Video Transcript for Optronics Trailer Lights - Tail Lights - ST5RB Review

Today we're going to be reviewing part number ST5RB. This is the Optronics Square Submersible Trailer Tail Light with a License Plate Light for the left hand side of your trailer. The red square trailer light is going to serve eight functions for trailers more than 80" wide, such as your stop, turn, tail, rear clearance, rear reflex, side marker, side reflex and license plate illuminator. It's made from a corrosion resistant design. It's going to feature a replaceable lens as well as replaceable bulbs. It's going to feature shock proof sockets so it's going to guarantee long bulb life. It's got the stud mounts here on the back that are designed for the left side of the trailer.

If we take a measurement the distance between the two studs measuring center on center that's going to measure right on 2". The wiring design has a plug and go molded male plug for a water tight connection to the electrical harness. It also has this nice little pad back here so it is going to get a nice, tight connection. To go over the overall dimensions it's going to give us an overall length of 6-1/8". It's going to give us an overall width of 4-9/16" and an overall depth of about 2-7/8" not including the mounting studs on the back. Now if you need a light for the right hand side of your trailer you can find that with part number ST4RB.

That is going to be sold separately. We're going to go ahead and connect this to our external power source that way you can see what it looks like with power running to it. Now the brown wire is going to be for the tail light function so we'll need to connect that to the power source. The yellow one is going to be for our stop and turn signal so we'll get that connected as well. The unit is going to ground through the mounting stud so we'll go ahead and connect our ground wire to that mounting stud on the back. You can see here that's going to send out a nice, consistent signal. These are incandescent lights.

It's got the license plate illuminator here on the bottom. You can see that casting a signal down towards the bottom of the housing. Then when we hit our brakes you can see how everything is going to illuminate for a brighter, more consistent signal, also functioning as our turn signals. That's going to do it for today's review of part number ST5RB, this is the Optronics Square Submersible Trailer Tail Light with License Plate Illuminator for the left hand side of your trailer. .

I ordered these on Saturday, recieved them on Wednesday. Ordering was simple, cost was very competitive, and delivery was quick. For the purchasing part of my review I give etrailer an excellent rating. I have only had the product for a day...they have not even been installed yet, so I am not able to comment on the quality of the parts. They appear to be good stuff. 32840

Originally ordered a different brand of tail lights, but unfortunately one side was back ordered which would have delayed my shipment enough to put me pass my deadline to have my trailer ready. Rebecca at etrailer.com worked with me and suggested these Optronics lights as an alternate. She had them shipper out that day and they arrived quickly and in great shape. this vendor offers exceptionally good customer service and very reasonable pricing for all of your trailer needs. Will definitely be using them again for any of my trailer part needs. 313345

  • Why are Some Lights Listed as Over 80 Inches and Others Under 80 Inches
  • The reason there are trailer light kits listed for under 80 inches and over 80 inches is that there are different lighting regulations for vehicles that have widths that are larger than 80 inches in width than ones that are less than 80 inches wide. You will need to check with your local laws and regulations on trailer lighting also. Check out the LED Submersible Right Hand Light # STL8RB and the LED Submersible Left Hand Light # STL9RB. These are stud mounted, submersible, rectangle...

  • Trailer Wiring Recommendation for a 1991 Toyota Camry
  • Your best option would be to replace the old style of trailer connector you have on your 1991 Toyota Camry with a new wiring kit like part # C56175 that will give you a 4-way on your vehicle to match the 4-way on your trailer. Without knowing more about what kind of wiring you have on the Camry it would be very hard to figure out what you would need to do to make the kit work. I attached a review video for this wiring harness plus an FAQ on trailer wiring for you to check out as well.

  • Troubleshooting Malfunctioning Running Lights on Trailer
  • This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light but can show up any time. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean...

  • Left Handed, Submersible Trailer Light and License Plate Bracket Recommendation
  • What you will need is a Over 80 inch Wide, Square Submersible Trailer Tail Light with License Plate Light, 8-Function, Left, part # ST5RB. For a license plate bracket you will need a Trailer License Plate Mount Bracket, Angled, Rust Proof Polymer - Black, part # LP10SB. If you need a right handed light, you would want a Over 80 inch Wide, Square Submersible Trailer Tail Light, 7-Function, Right Hand, part # ST4RB. The reason I recommend a different Tail Light from the one you referenced...

  • Trailer Running Lights Work But No Brake Lights or Turn Signals
  • Optronics trailer tail light # ST5RB grounds through the mounting studs. If it is attached to aluminum or there is something in between the light and where it is mounted then that can interrupt the ground. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

  • Locating the Model Number for a Replacement Tail Light Lens
  • The lens will typically have a DOT number, but not a model number. A replacement lens is usually determined by the model number of the light itself. There should be a model number printed on the back of the light. If you have a square incandescent over 80 inch light like the Optronics Submersible Trailer Light, # ST5RB, that you referenced, then the Replacement Tail Light Lens, # A8RB, on your light. If not, then you can send me the model number of the light you have and I can make...

  • Ground on Truck Side Trailer Connector is Bad and Lights on Right Side of Trailer Not Working
  • If you are certain that the ground on the truck is the problem then what you can do is run a new ground from the back of the trailer connector directly to a clean, bare metal surface on the truck frame. Make sure the new location is free of corrosion, paint, and undercoating. If you continue to have issues then make sure the truck and trailer side connectors are both clean and free of corrosion inside where the wires attach and on the pins. The light grounds should also be attached...

  • Troubleshooting Snowmobile Trailer Wiring And Lights That Stopped Working After Hitting Street Curb
  • It sounds like you have physical damage somewhere in your system since you said this has happened since you hit the gutter in the street. You said the truck has power at the connector so we can feel sure that the problem lies with the trailer. You said you are getting power to the side wires on the trailer but you still have no lights. You will want to check the ground on each light to make sure they are attached securely to a clean bare metal surface. If you have a tilting trailer...

  • Trailer Taillight Replacement for a Blazer 6424 Taillight Assembly
  • Yes, the Optronics taillight part # ST4RB is basically the exact same thing as a Blazer 6424. For the matching light for the left hand side you would want # ST5RB.

  • Troubleshooting Trailer Wiring When One Side Of Trailer Has No Functioning Lights
  • It sounds like you are on the right track. Ground wire problems can cause a variety of issues such as the dim lights you mentioned to not working at all. You will want to inspect all the wiring for the lights and make sure there is no sign of corrosion or damage. Grounds should always be secured to a clean, bare metal surface. You will also want to check the trailer connector for signs of damage or corrosion to any of the pins. I have attached a helpful article that explains how to...

  • Replacement Lens for Tail Light
  • The code numbers and letters on a light lens are NOT usually the light's actual part number. Usually the actual manufacturer part number for the light appears on the base portion that is secured to the trailer and the lens has only DOT codes. Please refer to the photo of the item you referenced, part # ST5RB, which shows the part number on the back surface of the light base.

  • LED Replacement Trailer Taillights for Peterson 440-15R
  • The Peterson lights like the part # 432200 that you have are very standard in dimension. For an LED version of these all you'd need is the # STL009RB for the driver side and part # STL008RB for the passenger side. The mounting stud dimensions match too.
