailers that ground through the mounting hardware though. If that wouldn't work on your trailer you would just need to run a wire from the mounting screw that runs through the ground strap and the light would work just fine.

  • How is Sealed, Miro-Flex, Thin Line, LED Trailer Marker/Clearance/ID Light, # 12855, Wired
    Sealed, Miro-Flex, Thin Line, LED Trailer Marker/Clearance/ID Light, # 12855, requires a bracket to mount the light. The light itself can plug into the bracket and ground through the mounting hardware. One possible bracket is the Chrome Bracket and Single Wire Plug for Thin Line Trailer Clearance and Side Marker Lights, # A67CB. If you are unable to ground the light through mounting hardware, you can use Two Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights, # A68P....

  • Mounting Bracket Recommend for Running Power and Ground Individually to Thin Line Clearance Lights
    To use the # MCL63RB and run the ground and power wires directly to it you would need the part # A68P as well. This would allow you to wire up the light without having to ground the light through the mounting hardware. For a bracket you would then want the part # A65B.

  • Replacement Side Marker Light for 2015 Dynamax Dynaquest RV
    In order to find a replacement side marker light for your 2015 Dynamax Dynaquest I recommend taking some measurements of the current light. There is not a direct replacement available so you will need to find something that is a close match and ideally uses the same mounting hole dimensions. The Miro-Flex Thinline LED Trailer Clearance or Side Marker Light # MCL63AB you looked at uses the same 2 prong plug you have now and measures 4-1/16" long x 1-1/4" tall x 1-1/8" thick. The distance...

  • Recommended Trailer LED Taillights for a 1961 Airstream Camper
    The fact that your trailer uses single wire assemblies for the running lights indicates that the assemblies are intended to ground through the mounting hardware. Which is interesting since the trailer is aluminum. For red surface mounted LED clearance lights the part # MCL63CRB that you referenced would work well, for the amber version part # MCL63CAB. For an install plug you would want part # A68P and then for a bracket part # A65B. Or for an entire kit that comes with everything you...
