• LED Replacement for WESBAR 203561 Light
  Yes, the Optronics Trailer Light, # STL70RB, will replace the Wesbar 203561 to upgrade to LED lights. You will want to check the factory grommet when you remove the light, if the factory grommet is in good condition you can use it with the LED upgrade. If the factory grommet is worn or shows any signs of damage, now is the time to replace it. You would use the Optronics Rubber Grommet, # A70GB. Same thing on the 3-prong plug connector, check it also to make sure it is in good condition....

• Replacement Trailer Light for a Wesbar 203561
  Yes! I am happy to report that Optronics trailer light # STL70RB can be used as a direct replacement for Wesbar light 203561. The Optronics light requires a pigtail harness, # A45PB, since it doesn't have wires in the back. I have included a link to a video review of this light for you.

• Replacement LED Trailer Lights for Kaper KII Lights for a 2009 Haulmark Trailer
  The lights that you have referenced, # STL70RB, do have the same measurements as the Kaper lights you have with the exception that they do not stick out as far from the trailer. As for the clearance lights I do not have one that is an exact match for the dimensions you have given. A close match is # MCL65AB. It measures 3-15/16 inches long and 1-1/4 inches wide. To mount it you would need a bracket like # A65PB or # A67CB.

• How to Replace Optronics Taillight Part # STL70RB on a Cargo Trailer
  If your trailer has flush mount lights like the Optronics Sealed Oval LED Tail Light, # STL70RB, then I have two ways for you to remove your old taillights from your Haulmark Cargo Trailer. These taillights are sealed, therefore, you need to change the entire assembly, not just the bulbs inside. If you have access to the backside of the light from the inside of your cargo trailer and your lights are hardwired, then you need to cut the wires close to the old taillight and gently push it...

• LED Replacement Tail Lights for Incandescent Type on 2013 Calico Horse Trailer
  I was able to find images of your Calico horse trailer's Kaper-brand oval tail lights. These appear to be grommet mount types that use a rubberized ring for installation, similar to the LED light you referenced, Optronics # STL70RB.

• Replacement License Plate Light For 2009 Haulmark 7x12 Low Hauler Trailer
  I did some research on your 2009 Haulmark Low Hauler trailer. I was able to see several different styles of license plate lights and holders on trailers. I have attached a link to our product page for license plate lights. Some have the license plate holder attached to the assembly and some are just the lights that are mounted to light the license plate. There are different opinions about mixing LED and incandescent lights on the same circuit. We have had customers that wire them in the...

• How Do I Replace The Bulb On My Rola Swinging Enclosed Cargo Carrier
  The lights in the Rola Swinging Enclosed Cargo Carrier for 2" Trailer Hitch, part # 59109, are sealed. You cannot replace the bulbs, but you can replace the lights. It would require prying the light fixture from the grommet, disconnecting the plug from that light fixture, and connect it to the new light fixture. Once that is done you can install the new grommet, if needed, and the new light fixture. You can go with a regular incandescent light fixture, such as the Optronics Trailer Tail...

• Is Optronics 48 LED Light # STL70RB Brighter Than Optronics 10 Super LED Light # STL72RB
  I spoke with my contact at Optronics and they said the trailer lights are measured in candela output. Candela output is the luminous intensity of the light, or candle power. For comparison they said the candela output on a 100 watt incandescent light bulb in your home is 100 cd. They said the Optronics Sealed, 6-1/2 Inch Oval LED Trailer Light, 10 Super LEDs, part # STL72RB, uses 10 Super LEDs and has a candela output of 12 cd on the tail lights and 221 cd on the stop and turn lights.

• Need Replacements for Kaper KII LED Tail Lights Installed in Tailgate
  In cases when tail lights are installed within a tailgate it may sometimes be that the hinge mechanism in the tailgate does not provide a good enough electrical ground connection; this can cause some lighting functions to not operate properly. If this is the case then routing a separate jumper ground wire from the light fixture ground wire to the vehicle/trailer frame can provide a better ground which will allow more current to pass. It is also possible that the wiring is carrying the...

• How to Replace the Tail Lights in the Rola Tilting Enclosed Cargo Carrier Model # 59110
  The Tail Light on the Rola Tilting Enclosed Cargo Carrier, item # 59110, does not have a replaceable bulb. The taillights are sealed to prevent water from entering the housing and causing the bulb to blow out prematurely. You will need the Sealed, 6-1/2 inch Oval Trailer Stop, Turn and Tail Light, 3-Function, item # ST70RB. To replace the light you will need to pry the light fixture from the grommet that is installed in the carriers housing attach the plug to the new light and install...

• Does Bargman 47-84-527 LED Trailer Taillight Have a Rubber Base
  The base or bezel used by the Bargman # 47-84-527 Double LED tailllight is constructed of hard plastic, like the other rectangular lamps of this type. If you click the provided links, you can see a product demonstration and an install video. 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.

• Flush Mounted LED Lights for Flatbed Trailer
  Thank you for the photos; based on what you showed, you would want oval LED lights that are in the 6-1/2" x 2" range, though you would need exact dimensions to ensure the right fit. For example, # STL72RB is a red oval light that measures 6-7/16" x 2-5/16" x 1-3/4" deep while # STL70RB is another red oval light but with dimensions of 6-1/2" x 2-1/4" x 1-1/8" deep. The same will apply for your white oval lights, such as the 6-1/2" L x 2-1/8" W x 1" # BUL72CB. The other lights look to be...

• After Installing LED Trailer Tail and Clearance Lights Only Turn Signals Work
  It is not likely that the clearance lights, # MCL95RB, are the issue since they ground through the mounting hardware and only have one power wire that goes to the running light circuit. Still it is worth checking to make sure that the grounds are attached to clean and corrosion free bare metal surfaces. On the taillights, # STL70RB, the red wire is for brake lights and turn signal, black is for running lights. And white is the ground. You can't always go by color; you have to go by function....

• What is the Replacement Light for the Princess PowerFist 8186587
  I have a solution for you but the Princess PowerFist replacement light 8186587 is a sealed unit in which there is no way to replace the bulb. Instead use the Optronics Trailer Tail Light - Stop, Turn, Tail - Submersible part # ST70RB. This light is the same size and design. It uses the same connector as the other so you won't have to rewire anything. It simply plugs in then gets pressed into the grommet that holds it.
