Optronics STL2 Series LED Combination Tail Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.


To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

Video Transcript for Optronics Square LED Trailer Tail Light Installation

Speaker 1: Today you're going to be getting a look at the Optronics over eight inch wide square LED trailer tail lights. You can pick up the driver's side with part number STL3RB or you can pick up the passenger's side with part number STL2RB.These multi-function tail lights are designed for trailers over 80 inches wide. It features eight functions, rear and side reflectors. You have your stoplights, tail lights, your license plate light, your turn signal, side marker light and rear clearance light.The passenger side has all the same functions without the license plate light. The driver's side features 23 LEDs, the passenger's side has 18 LEDs, again because there is no license plate light.The attachment of the rear clearance light eliminates the need for a separate light to meet DOT requirements. They're made with an all weather molded plastic housing and a durable lens to protect against corrosion.

Compared to incandescent tail lights, LEDs are more efficient, they last longer and there's no bulbs to replace. These are going to be a nice upgrade or replacement for your trailer. Now we'll show you how easy they are to install.I've already gone ahead and removed my old lights. You can do so by removing the nuts on the back side of the light, and snipping the wires. Now it's not a bad idea to make sure the area is clean of any dirt or debris.

We can go ahead and get started by taking some wire strippers and stripping back our wire about a quarter to three-eighths of an inch.Our lights wires do come pre stripped. We're going to take just a little bit more off. Our ground wire comes pre-installed with a ring terminal, so we're all set there. Now you can install your light before you connect your wiring.If your studs don't match up with the holes on your trailer, you may have to drill. I'm going to take my license plate bracket, because we're on the driver's side, take my flat washers, line it up with the holes and then push it through.

Then I'll take the flange nuts and put them on the other side. I'll get one started and hand tightened, and then we can repeat the same process with the other stud.Once you have both hand tightened, you can take a seven-sixteenths wrench and tighten them down the rest of the way. But we sure not to over tighten, just get it nice and snug on both sides.Now we can start connecting our wires. Since we're working on the outside of the trailer, we're going to be using some heat shrink butt connectors. They're available on our website at etrailer.com.

I'm going to start with my yellow wire here, and I'm going to clean up the wire by twisting it a little bit. Then I'll take the heat shrink butt connector and put it in place. Want to make sure that the wire is not visible and crimp it together. Once it's crimped, it's a good idea to make sure that it's not going to come back out, then we can repeat the same process with our brown wire.Now we're going to connect our wires together, color for color. Brown is our running lights, our yellow is our turn signal. Connect and then crimp. Once we've got them all connected, then we can take our heat gun and shrink them down. If you need one, this also is available on our website, etrailer.com. By shrinking these down, it's going to prevent road grime, dirt, debris and moisture from getting inside.Now I'm just going to take some electrical tape and put it on my wires to help further clean up my look. Once everything's all wrapped up, just going to tuck it back behind here.Now the only thing left to do is to connect our ground wire. You'll need a self tapping screw. We're just going to go right through the middle here. Now we can repeat the same process with our passenger side. With both lights installed, now let's test them out. That's our tail lights, our brake light, on the left hand side, our brake on the right hand side, our left turn signal and our right turn signal. And here's our license plate light.And now you've had a look at the Optronics over eight inch wide square LED trailer tail lights.

Product was exactly as I expected it would be. I pull a trailer for lawnmowers a lot and need to have lights that work properly. I am glad I found etrailer and could order what I needed. Carolyn Fulk 637032

Having broken my trailer's taillight pulling it out of a tight squeeze, I was happy to get the replacement from etrailer.com in just three days. When I installed it, at first only the parking light and running light worked. I called customer service and was surprised to have a real person answer as it was late afternoon on Saturday. She advised me to buff up the area on the trailer where the ground makes contact. I did and the light came on fine. Great customer service! 579971

Does the job very well. The side marker extends out more than I like, but I understand that this is a design that replaces rear and rear side markers on over 80" wide trailers. 409525

Just received and installed this light today. Replaced 7 year old lights on my utility trailer hoping to not have to mess with light bulbs anymore. The light works as it should, it's nice and bright, arrived in a reasonable time frame, was packaged well, and hopefully will last. I have ordered many items from etrailer and have never had a problem. 387510

Great light. Arrived quickly and performs flawlessly. I've had other trailer lights that the bulbs would short out or the bulbs would bounce loose with the vibrations of the trailer, but this one. It is still burning strong after a year of road use. It's also very bright, easy to see in daylight. 355322


Comments

3/18/18 Light still works great. My trailer is in constant use hauling tractors and UTVs back and forth. Even with all that road use and some off road use the light still works properly. What more could you ask for than a product that does what it is supposed to do. Thanks etrailer

All ordered items worked great. Love the LED tail lights. Didn't have any problems fixing the trailer thanks to the many technical articles I found on etrailer. Not sure what happened with UPS shipping since I got notified that the parts had shipped on Saturday but didn't get them till Wednesday evening (paid extra for 3 day shipping), but definitely recommend ordering from etrailer. 341400

Awesome product from an awesome store. Product arrived just as described. Packing was great and looks just like I expected them to from the etrailer.com web site. Will get them installed and reviewed further. Hopefully this time, some bonehead won't back into my trailer in the parking lot of the boat ramp. Thanks etrailer for the great service. 216937

Had a damaged light on my trailer and decided to go with LED this time, so I replaced both sides. Very easy to install. Wires were color coded and matched my harness. Looks and works great. I was not able to find the LED in 80" plus size in local store for some reason. Only could find the 80 and under model. etrailer came through for me. Would buy from them again. 214564

I received two lights for my birthday last September. I installed them on my trailer in October. The lights looked great, very bright. However, one of the lights had the side marker light go out. Since you can not replace the bulb I have purchased this replacement and will see if I have better luck with it. I will let you know. 181651

Replaced the old taillights with incandescent bulbs on our old cargo trailer as they just weren't bright enough to see easily in bright daylight. These LED taillights fixed that problem - they are easily seen at any time of day or night! And , as always, etrailer was great to do business with - I especially like how well they keep me posted on my order status. 79313

I just installed and tested them. They installed quite easily. They are nice looking and bright. They seem to be well built. We'll see how these are after a couple years. My last set were also L.E.D. type (but not this brand). I thought, barring any accidents, they would last many years. They didn't. They did last longer that the incandescent type though. Vibration seems to be the biggest enemy for trailer tail lights. 51369

Ask the Experts about this Optronics Trailer Lights

Do you have a question about this Trailer Light?


  • Tow Dolly Replacement Lights
  • For your old car dolly, you may be interested in the Replacement Driver's Side Fender for Roadmaster RM3477 Tow Dolly with Electric Brakes - Metal # RM-922004 and # RM-922005. For similar lights you can use the Peterson Square Trailer Tail Light, 7-Function, Left Hand # 432400 and # 432200. For light from the sides instead of reflectors, you can use the Over 80" Wide, Square LED Trailer Tail Light, 7-Function, 18 Diode, Right Hand # STL2RB and left hand # STL3RB.

  • Options to Replace Square Tail Lights with LED lights for Over 80 Inch and Under 80 Inch Trailers
  • If your trailer came with the square Peterson lights then you can use the Submersible LED Trailer Light Kit, # TLL9RK. The Over 80 designation that you see is a federal guideline for trailers that are over 80 inches wide, and extra lighting is required for these trailers. You should check federal and state lighting guidelines if you are not sure that your trailer has the correct lighting installed on it. At this time we do not have an LED version of the Over 80 inch square tail light...

  • Square LED Trailer Lights and 5-Way Wiring Harness for a Wesco Boat Trailer
  • Over or under 80 means 80 inches of width. There are certain lighting requirements if the trailer is more than 80 inches wide. Trailers that are less than 80 inches wide can still use lights that are indicated as over 80 inch. Since you need a 5-way wiring harness I recommend getting the lights separately, # STL8RB and # STL9RB, and then getting # A25W5B for the harness. This is a 5-Way wishbone harness. That means that the running light pin has 2 wires for running lights on each side...

  • Troubleshooting Installation of Optronics # STL2RB and # STL3RB
  • There are two possibilities that are outside the box of thinking, however, are very relevant to your lights not working and there are a couple of standard reasons why your lights may not be working. The first thought is the actual specs on your factory 7-way. It seems as if you have a lot of lights on your trailer, and although some of them are LED which use substantially less power, check the capacity of the connector and then add the usage up of the lights - you may be over capacity...

  • Recommended LED Trailer Lights to Replace Some Incandescent Trailer Lights on Large Trailer
  • You absolutely can mix LED and Incandescent lights on your trailer. For your PM444 replacements, I recommend the Optronics Over 80" Wide, Square LED Trailer Tail Light, 7-Function, 18 Diode, Right Hand # STL2RB and Left Hand # STL3RB. The LED lights will draw less power and will also get rid of the bulb replacement hassle you mentioned. In rare cases you may experience hyperflashing with LED lights. If this happens when you install these lights, you can simply add a load resistor...

  • Does the Replacement Tail Light Lens # AL8RB-1G Go to a Light with License Plate Function
  • The Replacement Tail Light Lens for STL2RB and STL3RB # AL8RB-1G is a replacement for both the Optronics Right Hand # STL2RB and Left Hand # STL3RB lights as is indicated by the title. The part # STL3RB does have the license plate light function built-in to it.

  • How Waterproof is the Over 80" Wide, Square LED Trailer Tail Light # STL2RB
  • The Over 80" Wide, Square LED Trailer Tail Light # STL2RB that you referenced is designed to be a submersible light. What that means is that once you got to the boat ramp you would want to disconnect your trailer wiring from your tow vehicle and then you could back your boat trailer into the water and the lights will be totally fine. The LEDs are sealed so that water would not get to them. This light would be exactly what you need. For the left hand side you would want part # STL3RB.
