• Rubber Grommet for Optronics LED Trailer Light
  Hi James; are you referring to the Optronics LED Trailer Light # STL43RB you were looking at? Are you using the Rubber Grommet for 4" Round Trailer Lights # A45GB or something else? The only other option we have is the Trailer Light Mounting Bracket for 4" Trailer Lights # BK45BB but that also requires the use of the grommet.

• Replacement Reverse Light for Ranger z521 Boat Trailer
  I have a solution that may work for you, but we do not currently have any 3" diameter submersible reverse lights. Have a look at the Optronics Backup Light # BU45CB which is a 4-1/4" diameter light that can be mounted to your trailer using mounting bracket # BK45BB. You will also need the 2 wire pigtail # A45CB to replace the wiring from your old lights and plugs into the back of this Optronics light. I've attached a photo that outlines the dimensions of the light to see if you can match...

• Recommendations For Adding Tail Lights To A Kuat NV 2.0 Bike Rack
  Though you will need to have a 4 Flat on your 2001 VW Eurovan, and for this I do recommend the Curt # C56175, adding lights to your Kuat NV 2.0 is definitely a good idea. I went through all our options for adding lights to a bike rack or cargo trailer, and the Curt Auxiliary LED Indicator Lights # C53201 will be the good option, but there is a potential issue. The base of the rack is not the same length on both sides and the arm the swings up and tightens down on the wheel will give you...

• Are there Replacement Tail Lights for a 1982 Scamp Trailer
  In order to determine which replacement lights will fit your 1982 Scamp trailer, you will need to find the manufacturer and model number of the light assembly. This could involve removal of the assembly. If you see numbers on the lens, those are not the correct numbers. If you cannot find any manufacturer/model number information, you will need to measure the diameter of your existing tail lights and any other dimension that you can. You will also need to determine how they mount to the...

• Can the 4 inch Rubber Grommet # A45GB be used in a 4-3/4 inch Mounting Location
  I do have a solution for you, since the hole that you are placing the grommet in is 4.75 inches, the grommet that you referenced, the Optronics # A45GB, might push through that mounting hole since the overall diameter is 5-3/8. Depending on your exact mounting location you might be able to use the # BK45BB to install on your light mounting location then use the 4 inch grommet # A45GB to hold a 4 inch light. I am not sure if this will work for your application but you might also be able...

• Replacement LED Trailer Tail Lights for a 2005 Gulfstream BT Cruiser
  Optronics trailer tail light # ST45RB is potentially a fit for your trailer if the existing lights are one of the following: Uni Bond # SE4000R Wesbar # 423541 Truck Lite # 40282R/40202R Grote # 52922 Peterson # 426R Bargman # 40-01-001 This information is likely on the light housing somewhere on your existing lights. The 2 knobs on the back are not an issue since this light would mount in a hole in the trailer or in mounting bracket # BK45BB both using grommet # A45GB. If you are not...

• How to Convert a 4-way into a 7-way for Backup Lights on a Boat Trailer
  There are three things that you will need to do to add reverse lights to your boat trailer. The first thing you will need to do is add a 7-way connection on your trailer. You can use the 7-way # HS381-9000 with the junction box, or you could go with the Pollack 7-way Connector # PK12706. The big difference between these two is that with the junction box you will make all of your wiring connections inside the junction box, but you need to keep the junction box in a safe place, so it doesn't...

• Installation Assistance With Mounting Hole Dimensions Optronics GLOLight LED Stop/Turn/Tail Light
  To install the Optronics GLOLight LED # STL101RMB you will also need grommet # A45GB. There are two mounting options for this LED light. The first one is using Optronics grommet # A45GB and mounting directly into your 1998 Jeep Wrangler. The other option is using the Optronics Mounting Bracket # BK45BB. If you decide to use the mounting bracket, you will still need the grommet as well. If you are mounting using the grommet only the grommet opening is 4-1/2 inches. When cutting this...

• How Does Trailer Light # ST45RB Mount into Mounting Bracket # BK45BB
  I went out to the warehouse and pulled Optronics Trailer Light, # ST45RB. First, you will need to place the Rubber Grommet, # A45GB, into the mounting bracket, # BK45BB. Next, you will need to press the light until it is seated all the way in the bracket. This last step actually takes some strength as the light is held in place by the grommet. I had to use some lubricate to get the light to seat all the way in the mounting bracket. Once in place, the light will not come out unless it is...

• Availability of 2 Inch Diameter 3-Function Taillight
  There is not a 3 function lamp available that has a 2 inch diameter. DOT regulations require that tail lamps meet certain size and visibility requirements. Clearance/marker lights can be smaller, but a 2 inch diameter taillight would not meet those requirements. There is a 4 inch diameter lamp, part # ST45RB. The lamp would typically mount in a grommet like part # A45GB set into an existing hole or using a bracket like # BK45BB.

• What Size are the Mounting Holes for the Trailer Light Mounting Bracket # BK45BB
  I went out to the warehouse and measured the mounting holes for the trailer light mounting bracket # BK45BB. The larger holes on top are 0.36 inches in diameter so 5/16 inch hardware would be the largest you could use. The smaller holes on the face of the bracket will accept up to 1/8 inch hardware. I also made a video showing the measurement of the large holes using digital calipers.

• Functions of Optronics 12 Diode Miro-Flex Tail Light # STL23RB
  The Optronics 12 Diode Miro-Flex LED Trailer Stop/Turn/Tail Light you referenced, part # STL23RB is a three function lamp. The # A47PB right angle pigtail, which is sold separately, has a white ground wire, a red wire that carries the brake and directional signal and a black wire that serves as the running light circuit. If the vehicle headlights were turned on, the lamp would be lit. Applying the brakes would make the lamp brighter. The lamp has several mounting options. It can be...

• Could Use a Trailer Light Mounting Bracket with a Sealed 4 Inch LED Stop Light
  Yes, I went out into our warehouse and pulled a Sealed, 4 inch Round LED Trailer Stop # STL42RB and a Trailer Light Mounting Bracket # BK45BB and found that they work together very well. All of the mounting holes from the # STL42RB line up with the # BK45BB. You would need bolts that have a diameter of no more than 3/16 of an inch to attach the light to the bracket. I attached a picture to the right that shows how these products would look if installed together. You might also be interested...

• Trailer Lights for 12 Volt and 24 Volt Systems on a 1994 Mercedes G Wagon and Honda CR-V
  Some trailer lights can be used on either a 12 volt or 24 volt system, but # STL16RB is not one of them. You could use # STL23R24B with harness # A47PB, grommet # A45GB, bracket # BK45BB for a 24/12 volt system and it would work with both vehicles.

• Trailer Light And Mounting Bracket Recommendation

We do have a mounting bracket, part # BK45BB, for a 4 inch light but the mounting holes are spaced 4 inches center-to-center. If you wished to drill the holes in the bracket to match the holes in the...

• Troubleshooting Light Not Working with the Cargo Carrier Light Kit # 52014
  If you installed the Cargo Carrier Light Kit # 52014, and all of the functions on one light are not working then it sounds like the problem is the light itself. If some of the functions worked on the light then I would say that you have a problem with the wiring somewhere. You can test the light by running a ground to the marked pin and then test the other 2 pins with a 12V power source. If you think that the wiring may be an issue then you can replace it with part # WHCETR1B. For a replacement...
