Video Transcript for Optronics Right Angle 3-Wire Pigtail Review

Today on our Gooseneck Flatbed Utility Trailer, well be installing the Optronics Right Angle 3-Wire Pigtail for Sealed Trailer Stop, Turn and Tail Lights, part number A47PB. Now youll see heres what our pigtail looks like. The white wire with the ring terminals the ground, the red wire is for the stop and turn signal and the black wire is for the running light circuit. Now, because we have 2 taillights right next to each other, were going to go ahead and tie two 3-wire pigtails together, so well be connecting both reds together and both blacks together using a heat shrink style butt connector. The butt connector part number well be using is DW05744-10. Now well go ahead and connect both of our red wires, as well as the black wires using the heat shrinkable butt connector. Well then be connecting the green wire with the red wires. Since theres an extra side marker light just outside where these 2 taillights are, were going to go ahead and tie an extra brown wire or running light circuit wire in when we make our connection for the running light circuit.

So, well be adding an extra brown wire in where we tie into our 2 black wires. Well go ahead and take our brown wire, which is a running light circuit, after weve added the additional piece of wire in to tie in our side marker light, well go ahead and connect these 2 to the black wires, again using that butt connector. Once the connections are made, we use our heat gun and seal up the butt connectors. Once theyve cooled a little, well go ahead and wrap them in some electrical tape, just for a little extra protection. Then well need to take both of the white wires with the ring terminal on it as these are the grounds. Well go ahead and take a self-tapping screw and attach it to our trailer. Now, because of the thickness of metal on our trailer, were going to go ahead and put the screw in first to get a hole in the trailer.

Once our holes there, well back it out and then well put it on both of the ring terminals and then snug it down, so that the white wires are grounded to the trailer. Now, for test purposes, well go ahead and take a stop, turn and tail light that matches our plug. Well plug it in and then well test our running lights, as well as the stop and turn signal. As you can see here, our running lights are functioning properly, as well as the stop and turn and thats all there is to it for wiring up the Optronics Right Angle 3-Wire Pigtail for Sealed Trailer Stop, Turn and Tail Lights, part number A47PB on our gooseneck flatbed utility trailer. .

the Malone roof racks solved two problems for me. one problem was how to carry items too long to fit inside a Dodge Journey. The other problem was how to do it on the cheap. I looked locally and online for sturdy racks only to find they were more expensive than I was willing to accept. these racks fit my budget, my car and my purpose. Very happy with these. Oh, since this purchase I bought another set for another Dodge Journey. 703829

The products are quality, with competitive pricing. etrailer.com delivered as promised, it was our local delivery that delayed sending the product out to my home, but one call to Pat, and the issue was immediately resolved, and I had the product that night!

Like the product. Fairly easily to install. Liked that the taillights are brighter and the stop light lets the people behind me that I am stepping on the brakes. Now I just need to tackle the back up lights and a couple of more items that I need to order later. 691163

Recently it was time to replace/ upgrade my boat trailer rear lights. I found exactly what I was looking for at etrailer. The parts I ordered were well described and fit exactly right for my application. I also ordered the wire pigtail connectors as I was adding lights with an integrated backup lamp. Installation was a breeze and all the parts seem to be high quality. I will definitely buy more items of etrailer in the future. Thanks for the parts. 680699

Ask the Experts about this Optronics Accessories and Parts

  • Adding Tail Lights to a Cargo Carrier at the Back of a Travel Trailer
    First for a light kit that is designed for certain cargo carriers you can use # 98174LED. It uses a 4-Way connector and since the brake and turn signal lights on your trailer are combined (based on the fact that it uses a 7-Way connector) To add a 4-Way you can tap into the trailer's lights using # 118001. And to mount it at the back of the trailer you can use bracket # 18144. Depending on the cargo carrier you have you may also need 2 of bracket # BK70BB to attach the lights.

  • 90 Degree Wiring Harness Recommendation for Wesbar Lights # 271584 and # 271585
    The recommended 90 degree pigtail harness for the Wesbar Lights # 271584 and # 271585 is the # 719063. There is a good chance the Optronics one would work, but since the two haven't been test with each other and the # 719063 is available I wouldn't recommend it for you.

  • What is the Wire Gauge for Right Angle 3-Wire Pigtail # A47PB
    I went out to the warehouse to check the wire gauge on Right Angle 3-Wire Pigtail # A47PB. Each of the 3 wires is 18 gauge. At 10 inches in length 18 gauge automotive-grade wire can handle a maximum of approximately 15 amps which is much more than any light that it goes with pigtail A47PB.

  • Functions of the Three Wires on Trailer Taillight Harness A47PB
    Our three wire lights like what the harness part # A47PB is designed to fit have the white wire as ground, the black wire for tail light, and the red wire for stop/turn signal. That covers all of the standard trailer taillight functions.

  • Replacement Pigtail Plugs for Trailer Lighting
    For a 3-prong pigtail plug for a light like the Optronics Trailer Light # ST70RB that you referenced you can use part # A47PB or for a 2-prong use part # A49PB. All such items are shown on the linked page. Corrosion can be prevented by applying dielectric grease # 11755 to the connectors before seating them together. Dielectric grease helps prevent the entry of moisture and dirt that can lead to corrosion which will interfere with signal transmission.

  • Replacement 3-Wire Pigtail For Tail Light On 2011 TrailStar Boat Trailer
    We offer a couple different 3-way pigtails that are typically used for a sealed trailer tail light that may work for you. The first is a right angle 3-wire plug, part # A47PB. It has three wires, a red, black, and white. The red is a turn signal, the black is the tail signal and the white has a ring terminal on it and is designed to be the ground that needs to be attached to a clean metal surface. The 3-way plug is designed to plug into the back of a sealed light. For a straight 3-wire...

  • How Do I Wire a 3 Wire Pigtail # A47PB to a Trailer that has 2 Tail Light Wires
    You will wire the black and red wires from the 3 wire pig tail to the two wires from your trailer, the red wire will be wired to the turn signal circuit and the black wire will wire to the tail light circuit. The third (white) wire from the pig tail is the ground wire and will need to be attached to a good clean ground on your trailer.

  • What is the Wire Gauge Used for Right Angle 3-Wire Pigtail # A47PB
    The wires for Right Angle 3-Wire Pigtail # A47PB are 18 gauge. I am not sure which oval lights you are referring to. Any that would take this pigtail do not have wires. If you can tell me a specific part number I can check the wire gauges for it as well.

  • Repelling Moisture and Corrosion Using Right Angle 3-Wire Pigtail # A47PB For Trailer Tail Lights
    Once the right angle pig tail harness, # A47PB, is plugged in it will seal up nicely but for additional protection from moisture and corrosion apply some dielectric grease, # 11755, to the pins before plugging the harness into the light. Dielectric grease is hydrophobic and will repel moisture and resist corrosion.

  • Replacement Trailer Lights with Numbers PM 143 and PM 421
    Although the DOT numbers you gave me are codes for what testing was done on the lights, I do have a solution for you. For your 2-1/2" round clearance light we have the Peterson Piranha LED Light # 162R with the wiring and grommet as part # 162-18K. We have had people ask about your PM 421 light before and have found that the Optronics # STL22RB with the grommet # a70gb are perfect LED replacements. If you need new pigtail wiring for these you can use part # A45PB or the angled part...

  • LED Tail Lights for a Ranger Trail XT188 Boat Trailer
    I checked with Ranger and the current generation of the Trailer RT188 uses the 6 inch oval tail lights. For those the Miro-Flex Trailer Tail Light # STL22RB is a great option for an LED upgrade. These lights use pigtail # A47PB and will fit the mounts currently on the trailer. If your trailer has different tail lights, such as those that hang from studs then # STL16RB and # STL17RB are great options for that mounting style. If neither of the recommendations above are the light style...

  • Oval LED Trailer Tail and Backup Light that Mounts with a Grommet
    The closest match would be # STL211RB. It doesn't have a clear lens or Glo feature though. The grommet for this light is # A70GB and you would need pigtails # A47PB and # A49PB to plug into the back of it.

  • Is Trailer Light STL22RB Replacement for PM 421 Light on Trailer
    Yes, the connection on the Micro-Flex Trailer Tail Light - Stop, Tail, Turn - LED light, part # STL22RB, is compatible with the PM 421 lights that you currently have on your Silver Star horse trailer. You will not need a new pigtail since it uses the same pigtail. However if you do need to replace a pigtail we have the 90 degree option, part # A47PB, and the regular option, part # A45PB. We also carry a replacement grommet if you need that as well, this would be part # A70GB but if yours...

  • Replacement Tail Light for Wesbar 108121
    The Wesbar 108121 has been discontinued but the Optronics Trailer Tail Light - Stop, Turn, Tail - Submersible - Incandescent - Oval - Red Lens # ST70RB is the ideal replacement. It works with the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB. This light will use the standard 3 prong plug that if you need a replacement is # A45PB or # A47PB for the 90 degree connector.

  • Availability of 3-Prong Pigtail Plugs with Load Resistors
    The Optronics Round LED Trailer Stop, Turn and Tail Light # STL42RB does use a 3-prong plug for electrical connection. We offer right-angle 10-inch pigtail plug # A47PB and straight pigtail plug # A45PB. Neither of these includes a load resistor, which can be required on some wiring systems to mimic the higher electrical resistance of standard incandescent lights. Some turn signals will hyper-flash when used with LED lights because the wiring does not "see" the load from the super-high-efficiency...

  • Is the Bargman LED Trailer Tail Light a Quantity of One or Two Lights
    The Bargman LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 48 Diodes # 47-06-404 is a quantity of one light. It's large number of diodes makes this one of the best trailer lights on the market. It is recessed mount with Grommet # 40-06-020 and wires in with Pigtail # 40-00-003 or # 40-00-004. Additionally, there are more budget-friendly options that are a similar size than the Bargman. For example, I recommend checking out the Optronics LED Trailer Tail light - Stop, Tail,...

  • Depth Dimension of Optronics Miro-Flex LED Trailer Stop/Turn/Tail Light STL35RB
    The actual depth of the Optronics Miro-Flex LED Trailer Stop/Turn/Tail Light # STL35RB is 2-5/16-inches, as shown in the linked diagram which includes overall dimensions too, but you will also need to allow for the right-angle plug # A47PB which will add another inch. This light is intended for installation using rubber grommet # A33GB.

  • 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.

  • Recommended LED Replacement Lights for 2005 Damon Daybreak Motorhome with Load Resistors
    The Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB will work great on your motorhome. You will simply need to use the wiring pigtail # A47PB for each light. You will simply need the butt connectors # DW05744-5. On some vehicles, when switching to LED lights, there is a load resistor needed to prevent hyperflashing but this is not always needed. If you do end up needing a load resistor, I recommend the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 #...

  • Is Optronics LED Trailer Tail Light # STL42RB Sold Individually or In Pairs
    The Optronics LED Trailer Tail Light # STL42RB is sold individually. If you needed a pair you'd need to order a quantity of two of these. For a wiring harness you'd then need the part # A47PB and for a mounting bracket part # BK45BB and you'd be set.

  • Replacement Round LED Trailer Tail Light for a Peterson Round Tail Light
    The Peterson part number # 420-15 that you referenced is a replacement lens for the Peterson Round Trailer Tail Light # 431800 which has a 3-3/4" diameter. Although we don't have an exact match to this in LED we do have slightly larger sizes of round tail lights that come as LED. If you are wanting to go with one from Peterson then we have the LED Trailer Light # M826R-7 which has an overall diameter of 5-1/2" but the light diameter is only 4-1/4".

  • Picking Out Replacement Trailer Taillights for 2009 Cargo Pro Trailer
    I tried pulling up pictures of your 2009 Cargo Pro Trailer on Google and from what I was able to find it looks like your trailer uses taillights like the # TLL12RK which are a recessed mount that come with a grommet. So for a single light you'd want the part # STL72RB with the grommet # A70GB and if you need a pigtail harness part # A47PB. If you have something different email be back a picture and I'll see what is the best match for it.

  • How to Ground Trailer Lights & Other Electrical Components on Fiberglass Trailer
    A trailer stop/turn/tail light such as Optronics LED Trailer Tail Light # STL513RB which takes a 3-prong pigtail plug like # A47PB will require you to run a separate ground wire from its white ground pigtail to either the steel trailer frame or to the 7-way's ground in order to operate. Some trailer lights use their mounting hardware to provide the ground connection but these would not work on your fiberglass trailer without making a separate ground connection to the frame.

    If you have existing trailer light wiring, it is not necessary to run additional wiring from your new LED light to your 7-way connector. You can splice into the wiring that feeds your current lights but will need the following pigtail leads. You will need a right angle # A47PB or a straight # A45PB 3-wire pigtail lead and a 2-wire pigtail # A45CB to install the Optronics Stop-Tail-Turn-Backup Trailer Tail Light # STL211RB.

    We have 6-1/2 inch oval LED lights that are very bright, that are typically referred to as 6 inch lights in the trailer industry.

They have a very clean look and are sonically sealed so they can handle all the weather thrown at them. They require a recessed mount # a70gb, and a 2-prong...

  • Installation of LED Trailer Tail Lights with 4 Wires
    Without knowing exactly what lights you have, it is difficult to help based on color. Most of our LED lights use a pigtail with 3 wires # A47PB with the red being turn signal and brake, the black for tail/running light, and the white for ground. The only way to tell your unique light function is to connect the ground which I would assume is the white wire, and then test the other functions with 12V power. Then you will match the functions versus the colors. Because you have an extra...
