Video Transcript for Optronics Trailer Lights A86PB Review

Speaker 1: Today we're taking a look at a two wire pigtail for Optronics trailer lights. This pigtail, with the two pronged plug, allows you to wire your trailer light to your trailer. It's designed for use with Optronics side markers, clearance, and utility lights. And it can be used for other trailer light brands as well. It features the male pin, two prong PL-10 molded plug. This connects to the back of the trailer light.And this is a two wire pigtail, so it has a two wire design.

The white wire is for ground, and it does come with a number 10 ring terminal already installed for easy connecting. And then the black wire's for power. The wires come off the plug at an angle, so you'll notice that they drop straight down, instead of coming straight off the back, or straight out. This really helps reduce the amount of strain placed on the wires. And the wire length is 18 inches long.

It's really easy to connect. This is the type of connection that it mates with. And you place it directly in the connection points. Push it in until it seats all the way. And that's all there is to it.

That's going to do it for the today's look at the two wire pigtail for Optronics trailer lights.

Pefect product for my boat trailer rewire project. fast shipping


Excellent service and exactly the right parts for my motorhome. Really appreciate etrailer's timely follow-up. Will definitely use again.


I recently had a tire blow out on my boat trailer and it took out the wiring for the fender-mounted marker lights. I spliced these two-pronged plugs into my existing wiring harness and they work great. They take up very little space and fit through the mounting holes on the trailer with no additional inletting needed.


I ordered this pigtail along with a replacement light and grommet after a tire blew out on my EZ Loader trailer and the flying rubber knocked the original light and grommet out into traffic where they were promptly crushed. It turns out I didn't need the pigtail because the old one still worked, but for as little as this cost I did not want to take the chance of not having the right parts to fix the light. Now I have an extra pigtail, just in case.


Easy to install were plug and play for my trailer. Only thing is not including the watertight connections for the splice maybe consider that in the future when the pig tails are bought. Most people do not have those type connectors and are sometimes hard to find.

by: is great. I could not find what I was looking for any where on the web. Tired of looking, and wanting one stop shopping, I went to I was unsure if what I was ordering would work for my application so I called etrailer. Bradly was a big help. He took my order and got everything shipped that day. Everything was exactly what I needed and as it was described. etrailer is now my first choice for trailer parts.


I installed these a year ago and they are still working fine. Replacing the light assemblies with LED probably reduced the draw that led to the demise of the old sockets but these are high quality replacements.


I purchased parts I needed to rewire my boat trailer from etrailer recently and I couldn’t be happier. Both orders arrived in a few days and were 100% correct. The parts I needed, though for an older boat, were matched exactly and my work on my trailer is done perfectly.

It’s nice to know this kind of service and company is around to help DIY’s!


Works as intended. Easy to install with basic tools. Used for rewiring some lighting on an enclosed cargo trailer.


parts ordered where as stated and quick delivery for my shorelander trailer marker lights and harness


etrailer has everything I needed to change all my trailer lights out and shipped them out quick. Lights were easy to install and very bright. Not one issue so far with them after a year. Way better than the standard halogen trailer lights.


George at etrailer supplied all of the parts to rewire and change all of my trailer lights to LED. The prices are good and the service is great. No problems and will use again for any of my lighting or towing needs.

Rick N. California


Proper replacement, came quick amd easy.


Worked perfect for my application. Easy to solder and fit my existing lights.

Easy M.


Still doing good - no problems


I used this pigtail in correcting a ground problem in a horse trailer. It's a quality product. The long pigtails are greatly appreciated.


Parts were easy to find on the website, prices were competitive and everything arrived within a few days - exactly as it should happen. I will use etrailer for all of my future trailer lighting needs.


Great price on tire and wheel combo, ordered LED lights also but haven't installed them yet. Placed my order on Sunday night, shipped out Monday morning received shipment Wednesday morning, great job.Randy


I used this to replace a damaged trailer light connector. It was an exact fit.


These marker lights are great and easily mounted and wired into my Shorelander trailer.


Replaced all the lights on my 2003 EZ loader, everything fits and works great at a price that is tough to beat.


Exactly what I needed. Super fast shipping. High quality item. Will be doing a lot more business with etrailer.


Easy to install, just what I needed without having to build your own harness.


Great price and fit my EZLoader trailer perfectly.


shipped on time, all items fit my boat trailer, good job e trailer.


Worked great to hook up my replacement light.

  • Troubleshooting 3 Malfunctioning Trailer Marker Lights # MC53RB on 2007 PJ Flat Bed Trailer
    The Optronics Round 2-Inch Sealed Flush Mount Trailer Clearance Light you referenced, part # MC53RB, can be installed either parallel- or series-wired. I was not able to find wiring information on the PJ Trailer website. Please note this incandescent light assembly is factory-sealed and does not have a user-replaceable bulb. The malfunction with all three of these lights could result from one of them failing in a series-wired configuration, from a bad ground, or it could result from a...

  • Polarity of Optronics Sealed Micro-Flex LED Trailer Side Marker # MCL50RB
    The Optronics Sealed Micro-Flex LED Trailer Side Marker # MCL50RB referenced in your question does have polarity, but the PL-10 Plug # A46PB that you also have is designed so that it can only be plugged in one way. This is essentially how you will know which way to plug the harness into the light. Since LEDs use diodes, if you were to somehow connect the harness backwards, the light simply would not work and you would just need to turn it around and plug it back in. On the harness itself,...

  • Recommended Round Trailer Marker Lights to Fit in 2-3/4 Mounting Hole
    The # MC56RB you were looking at is designed to fit in a 2-3/4" diameter hole and will have mounting holes 2-11/16" apart, so these will work for your 2011 PJ Dumper trailer. If you also need new pigtails for the wiring, you can use the # A86PB or the # A46PB (right angle pigtail). I've linked some review videos of these parts for you to have a look at.

  • Amber LED Clearance Lights or Side Marker Lights Color and Installation
    The LED Trailer Clearance/Side Marker Light - 4 Diode, 12.8 Volts - Round - Amber # MCL55A1224B will have an orange/yellow color. They do have a darker amber lens than some other options on the market. I've attached a video to assist. They will ship from our warehouse in St. Louis area (Wentzville). I've attached a review and an installation video to assist. These lights will use grommet # A54GB and wiring pigtail # A46PB or # A86PB.

  • What Optronics Parts do You Carry for My Trailer Light Replacement?
    I have an answer as to the availability of the parts you are looking for. Unfortunately, we do not carry the 146-181 or the MCL155RBP. However, we do carry the rest of the parts you list. Those are the following: - 2-Wire Pigtail for Optronics Trailer Lights - 2-Prong PL-10 Plug - 18" Lead # A86PB - Rubber Grommet for 4" Round Trailer Lights # A45GB - Light Guide LED Trailer Tail Light - Stop, Tail, Turn - Submersible # STL603RB - Right Angle 3-Wire Pigtail for Optronics Trailer Lights...

  • Looking for a 2 Inch Clearance Light That Has Clear Light and Clear Lens
    Optronics does have # UCL50CB which is a utility light that has a 2 inch diameter with a clear light and clear lens. This light operates off 12-24vdc, is waterpoof and has 9 LEDs. This lamp is meant to be used as a utility lamp only and is therefore not DOT compliant. To hook this utility light up you will need either the # A46PB which is the 6 inch lead straight plug or the # A86PB which is the 18 inch lead straight plug. The attached picture give you what the light looks like and also...

  • Does Optronics Mini Thin Line LED Marker/Clearance Light # AL191AB Use Grommet # A91GB
    Yes, the Optronics Mini Thin Line LED Marker/Clearance Light # AL191AB can be flush-mounted using the Optronics Flush Mount Grommet # A91GB. This PVC grommet will provide a degree of shock protection for the installed light and its rear opening allows easy access for wiring. If you prefer a surface-mount installation, you can instead use self-grounding mounting bracket # A91BB. The marker light # AL191AB has a 2-prong input on the back; you can use 6-inch pigtail plug # A46PB, or if you...

  • Diameter of Rough Opening Needed for Optronics MC57AB Trailer Clearance/Side Marker Light
    The lamp you've looked at, part # MC57AB is designed to be mounted in a 3 inch diameter rough opening. The lamp is designed to be used with a grommet, part # A55GB. You'd also need a # A86PB wiring pigtail. If you would reply with the dimension of the rough opening in the trailer where the light would mount, I'd be happy to make a suggestion. I've linked you to product description videos for the lamp, grommet and wiring pigtail.

  • Replacement Amber Clearance Light for Dutchman Kodiak
    The lenses on clearance lights are not generally removable as they are often "sonically sealed" such as the Optronics Trailer Clearance or Side Marker Light # MC57AB; this means they are submersible. Instead of buying a light and taking the lens off I strongly recommend an LED Trailer Clearance or Side Marker Light w/ Reflex Reflector # MCL59AB for your Dutchman trailer because an LED is a far better, much longer lasting option. You only need to make sure your existing lights have the...

  • Recommended Replacement Back Up Lights For a 2003 Ranger Trail Boat Trailer
    For your 2003 Ranger Trail Boat Trailer I recommend upgrading to the larger Optronics LED Backup Light # BUL12CB. These lights are submersible and have a clear lens with 6 bright LED's to improve visibility when backing up over your stock lights. These lights will require a cutout 6.85" long by 2.5" tall. A Grommet # a70gb is used to hold the light in place and they are wired with a Pigtail # A86PB. This will make it easier to replace lights in the future if they become damage.

  • Recommended Miro-Flex Clearance Lights With Clear Lens For Trailer
    We do offer Miro-Flex lights with clear lens for your trailer, but none of the Miro-Flex lights we carry are round with clear lens. The lights I recommend with a clear lens are part # MCL-50CRK. These lights have 3 LED diodes and come with the plug and grommet needed to install. For a round 2 inch Miro-Flex light, we offer the amber light, part # MCL50AB and the red light, part # MCL50RB. To mount these lights you would need the rubber grommet, part # a54gb, and you would need either...

  • Replacement Lens Availability for Reflect-O-Lite SAE-P-P1-68
    Unfortunately we do not have any replacement lenses for your Reflect-O-Lite lights. There may be some out there somewhere but the only solution we have for you would be to replace all of your lights. If you end up wanting to do this I can help you with replacement lights but it may be worth seeing if somewhere else has replacement lenses.

  • Will the Miro-Flex, 2 Inch Round, LED Trailer Light, # MCL50RB, Fit an Enclosed Snowmobile Trailer
    If adding the Optronics light, # MCL50RB, you will need about 2 inches of space behind your existing light for it to fit. The reason is the Optronics light is deeper including the pigtail mounting surface and the pigtail, # A86PB. If you have at least 2 inches of clearance, then this light will fit in your existing 2 inch diameter hole with grommet # A54GB. Light # MCL55RB is not quite as deep at 1 inch overall, so that is another option for you.

  • Availability of Rubber Grommet to Install Round Trailer Lamp in 3 Inch Rough Opening
    We don't have a grommet that will secure a 2 inch lamp in a 3 inch rough opening, but the Optronics # A55GB rubber grommet will work with a 2-1/2 inch diameter lamp like the # MC57AB you'd looked at. The 2-1/2 inch diameter lamp is also available in red as part # MC57RB. Each lamp would use a # A86PB pigtail, which is sold separately.

    For the 6" oval hole in the Buyers Products Tail Light Mounting Box # 337LB383SL you will need the PVC Grommet # a70gb and a Optronics LED Trailer Tail Light # STL72RB. A 3-Wire Pigtail # A45PB is needed for connecting to the light. The 2" hole on the side will use the 2" Round Grommet # A54GB and Miro-Flex LED Clearance or Side Marker Light # MCL50RB. A 2-Wire Pigtail # A86PB is needed for connecting to this light.

  • Replacement Boat Trailer Lights for 2-3/4" Rough Cutout and 2-1/4" Grommet
    I have a solution for you, but we do not have any replacement lights that will fit in those grommets. Instead, you can use the LED Clearance or Side Marker Light # MCL002AXB (amber) and # MCL002RXB, which require a rough cutout dimension of 2-3/4", so they'll fit in your existing holes and provide you with the light solution you're looking for. These are waterproof LED lights so they're the perfect solution for a boat trailer as long as the rest of your lights are already LED. If your...
