Video Transcript for Optronics Trailer Lights A65PB Review

Today we're going to be taking a look at part number A65PB. This is the Optronics Black Bracket and Single Wire Plug for the Thin Line Series Trailer Clearance and Side Marker Lights. Again, it's going to be black in color. It's an all-weather, molded, ABS plastic bracket and wiring plug. It is going to offer a surface mount design for MC65 series lights. You'll see that we have the two mount holes right here. If we take a measurement of those and the separation we have, measuring center on center, is going to be 3", which is industry standard.

The mounting hole diameter is going to measure about 3/16". The overall dimensions of the bracket, starting with the overall length, that's going to give us about 4 1/16" in length. Measuring the width, that's going to give us a measurement of 1 1/16" and then the depth is going to give us a measurement of about 1/2". You can see here that it does offer the single wire design. That's going to be for our power. That's going to be a 6" wire lead.

Then this portion right here is going to be our ground connection. This is designed to ground through the mounting hardware. Mounting hardware is sold separately. This part's also available in chrome with part number A67CB and in gray with part number A66PB. Today I'm going to be installing part number MCL65CRB. This is a Thin Line Optronics light.

It's got the two male ports here on the back. Plug directly into the female ports on the bracket. All you have to do is line those holes up and then the light simply just snaps in. It's got clips around the side that secure to the light. It's going to hold it firmly and securely in place. That's going to do it for our review of part number A65PB.

This is the Black Bracket and Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights from Optronics. .

Black Bracket and Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights - A65PB

Average Customer Rating:  4.8 out of 5 stars   (215 Customer Reviews)

Quality product! The LEDs light up brightly. They're brighter than i expected! I bought enough to change out all my trailer lights, it worked out well. So far they've been through some extreme weather. I've used the trailer in heavy rain, high heat, through winter and freezing temps, and many washes. They haven't leaked and lenses still look great. It's only been a year and I'm hoping these will last many many more. 638100

I reviewed this order earlier indicating that the light I received was not the same as the one I ordered from. However, after several emails back & forth with Mr. Breedlove at Etrailer, he was able to provide an explanation for the difference. The manufacturer upgraded the light to a LED which required a different lens than I had on the trailer. I have to admit the LED light is much brighter than the incandescent one on the trailer. I'm impressed with the dedication & perseverance demonstrated to me to help resolve the problem. For that they earned my trust and my business. 71671

Ask the Experts about this Optronics Accessories and Parts

  • What Fastener to Use for Installing Optronics Thin Line Series Light Mounting Bracket # A65PB
    It is not necessary to use rivets for installation of the Optronics Thin Line Series Light Mounting Bracket # A65PB, or the chrome version # A67CB. You can use stainless steel sheet metal screws like # 1172904 or pretty much any hardware that suits your installation location. Both brackets use mounting holes on 3-inch centers and the holes are 1/4-inch in diameter.

  • Protecting Trailer Electrical Connections from Salt Water on a Boat Trailer
    What I recommend doing is wrapping electrical connections using heat shrink tubing # DW05452. This will keep on the water and preserve the metal connectors from the light. I also recommend using dielectric grease # LT37534 between electrical connections to repel moisture. I also recommend running a jumper ground from the light ground location somewhere further up on the trailer (at a spot that won't be under water) so that the ground is not affected. If at all possible, rinse the...

  • Troubleshooting Installation of Side Marker Lights on a 2003 Silver Star Horse Trailer
    I have a solution for you but we do not have an exact replacement for the PM154 that you referenced. I saw that you purchased # MC65RB and the proper base bracket for these lights is # A65PB if you would like black or # A67CB if you wanted a chrome base.

  • What Type of Connector Does Black Bracket and Single Wire Plug # A65PB Plug In To
    The plug that is on the Black Bracket and Single Wire Plug # A65PB is designed for trailers that already have the type of plug-in wiring on the trailer (Plug-n-Go). The wiring that plugs into this end is not available but an auto parts store or store like Radioshack would probably have the matching connector that you could attach to the existing wiring on the trailer allowing you to plug in the lights.

  • What Screws Fit Black Bracket and Single Wire Plug for Thin Line Series Trailer Lights # A65PB
    The back of the lights that go with the Black Bracket and Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights, # A65PB, have a recessed area over the mounting holes. Take a look at # MC65RB, and click on the third picture to see the recessed area. I went out to the warehouse and pulled both parts to measure. There is a space of 3/16 inches between the bottom of that recessed area and the base of the bracket. The screw head would have to be 3/16 inches tall...

  • Trailer Clearance Light Recommendation for a 2009 Haulmark 24 foot Enclosed Car Trailer
    We don't have specific fit information for the clearance lights of trailer manufacturers. We do carry virtually every trailer clearance light though, so the best recommendation I can make is to check out the link I attached to the right that has all of the amber trailer clearance lights we offer. You should be able to find one that would be an exact replacement for your trailer.

  • Lights for a 7 Foot x 10 Foot Cargo Trailer
    It is imperative you check your local laws for lighting requirements in regards to your specific trailer, though I can tell you you no matter what you'll need stop lights, tail lights, turn signals and reflectors. There are other factors, including your trailer's GVWR that you need to take into consideration; I have added a link to a help article on trailer lighting requirements which I highly recommend checking out. That said, a 7' wide x 10' long cargo trailer is almost certain to...

  • 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.

  • What Brackets Are Used To Mount The Sealed, Thin Line LED Trailer Clearance Light Part # MCL75RB

  • Installing Optronics LED Trailer Marker # MCL63AB on Trailer
    In order to install the Optronics Sealed Micro-Flex Thin Line LED Trailer Marker # MCL63AB on your trailer, you will need to add a bracket and wire harness, such as the Black Bracket with Single Wire # A65PB or the Gray Bracket and Single Wire Plug # A66PB. The choice between the two brackets is simply based on color preference, as they will wire and install the same way. The bracket will ground through its hardware, so it just needs a single wire to power the light. You will want to...

  • 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.

  • Recommended Clearance Lights for Pace America Trailer
    I recommend going with the Thin Line LED Trailer Light, # MCL65AB for amber lights and # MCL65RB for red lights. These sealed, dual-bulb lights can be used as a clearance or side marker lights. I have included a link to a video review and installation video of these lights for you. To mount the light, you will also need a bracket like # A65PB for black or # A67CB for chrome.

  • Can I Use Optronics LED Light # MCL75RB in the Same Base as Light # MC65RB
    Yes, both the Optronics lights # MC65RB and MCL75RB use the same mounting base, so the # MCL75RB lights will snap into your old bases. You will then need to wire in the lights, with a power and ground connection. Part # MCL75RB is a sealed LED light light and will burn brighter but draw less power than part # MC65RB. Both lights use either base # A65PB or # A67CB. See the video that I shot showing both lights.

  • LED Version of the Bargman 99 Incandescent Clearance Light # 3499001
    The closest thing we offer to Bargman 99 Incandescent Clearance Light # 3499001 that you referenced that is an LED would be the Optronics Trailer Lights # MCL63RB. Dimensionally these lights are virtually identical. I attached a review video for this light. For an install bracket you would want the part # A65PB.

  • 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...

  • Replacement LED Clearance Lights for 2000 Sundowner Trailer
    The Sealed, Thin Line LED Trailer Clearance, Side Marker Light, 4 Diode - Red # MCL75RB will mount to your 2000 Sundowner as long as the base it connects to is 4-1/16" L x 1-1/16" W x 1/2" D. If you need to replace that bracket, I recommend the Black Bracket and Single Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights # A65PB or chrome # A67CB. We don't have a spec sheet of each trailer, but you can definitely make these work and the dimensions should help you...

  • Replacement Trailer Clearance Light for a Kll 1A-V-1260AB
    I looked up the trailer light you listed and the exact replacement that we carry would be the part # MC65ARB. This light uses the part # A65PB as a mount so the part # MCL61ARB should work as a replacement for you as well.

  • 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.

  • Replacement for Haulmark # 900200 Fender Marker Light on 10 x 5 Enclosed Trailer
    Although I don't have any reference information that would tell me the part or crossover number for a lamp on your Haulmark trailer, I found online that the # MC65ARB you referenced would be an identical replacement. To be sure, take a quick measurement of the existing lamp on the other side. If it measures 3-15/16 inches long by 1-1/4 inches wide by 7/8 of an inch tall when laid on the base, you're good to go. You might consider getting the # A65PB, # A67CB or the # A67BB base, they're...

    The lights that you have referenced, # STL70RB, do have the same measurements as the Kaper lights you have with the exception that they do not stick out as far from the trailer. As for the clearance lights I do not have one that is an exact match for the dimensions you have given. A close match is # MCL65AB. It measures 3-15/16 inches long and 1-1/4 inches wide. To mount it you would need a bracket like # A65PB or # A67CB.

  • Replacing Existing Marker Lights on 2012 Haulmark Race Trailer with LEDs
    You can certainly replace your existing incandescent marker/clearance lamps with LED models. LEDs have many advantages over incandescent lamps. They have a much longer life, they draw a fraction of the amperage and are brighter. The Optronics LED Clearance and Side Marker Light you mentioned, part # MCL75AB uses a chrome # A67CB or black # A65PB mounting bracket. The lamp is fully waterproof. If you are looking for something that is a close replacement for your existing lights, I...

  • Comparing Black Bracket and Single Wire Plug A65PB and Plug n Go Bracket A65PBPG
    For the Black Bracket and Single Wire Plug, # A65PB, the plug on the end of the one wire is different than that on # A65PBPG. The plug n go style on # A65PBPG is easier to attach to the MC65 series of lights, like # MC65RB, because the cable is molded around the connector. This also covers any exposed wires that would normally be present like on # A65PB.

  • 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....

  • Replacing Optronics Thin Line Incandescent Trailer Light with Thin Line LED Trailer Light
    You are exactly right. Changing out your # MC65RB incandescent lights for new # MCL75RB lights will simply require removing the existing light and snapping a new light into the same housing. Both of these lights use the # A65PB bracket. If any of the brackets on your trailer need replaced you can use the # A65PB as a replacement, but the LED lights will not require any different base than the incandescent lights. I have attached an installation video of the # MCL75RB light for you.

  • How To Mount Optronics Trailer Clearance Light # MC65ARB To Trailer
    To mount the Optronics Trailer Clearance Light, part # MC65ARB, you will need to use a mounting bracket. There are 2 brackets available that will fit this light, the only difference between brackets is the color, one is black, one is chrome. For the black mounting bracket, Optronics Bracket, part # A65PB. If you prefer chrome, we have the Optronics Bracket, part # A67CB. You will need to supply screws to mount the light brackets.

  • How Does the Optronics Light # MCL75RB Install on a Two Wire Lighting System
    When installing the Optronics Sealed, Thin Line LED Light, # MCL75RB, you will use the # A65PB Bracket for Single Wire Thin Line Light. The bracket has a black wire that the power wire on your trailer will connect. The light will ground to the trailer through the light bracket. If you are mounting to a steel frame then you will not need to install the trailers ground wire.
