Video Transcript for Review of Optronics Trailer Lights - A91LW

Today, we're going take a look at the 12 inch long single wire plug for the A91 and AL91 series trailer clearance side marker lights. This is a single wire molded plug with a 12 inch lead for use with the series A91 AL91 and even the LP91 lights. This plug, along with the lighter to be used with a surface mount base, to complete the installation of the light to your trailer. The surface mount base is sold separately. We do list that on this product page as a related product, but basically what happens is the surface mount base that the light attaches to will ground that light through the mounting hardware on the base so it only requires a single power wire for operation and it does have a 12 inch lead.You can see if I put the ruler down here. It's going to give you a 12 inch lead for the power connection.

Now cross-reference manufacturer, this wiring plug will work as an exact replacement for the Unibond PT9011, the Westfall 106334, the Truck-Lite 96913, and the Peterson 154-49. But that should do it for the review on the 12 inch long single wire plug for the A91 and AL91 series trailer clearance side marker lights.

I ordered the Thinline LED Clearance and Side Marker lights, rubber grommets and lead wires from etrailer.com to replace the lights on my trailer and I am very happy with my purchase! The lights install easily and look great as you can see! And the light assembly is sealed to prevent moisture from getting in! Make sure you order 2 wires with each light because they plug directly into the LED assembly - the ground connection is not made through the body of the light. Thanks to George and Nicole for their help! 565637

- A91LW
by:

Be advised that if you use some of the marker lights, such as the A91 & AL91 series, they require smaller than standard plug-in pins. The normal sized electrical plug-ins, will not fit. These wire whips with plugs address that problem perfectly. Be sure to use plenty of di-electric silicone grease on all connections that will get submerged. 191065

Here again, I am using it for a different lite system. Fit is prefect and easier to install. The original had a double wire hookup, which took a large hole for the unit to fit in. The single wire is a real small hole, making it simpler to line everything up. 15496

Ask the Experts about this Optronics Accessories and Parts

Do you have a question about this Accessories and Part?


  • Will LED Clearance Light Work With One Wire
  • Yes, the Thinline LED Clearance and Side Marker Light - Submersible # AL91AB will work with your single power wire, as it uses a 2-wire (one for power, one for ground) pigtail or 1-wire pigtail with a self-grounding bracket. To mount this light you have a couple options. The first is the Mounting Bracket # A91BOB with Right Angle 2-Wire Pigtail # A46PB; you'd also want to use the Self-Tapping Screw # 1131832. Your other option to mount this light is to use Self-Grounding Mounting...

  • Parts Needed to Install Optronics Submersible Red LED Clearance and Side Marker Light AL91RB
  • The Optronics Thinline Submersible Red LED Clearance and Side Marker Light # AL91RB installs using a base, part # A91BOB in black or part # A91OB in chrome finish. A 2-wire pigtail # A46PB will allow for electrical installation. The white wire on the pigtail is ground. If your original light used only 1 wire then its base provided the ground connection. In this case you can use the self-grounding base # A91BB in black or # A91CB in chrome finish. In this case you will use Single Wire...

  • Replacement Amber Clearance Light for a Peterson PM 150
  • Sealed lights would have to be replaced since there is not easy way to get them open and maintain functionality of the light. Your light looks similar to # A91AB. This light measures 2-1/2 inches across, 1-3/16 inches tall and 7/8 inches deep. It mounts in base # A91BB and can use harness # A91LW.

  • Is there a Grommet for Peterson Clearance Light # M152A
  • For a rubber grommet that will fit the Peterson clearance light # M152A you can use # A91GB. If you are looking for the plastic base we do not carry that particular model and in that case I recommend switching to light # A91AB and using bracket # A91BB with power wire # A91LW (the light grounds through one of the mounting screws with this light and bracket combination).

  • Replacement LED Taillight Recommendation for 2002 Shoreland'r Profile 2000 Boat Trailer
  • We do indeed have some LED taillights that'd work great on your boat trailer. I'd recommend # STL57RB for the driver side and # STL56RB for the passenger side. These lamps measure 6-1/16 x 2-5/8 inches, and would work well on your trailer. As you can see in the photo provided by one of our customers, the taillight works well on a Shoreland'r trailer. As long as they're still working okay, you certainly may leave the existing fender running lights in place. If you decide you want to...

  • Replacement 2-1/2 x 1-1/4 Inch Amber and Red Trailer Clearance Lights and Chrome Base
  • Based on your picture it looks like you are in need of some replacement lights and a bracket. It looks like you will need amber light # A91AB, red light # A91RB, and bracket # A91CB. And if you need the single wire (since the lights will ground through the bracket and mounting hardware) use # A91LW.

  • Replacement Boat Trailer Clearance Light with SAE P2 91 DOT on the Lens
  • The number on the lens that you see is the lens rating, not a part number so it is difficult to go by that number. There might be a part number on the back of the light housing. Otherwise it would be easiest to go by the dimensions of the light. For example light # A91RB does have the same lens rating. It would use a base such as # A91BB and wiring harness # A91LW for the power wire.

But first, sealed, Miro Flex, Mini Thin Line LED Marker or Clearance Light # AL191AB does not include a base or wiring harness. We have the compatible bases listed as related products on the right hand side of its product page.

  • How to Wire up the Thinline LED Clearance and Side Marker Light to Single Wire Trailer
  • To use the # AL91RB on a trailer that has one wire for the power wire and then grounds through the mounting bracket would only require the bracket part # A91BB for the bracket and then part # A91LW for a single wire connector.

  • What Wiring and Accessories are Needed For Side Marker Trailer Light # A91AB
  • The Sealed, Mini Rectangular Trailer Clearance and Side Marker Light, # A91AB, requires a pigtail and a mounting bracket. The pigtail is # A91LW. I have included a link to a video showing a typical installation for you. For a bracket, there are a couple of options. For black, use # A91BB. For a chrome finish, use # A91CB.

  • Looking for Boat Trailer Clearance Light to Replace Signal Stat 1500
  • According to my Optronics representative, the # AL91RB marker/clearance light you mentioned is a direct replacement for the Truck-Lite 15 series. The Signal Stat 1500 is how Truck-Lite refers to the same lamp in its LED version. A mounting bezel is available, part # A91BB for black or # A91CB for chrome plated ABS. If either one of these self-grounding bezels is used, use a # A91LW pigtail. If a non grounding bezel or bracket is used, a two wire pigtail like part # A46PB would be needed.

  • Replacement Amber Mini Trailer Clearance Light For Wesbar 3395
  • We have just what you are looking for. The replacement clearance light we offer is the Optronics Mini Rectangular Clearance Light, part # A91AB. This is an amber light that measures 2-1/2 inches long x 1-3/16 inches wide x 7/8 inch deep. This light requires the # A91LW pigtail to complete the wiring and a mounting bracket. The bracket is available in black, part # A91BB. For a chrome finish, use # A91CB.

  • Replacement Tailgate Marker Lights for 1984 GMC C-Series Dually Pickup
  • Yes, from what I found, you can use # AL91RB LED lights to replace the five original incandescent tailgate lights on your 1984 GMC C-Series Dually Pickup. These are standard size clearance lights (2-1/2 x 1-3/16) that were used on a variety of different trailer and some truck OEM applications and were sold under a number of brand names. Keep in mind that these lights don't have wires coming out the back, so in order to install them you'll also need a mounting bracket # A91BB to provide...

  • Wire Gauge for Single 12" Wire for A91 and AL91 Series Trailer Clearance, Side Marker Lights
  • I went out to the warehouse and pulled a single wire plug # A91LW to determine the wire gauge used. It is an 18 gauge wire so very small and thin. This is because it is designed for trailer light applications that do not draw a lot of power so a larger gauge isn't needed.

  • Is Female Plug Available For Single Wire Male Plug For A91 And AL91 Series Trailer Lights
  • The single wire plug # A91LW is designed to plug into a light that has the female plug already installed on the back of the trailer light. The # A91LW has a 12 inch lead wire with the male plug attached. Many of the Series 91 lights have two female plugs which would use the standard 2-prong wire like part # A46PB. If you use a self-grounding bracket like part # A91BB for a series 90 or 91 trailer light, the single wire # A91LW can be used.

  • Dimensions of Bargman #99 Series Mini LED Light
  • No; from my research it looks like the Truck-Lite 15 Series is 2-1/2" long and roughly 1-3/16" tall. The Bargman #99 Series Mini LED Lights # 42-99-401 measure 2-1/8" x 1-1/8" x 1-1/16". The closest light we have to the dimensions of the Truck-Lite are the Optronics # AL91RB, which are submersible LED lights that measure 2-1/2" long x 1-3/16" wide x 7/8" deep. For a surface mount to install this light you need Self-Grounding Bracket # A91BB and Single-Wire Plug # A91LW

  • Trailer Clearance Light Part # A91RB Installation
  • To connect the Optronics Red Mini Rectangular Trailer Clearance and Side Marker Light to your existing trailer wiring, you would need the pigtail which is part # A91LW if you were using the self grounding mounting bracket, part # A91BB. If you were using some sort of other bracket that is not self grounding, a two wire pigtail is offered, part # A46PB.

  • How Does Clearance Light Included with Trailer Light Kit part # TL16RK Wire to Trailer
  • The clearance lights of the # TL16RK are the part # A91AB with the bracket part # A91CB. The assembly grounds through the mounting hardware and the single wire part # A91LW that comes with it runs to the running light circuit of the trailer like you mentioned.

  • Could Optronics Amber LED Trailer Turn Signals be Used as Motorcycle Turn Signals
  • The Optronics Trailer Light # AL191AB that you referenced would make an excellent turn signal for your motorcycle. The LED diodes are very bright and should provide you with very visible turn signal. The chrome bezel to go along with it would be the Chrome Mounting Bracket # A91CB. This product would normally ground through the mounting bolts, but since you would be mounting this in a fiberglass bag you would need to ground it using an Optronics Single Wire Ground # A91LW.

  • Optronics Amber Clearance LED Clearance Light Recommendation
  • If you are looking for a replacement clearance light for your trailer you are going to want to use an amber bulb like the Optronics Trailer Lights # AL91CAB. A white bulb would not be a good choice as a a clearance light, since in most cases it is required by law that you use an amber or red lens. I attached a review video for this product for you to check out also. You may also be interested in a Black Mounting Bracket # A91BB and an Optronics Wire Plug for the AL91 Clearance Lights...

  • Wiring Pigtail Harness for Sealed, Mini Rectangular Trailer Clearance and Side Marker Light A91RB

  • Replacement Wiring Needed for a 6 x 10 foot Trailer
  • We don't actually manufacture our wiring harnesses, but we do have some options available for you. You can use the Wesbar Wiring Harness # 002220 to replace the wiring on your 6 x 10 aluminum trailer. To complete the installation you will only need a Ring Terminal # DW05702-1 and Butt Connectors, part # DW05744-5 for 5 or part # DW05744-10 for 10. Just simply splice in the lights that you have into the wiring. If you don't already have lights then you can use the Trailer Light...

  • How to Determine if Amber Clearance Light Will Work on Trailer
  • In order to determine if the Thinline LED Clearance and Side Marker Light # AL91AB will fit your trailer you simply need to measure your light and see if it matches; this light is 2-1/2" long x 1-3/16" wide x 7/8" deep. It is also a great option because it can be either recess or surface mounted. For a surface mount you will use Self-Grounding Mounting Bracket # A91BOB with Plug # A91LW. For a recess mount you will use Grommet # A91GB with Right Angle 2-Wire Pigtail # A46PB. I...
