Excellent fit, high quality, and already dielectric greased!

by: 08/10/2022

packaging of taillights where loose causing them to get scuffed and scratched during shipping, quality and visibility of lights are excellent and pigtails really good, if lights would be individually packaged and taken better care of i would give 5 stars


Great product would buy again also highly recommend buying from e trailer fast shipping got what I ordered in 2 days


Plug is very durable and easy to use.
for working combined spaces


I recently purchased all new LED lights for a 28 year old Ranger Boat trailer I own. I had to add a 5th blue wire for the back up lights along with a new 5 wire plug. Everything came from etrailer and was an amazing, easy conversion from the old to the new. My new tail lights are amazing with the built in back up lights! Nothing but compliments from people who have seen them.
Your company was a pleasure to work with. You have a customer for life! Thank You!


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.


I was able to replace my existing lights with these that include the back-up light feature. Exact fit and work better than expected. Now I can see behind my 5th wheel when backing up the rig. The light harness along with the light fixture more than met all my expectations.


Fit perfectly


Worked great! Need it to install GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes - Oval - Clear Lens - BUL111CB


Product worked exactly as described... made for an easy conversion of my original LED tail lights to upgraded models that feature integrated backup lights.


These were a great option for the limited space available on my trailer. I find myself pulling my trailer at night frequently, and I'm not sure how I made it so long without reverse lights.


Great, Good quality, plenty of wire to work with.


I am greatly impressed with the quality and durability of this connector. It's sturdiness has already been tested and it passed beyond its oem predecessor!!

Its still attached to the trailer thus making it great product. The oem part failed which is why I needed a new one.
Jon C - 07/20/2017


Excellent service and attention to detail. I would highly recommend purchasing from etrailer. Prices are great and they have a wide selection of information that helps with the purchase decision. Very impressed.


Had to buy these when adding reverse lights to back of utility trailer. They work well in the led lights.
Easy to install and of good quality. No complaints.


Good plug. Have bought several. ships same day and they are great people to do business with.


while shipping was on the slow side the item Ipurchased was exactly the right fit and was of excellent quality at a great price.I highly recommend etrailer if shipping time is not an issue,their prices are good and the parts are of good quality.


They are the best


All is well and the product looks like it will work well.


Simple part. Fit the optronics lights that we have well.


I suggest using part of a pool noodle to ensure the connection stays tight, in the enclosier.
I used this in pole lights on a boat and they did rattle free , before I used the noodle mod.


I made this purchase for my son's boat trailer. I ordered on the Monday before Thanksgiving and it arrived the day before. Everything arrived as expected and well packed.


Right angle plug was a perfect fit. Arrived when it was scheduled. Great follow up customer service. I'll do business again with etrailer!


It's the correct pigtail for the lights they sell, what more can be said?


plugs were a snug fit. An I like the right angle easier to install into new bumper. so i rate this product a five

  • What Two Pigtails do I Need for my Fusion LED Trailer Tail Light Part # STL211RB
    For the Fusion LED Trailer Tail Light - Stop, Tail, Turn, Backup part # STL211RB you will use the Right Angle 3-Wire Pigtail for Optronics Trailer Lights part # A47PB for the three wire which will carry your running lights, turn/brake signal lights and your ground and the Right Angle 2-Wire Pigtail part # A49PB for the reverse light. I have linked a video for you on the installation process so you can see how they will work together.

  • 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.

  • Are Wiring Plug-Ins Needed for Optronics Trailer Tail Light # STL211RB
    Yes, wiring pigtails will be needed in order to install the Optronics Trailer Tail Light, # STL211RB. For straight pigtails you will need the 3-wire, # A45PB, and 2-wire, # A45CB. For right angle pigtails you will need the 3-wire, # A47PB, and 2-wire, # A49PB.

  • How Does Backup Light of Fusion LED Trailer Tail Light Work
    In order to utilize the backup light function of the Fusion LED Trailer Tail Light # STL211RB you will need to plug in a 2-Wire Pigtail, either part # A45CB or # A49PB for a right angle pigtail. You can see from the accompanying photo of the rear of this light that it has connections for both a 2-wire and 3-wire plug. This would need to be used along with the 3-Wire Pigtail # A45PB or # A47PB (right angle) which gives the light its tail light functions. I looked up your order from the...

  • 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.

  • Mounting Bracket and Wire for a Optronics Clearance Light # AL90AS
    For a mounting bracket you will need the Optronics Bracket for A91 Series Lights # A91OB. This bracket is confirmed by Optronics to fit on the back of your AL90AS light. This bracket comes with a gasket which creates a weather-tight seal. For a wire, I recommend the Right Angle 2-Wire Pigtail for Optronics Lights # A49PB. This Wire is convenient as the right angle allows the wires to run down from the light instead of straight out the back. The red wire splices right into your trailer...

  • Suitability of Optronics LED Trailer Back-Up Lamp # BUL11CBX for a Boat Trailer
    They certainly can. The Optronics # BUL11CBX is completely sealed and waterproof. They'd be perfect for a boat trailer. You'd also need either a right angle pigtail, part # A49PB or a straight pigtail, part # A45CB. Also keep in mind that although the lamps are waterproof, your trailer wiring might have junction points that aren't. This is why I recommend you unplug the boat trailer before backing into the water.

  • Wiring Plug Recommendation for the 6-1/2 inch Oval Light part # BU70CB
    I checked with Optronics and they recommend the part # A45CB and part # A49PB for plugs to fit the 6-1/2 inch Oval Light part # BU70CB that you referenced. It could be that your # A45CB just isn't orientated correctly so that it installs correctly, or that you are trying to install the plug into the wrong pins.

  • How to Mount Optronics LED Backup Light # BUL23CB on a Trailer
    The Optronics backup light # BUL23CB, is a flush mount light. You would drill a hole 4-5/16 inches in diameter in the surface you wanted to mount the light to. You would then wire in the pig tail harness, # A49PB, to the trailer wiring. Then mount the light in the grommet, # A45GB, attach the wiring to the light and push it into the hole.

  • Brightest LED Backup Lights Available That Fit Oval Hole On Trailer
    The GloLight LED Backup Light for Truck or Trailer # BUL111CB that you mentioned is going to be your best option if you are looking for the brightest backup lights in the oval recessed mount style. This product does not offer specs for lumens; I did contact Optronics to verify. They did, however, confirm with me that this LED backup light is going to be the brightest one available. It has 22 diodes, which is more than any other light in this configuration/style. This is DOT compliant. The...

  • How Much Amperage Is Required to Add Reverse Lights to Trailer
    If the tow vehicle has a trailer reverse light circuit separate for trailer wiring then you'd be limited by the amperage rating of the fuse that protects it. If you are tapping into the reverse light circuit of your vehicle for the light then it comes down to the amperage rating of the fuse that protects the circuit as well as the amperage rating of the lights and how many amps are left over between those two numbers. Now with that all said if you went with an LED reverse light like the...

  • 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.

  • Recommended Clearance Light And Grommet For Older Snowmobile Trailer Rebuild
    The clearance light I recommend for your snowmobile trailer is part # MCL57RB. This is a 3 diode 2-1/2 inch round light. It does require a rubber grommet for installation. The grommet to use for installing this light I recommend is part # A57GB. You may need to take a small round file and open the mounting hole you said measured about 2-5/8 inches but this should work well for your trailer. To connect the light to your trailer wiring I recommend using the Two Wire Pigtail, part # A46PB....

  • Outside Diameter of 2 Inch Round Grommet
    The outside diameter of the 2" Round Grommet # A54GB you referenced is 2-3/4". This grommet is used with 2" round lights such as the GloLight LED # MCL155RB (Red) or GloLight LED # MCL155AB (Amber). You will also need a 2-wire pigtail to complete the installation of these lights; either # A46PB for a 6" lead or # A49PB for a 10" lead. I have added links to video reviews of these parts for you to check out.

  • Number of Prongs on Optronics ONE LED Backup Light
    The Optronics ONE LED Backup Light # BUL002CB does have three prongs on the back however only two are used. The 2-wire pigtail to use with the light is # A45CB or if you want a right angle plug use # A49PB. To install the light the PVC grommet is # A70GB.

  • Are Load Resistors Needed for Reverse LED Trailer Lights
    You will not need load resistors to install the Optronics LED Backup Light for Truck or Trailer # BUL35CB; load resistors are not needed for reverse lights like these. The only thing you will need are Grommet # A33GB and a 2-wire pigtail, either part # A45CB or the right-angle pigtail, part # A49PB. I have added links for video reviews for you to check out as well.

  • Recommended Brightest Interior Utility Light Replacement
    The Miro-Flex LED Utility Light - 12 Diodes - Round - Clear Lens # OPT57FR would be a good choice for an interior replacement light for your trailer. Although the number of diodes does not necessarily indicate brightness, this has the most of any round utility light we have. The light measures 4-5/16" in diameter and is 2-3/8" deep. If you want to mount it flush you will also need the Rubber Grommet # A45GB. From what I have found it looks like the Peterson has a single wire installation....

  • Submersible LED Trailer Light Recommendation to Provide Standard Functions and Back-up Lights
    In order to have the tail light functions that you requested, you would have to go with two separate lights. I recommend taking a look at the Wesbar Wrap Around Tail Lights. For the 8-function left hand side, part # 271595, and part # 271594 for the right hand side of your trailer. These lights will serve as a stop, turn, tail, rear clearance, rear reflex, side marker, side reflex and license plate illuminator on the driver's side light. Next you would need to add a back-up light like...

  • Recommended Miro-Flex Clearance Lights With Clear Lens For Trailer
    We do offer Miro-Flex lights with clear lens for your trailer, but none of the Miro-Flex lights we carry are round with clear lens. The lights I recommend with a clear lens are part # MCL-50CRK. These lights have 3 LED diodes and come with the plug and grommet needed to install. For a round 2 inch Miro-Flex light, we offer the amber light, part # MCL50AB and the red light, part # MCL50RB. To mount these lights you would need the rubber grommet, part # a54gb, and you would need either...

  • Availability of 6 Inch Long Oval Red and White Light Assemblies
    The closest options we have available to what you are looking for are the Red GloLight LED Trailer Light # STL111RB and the White GloLight LED # BUL111CB. Both light assemblies can be paired with the PVC Grommet # A70GB and feature a sonically sealed, waterproof housing and lens that is submersible. The red light assembly can be used with the 3-Wire Pigtail # A47PB and the white assembly will work perfectly with the 2-Wire Pigtail # A49PB. The light assemblies measure 6-1/2 inches long,...

  • Recommended Oval LED Lights and Brackets for Flat Bed
    For your flatbed setup, I recommend starting with the brackets # BK70BB. Then I recommend using the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # a70gb to hold the lights in the bracket. For the red led lights I recommend the Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 10 Diodes - Red Lens # STL72RB with wiring pigtail # A47PB. For the white led lights I recommend the LED Backup Light for Truck or Trailer - Submersible - 10 Diodes - Oval - Clear Lens - Qty...

  • Submersible Reverse Light Recommendation for Boat Tariler
    Best option we have would be the white utility light part # BUL602CB which is submersible and provides quite a bit of white light for visibility when backing up. Then to mount the light you'd need the mounting bracket part # BK70BB, the mounting grommet # A70GB, and then the pigtail part # A49PB.

  • LED Tail Light for Boat Trailer
    There are no white, oval LED tail lights we carry which have a curved face. We do carry the 22 diode GloLight LED Backup Light # BUL111CB which is submersible but you would need to make your own mounting spot as it is a recess mount that also requires Grommet # A70GB and 2-prong plug such as # A49PB.

  • Compatibility of Optronics Backup Lights, Grommet and Mounting Bracket
    I can confirm for you that each of the parts you referenced will fit and work together. The GloLight LED Backup Light # BUL111CB, PVC Grommet # A70GB, and Trailer Light Mounting Bracket # BK70BB are all compatible with one another. The only other part you would need is the 2-Wire Pigtail for Optronics Trailer Lights # A49PB. I've added links to video reviews of each of these parts for you to take a look at as well.
