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. 820984

  • 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.

  • 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,...

  • 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 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.

  • Recommended Three-Prong Wiring Plug For Optronics Sealed Round LED Trailer Light # STL43RB
    We do have the three-prong pigtail you can use with the Optronics Trailer Light # STL43RB. You will need part # A45PB. This has the three-prong plug with 10 inches of wire.

  • 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.

  • Do You Carry the Wire Pigtails and Grommets Needed to Install Optronics 4 Inch LED Light STL53AB
    The grommet for the Sealed 4 Inch LED Light you were looking at is part # A45GB. The outer diameter is 5-3/8 inches. It is designed to use used in a 4-1/2 inch cutout or hole. The 3 wire pigtail is either part # A47PB or part # A45PB depending on style needed.

  • 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.

  • 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.

  • Recommended Trailer Tail Lights for 4.25 Inch Opening
    The LED Trailer Tail Light # STL42RMB has screw mounting holes that are 4-1/4 inches on center. The smallest hole this light will fit is 4 inches. You will have difficulty mounting this light as your opening matches the mounting hole locations so you won't get proper hold. You may want to use the Rubber Grommet for 4" Round Trailer Tail Lights # A45GB along with the # STL55RB which won't use any screws to mount. You will also want the 3 wire pigtail # A45PB.

  • Cutout Dimensions Needed for Flush Mount Oval LED Trailer Lights
    The Optronics LED Trailer Tail light - Stop, Tail, Turn - Submersible - 10 Diodes - Red Lens # STL72RB will use the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB for mounting. With this combination the opening you need to cut is a 6-11/16" long x 2-5/8" wide hole like you can find on the mounting bracket # BK70BB. You may want to get the bracket as a stencil to give you the perfect fit. You will also need the wiring pigtail # A45PB for each light. The kit you mentioned #...

  • 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...

  • Best LED Replacement Light for a Truck-Lite Model 60
    We have had some other customers inquire about replacing Truck-Lite model 60 lights before and have found that the Optronics Trailer Tail Light # STL72RB is a great LED replacement. For a grommet use part # A70GB and for a pigtail use part # A45PB. This tail light has the following dimensions 6-7/16" L x 2-5/16" W x 1-3/4" D which you can see in the attached photo. I have also linked an installation video for you to reference.

  • 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.

  • 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,...

  • Replacement LED Tail Light for Trucklite Model 60
    Based on the dimensions for the Truck Lite Model 60 that you have it matches the Optronics 10-LED Trailer Tail Light # STL72RB so this light will work as a replacement for you. The 48-LED version # STL70RB that you referenced is the same size and will work too. For a grommet you would need the part # A70GB and then for a harness part # A45PB.

  • 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...

  • 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...

  • What is the Candela Output of Optronics 6-1/2 Inch Incandescent and LED Tail Lights?
    I do recommend you move to LED lights as they are going to last much longer than the incandescent lights on your horse trailer. As far as light output, Optronics generally measures their lights in candelas instead of lumens though at a distance of 1 foot candela is equal to lumens so you should have a good idea of how bright the lights are. I contacted Optronics and the representative was able to give me the candelas of each of the lights you were asking about. The incandescent # BU70CB...

  • 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 Karavan Snowmobile Trailer
    We offer oval trailer tail lights in both standard bulb and high-efficiency LED types that you can see on the linked page. The lights shown are all recessed-mount types and most of them have dimensions of 6-1/2 x 2-inches. I also linked our main page for trailer tail lights of all shapes. LEDs are popular because they need less power, offer brighter light output and do not require periodic bulb replacement. For instance, part # STL72RB is a waterproof LED stop/turn/tail light assembly...

  • 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.

  • Good Looking LED Taillight Kit for Truck with Flat Bed
    For what you are looking for I think our best looking option is the Light Guide LED Trailer Tail Light # STL602RB which is an LED taillight setup with a unique design that would look great on your flat bed setup. It's not smoked, but we had a chance to install it on a flat bed like yours and we found it worked and looked great. See install video. For a grommet to install it you'd want the # 40-06-020 and then for a wiring harness # A45PB.

  • GloLight LED Tail Light Compatibility with 2018 Coachmen Clipper ST108
    The GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 22 Diodes - Oval - Red Lens # STL178RFPB is most likely a fit for your 2018 Coachmen Clipper ST108. The best way to confirm fit is to check the mounting hole locations. The mounting holes are 7 inches on center and 2-11/16 inches on center. I've attached a photo to assist. Then you can use the Snap-on Reflector Ring for STL78RB Series LED Lights - Red # A78RXB, the chrome ring # A78CB, or the stainless steel trim...

  • Comparing Optronics # ST40RB and Optronics # STL003RFLB Trailer Lights
    Aside from the Optronics # ST40RB having an incandescent bulb and the Optronics # STL003RFLB being LED the only other big difference is that the first part grounds through the mounting hardware while the LED version grounds through a wire. This is why one unit has 2 wires and the other has 3. We have 2 pigtail options for the LED verison for you to use. Part # A45PB has the wires coming straight out of the plug while part # A47PB has a right angle for tight spacing where your lights...

  • Trailer Stop, Turn, Tail Light With Clear Lens
    I may have an option for you but there is not a tail light available with a clear lens or housing that is exactly the same as the Optronics LED Trailer Tail light part # STL72RB. The department of transportation does require brake lights to be red so it is uncommon for the lens to be clear on the stop, tail and turn lights.There is the Optronics LED Trailer Turn Signal and Parking Light part # STL72CAB with clear lens but it lights up amber for turn signal and parking.

  • Wire Functions for Trailer Tail Light - Stop, Tail, Turn STL72RB
    The first thing to do is figure out the functions of the wires on your Kubota. Using a circuit tester such as # 40376 or a meter if you have one you can test each wire while someone operates the various light functions. On light # STL72RB you would use pigtail # A45PB. On it the white wire is ground, the black wire is for tail/running lights, and the red wire is for combined turn signal and brake lights. Once you know the functions of the wires on your lights you can match them up to...
