Working great just what I needed!!

I have been re-building some Vetter bags for my '82 Honda 900C and decided to add some rear lighting. I took a chance on etrailer and ordered 2 LED side markers. These folks are definitely into great customer service and fair prices. I admit I am spoiled from Amazon 2 day shipping, but I did receive my order in less then a week...not bad at all. I asked a question a few days after I ordered and got an immediate and friendly response. I installed my new lights on the left bag...they fit just as expected, and are very bright! I already ordered 2 more for the right side. Keep up the good work etrailer!

  • 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 Kit #...

  • Wiring Pigtail and Mounting Bracket Options For Installing Thinline LED Clearance And Marker Lights
    The Thinline LED Clearance and Side Marker Light # AL91AB require certain mounting brackets and plugs that are either already installed on the trailer or are available separately. A Right Angle 2-Wire Pigtail # A46PB will work with the Grommet # A91GB if you are looking to recess the light. Or Mount Brackets # A91OB and # A91BOB if you want to mount them on a surface with the wiring running behind the bracket. The Plug - Single Wire # A91LW is used for Mounting Brackets # A91BB and...

  • Looking for LED Version of # AL91RB Mini Rectangular Clearance/Side Marker Lamp
    You bet we do! For the LED version, you'll need part # AL91RB. The lamp can be grommet mounted using # A91GB or surface mounted using a self grounding base like # A91BB for black/ # A91CB for chrome or a standard base like part # A91BOB for black/ # A91OB for chrome. If you use a self grounding base, use the single wire pigtail, part # A91LW or for the standard base, use the two wire pigtail, part # A49PB.

    We do have the parts you need to complete installation of the light.

  • 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.

  • 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 #...

  • 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.

  • Are Mounting Brackets Needed To Install Optronics LED Trailer Clearance Lights # AL91RB
    For installation of the Optronics LED Trailer Clearance Lights, part # AL91RB, you will need to use an Optronics Mounting Bracket. You can use either the Optronics Black Mounting Bracket, part # A91BB, or the Chrome Mounting Bracket, part # A91CB. The brackets are sold individually, so you will just need to order the same quantity as the number of lights you have. I have linked a video that show the installation of the Optronics AL91 Series Lights.

  • 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.

  • 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 Bracket...

  • 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.

  • Are Clearance Lights Needed on a Snowmobile Trailer
    To equip your snowmobile trailer with a basic lighting setup, you would need amber front side marker lights and red rear side marker lights. A basic trailer would require a minimum of two each, with the front lights as far forward as possible and the rear lights as far back as possible. The # TLK36RK trailer light kit includes the required amber front marker lights , but you could also add matching red clearance lights # A91RB with chrome bases # A91CB. I would also recommend using...

  • Red Optronics Clearance Light Needed and Matching Chrome Mounting Bracket
    The Red version of the Sealed, Mini Rectangular LED Trailer Clearance, Side Marker Light # AL91CAB from Optronics is found as part # AL91RB on our site. The Chrome mounting bracket for both lights is part # A91CB and works with 90 Series or 91 Series Optronics lights.

  • Mounting Hardware for Optronics Mounting Bracket
    The Optronics Mounting Bracket # A91CB grounds through the mounting hardware. So whatever hardware you use, whether screws or pop rivets, make sure it's made of a conductive metal. The hardware we generally recommend is self-tapping screws # 1131832 but pop rivets should work just fine.

  • Is There A Grommet Available To Go With The Optronics Dragons Eye LED Lights
    You are correct in that Optronics does not make a gasket to go with their line of dragons eye LED lights. If you are wanting marker lights with a grommet or gasket we do have the Optronics micro flex LEDs # AL191AB in amber and # AL191RB in red. These can be brackets that come in either black # A91BB or chrome # A91CB.

  • 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.
