Great product! My right brake/turn signal stopped working on my trailer, so I purchased a new ST70RB 6-1/2" oval trailer light, along with the wiring plug and grommet, installed them in about 30 min, and it works great! The package arrived quickly and was packed nicely. I found out my fuse was blown on my 2016 Traverse for the right trailer stop/turn signal, but that was most likely from the old light which I think was leaking. I didn't know there was a fuse just for that so I learned something new. I will definitely purchase trailer products again from etrailer.com!

I love shopping at Etrailer because it's easy to find products and the way products have measurements and video review makes everything easy. Plus the fast shipping is outstanding.

Lights they recommend use a grommet. Very hard to get light in grommet in bracket. I will probably be returning on light and grommet. I've tried everything short of using hammer to get light in grommet. Would have thought bolt/screw on light would have been recommended

The amber led lights I received were great and I installed them in the front of my 2002 Pontiac Firebird cuz I clipped another deer and ran over a raccoon in the same night and they took out my front lights again. So, rather than try to purchase an original set of turn signal and fog light assemblies along with the expensive bulbs, I converted it over to led and it is a great upgrade for an older car. The problem is that the three color coded wires came with no directions that told me which wire was ground, park, or turn. I had to figure it out as the color codes are different on my car. I would send a pic, but it is on my cellphone.

With the trailer lights you really need this PIG TAIL. You can make it work, but this is so much easier and is water proof. Picture is back side of the panel where the PIG TAIL is sticking threw. This will get coated with under coating when it all done. John

Ordered replacement lights for my trailer turn brake running light went with the led replacement car incandescent and they fit perfectly. I also ordered the rubber grommet part and it was perfect as well. I did order the wiring but did not use yet in my tool kit. Service was great as was the follow up. Great job folks as an avid fisherman with no time to mess around this was a great experience! Thank you I will use you and recommend strongly! Jim

I replaced the conventional lamps in my 1990 Peterbilt Midranger box truck. The change out was easy. The previous lamps were troublesome because of vibration, moisture / road salt, causing them to not light. I used these pigtails to plug into the LED lamps I purchased from eTrailer, to easily install the new lamps, splicing into the existing wiring harness in the truck. The thing to know, is the unique color coding: White is Ground, and has a convenient lug on it to attach under one of the mounting screws. Red is for the stop/turn signal, and Black is for tail lights.

I called and spoke with Lisa D for a special order product that E-trailer needed to order directly from the manufacturer and have it added to their website, and Lisa D kept me updated every step of the way. She got the products order and shipped with a very quick turn around time, which was great b/c I couldn't find any company that could assist me with ordering the lights that i wanted. Very pleased with E-Trailer and Lisa D.

  • Wiring Configuration of 3 Pins on Optronics 3-Wire Pigtail # A45PB
    I have attached a diagram below that points out the function of each pin on the Optronics 3-Wire Pigtail # A45PB that you can use for reference. On the wires themselves the white wire is for ground, the red wire is for turn/brake signal, and the black wire is for running lights.

  • Converting a 3-Way Northland Truck Camper Wiring Harness to a 4-Way Flat
    What you can do is to use the Quick FixTM 4 Pole Flat Car and Trailer Ends, # 48195, and not use one of the pins since you only have three wires that need to be connected. You can then use the wire you need inside of them as needed. The wires that run to the battery are most likely 10 gauge like # 10-1-1. The remaining wire is probably a 16 gauge like # DW02359-1.

  • Recommended Three-Prong Wiring Plug For Optronics Sealed Round LED Trailer Light # STL43RB

  • What is the Wire Gauge Size for the Optronics 3-Wire Pigtail # A45PB
    The wire gauge for the Optronics 3-Wire Pigtail for Sealed Trailer Lights # A45PB is 20 awg. The diameter of a 20 awg wire is .032 inches. Optronics does not offer waterproof shrink connectors, however, check your local big box hardware or auto parts store.

  • Troubleshooting 3 Wire LED Tail Light Installation
    Your old two wire lights definitely used the mounting screw as the ground. Your new LED lights with 3 wires will be easy to transition. You will connect the running light wire and the turn/stop wire just as before, and then you will run the ground wire directly to your steel frame. A bad ground is most likely the issue with your fuses blowing. Make sure your ground wire to your frame is metal on metal and your 3 wire LED lights like # STL43RB with 3 wire pigtail similar to the # A45PB....

  • What Do Trailer Taillight Colors White, Red, and Black Mean
    You are correct the white wire is the ground circuit, the red wire is the stop/turn circuit and the black is the running light. This is the industry standard for trailer lighting colors like what comes with the harness part # A45PB.

  • Which Type of Pigtail Lead to Use with Optronics Round LED Trailer Stop/Turn/Tail Light # STL42RB
    The Round LED Trailer Stop/Turn/Tail Light # STL42RB from Optronics uses an industry-standard 3-prong plug. The two plugs you referenced, the Straight 3-Wire Pigtail # A45PB and the Right Angle 3-Wire Pigtail # A47PB, both will fit this light assembly. You choice will just be a matter of preference depending on the amount of clearance you have behind the light's mounting points. If space is tight then the right angle plug might be a better option. I suggest you apply dielectric grease,...

  • Long 2-Wire Pigtail Recommendation
    Check out the Two-Wire Straight Pigtail # A46P75B, this 2-wire pig tail is 75 inches. Since you said you need much more than 6 feet this may not be quite long enough at 6.25 feet long, but it is the longest one we offer.

For a grommet you will want the PVC Grommet # a70gb and to wire it you will need the 3-Wire Pigtail for Optronics Trailer Lights # A45PB.

  • Troubleshooting Reverse Lights Not Working on a 1997 Northland Truck Camper, 11-footer
    First visually inpect the condition of the bulbs and the grounds of the lights that aren't working. If they look good then you could use a jumper wire like you said to test to see if the lights will illuminate. If so, then you know the problem is somewhere in the wiring. It could be that the lights aren't connected, if they have never worked it could be that they were never connected initially.

    The Optronics Fleet LED Trailer Tail Lights # TLL12RK are a slightly longer light so they aren't a replacement, but we do have the LED replacement you need for the Optronics # ST70RB. That part is the Optronics LED Trailer Tail Light # STL72RB. This light uses the same PVC Grommet # a70gb with the 3-wire Pigtail # A45PB or # A47PB (right angle pigtail) for installation.

  • 4 Inch Diameter Trailer Tail Light Options
    We do have a number of options for trailer tail lights that are 4 inches in diameter, although the standard for these lights is a 3-wire system: ground, turn signal, and tail light. Your lights may have grounded through the mounting hardware, but these lights will use a wire for that. The options I recommend are LED because they are going to last much, much longer and have a lesser power draw than incandescent lights - Peterson LumenX LED Trailer Tail Light - Stop, Tail, Turn # M824R-7...

It works with the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB.

  • Plugs Needed for the Fusion LED Trailer Tail Light # STL211RCB
    At first I thought that this light had 2 places for the 3 terminal plugs but if you check out the attached picture of the Fusion LED Trailer Tail Light # STL211RCB you can see that one plug has 3 prongs (for tail light functions) and one plug has 2 prongs (for reverse light function). If you are just needing standard plugs then you would use part # A45CB for the 2 prongs and part # A45PB for the 3 prongs. These are also available at right angles with parts # A49PB and # A47PB respectively.

For something with a flexible rubber mount, you'd be wanting a grommet mount lamp, like # STL70RB which would mount using the separately available # A70GB which would mount in a 6-11/16 x 2-5/8 inch rough opening and would use a # A45PB 3 prong plug.
