Optronics ST16 Series Combination Tail Light Dimensions

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 circuit board is sealed, which means that water will not 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 Rectangular Submersible Trailer Tail Light Installation

Today we're going to show you the Optronics trailer light, part number ST16RB. A few things to know about this trailer light is that it's designed for over 80-inch wide trailers, and it's also submersible. This particular light is for the right-hand side. This is also available in the left-hand version as Part #ST17RB. All right, this is our trailer light here. This is what you get with your part number, get the light, the three wires out the back, incredible piece of hardware to install. First off, a hardware, this slide needs to track right here.

Now, our wiring. Our white wire to the ring terminal is the ground. This green wire is going to be for our turn signal and ground for our running light circuit. Now, this light has all the basic functions needed for a backup trailer. The first part of our install is to see which tracks need using that light. There are two existing holes here, on our bracket for light.

It looks like they line up with these two slots. Let's go ahead and install the hardware. Just going to route our wires, in this case, the wires go off the side, swivel, and put them in the tracks that are provided for it. They simply press into place. The ring terminal is going to be trapped by the light from this side, so I'm actually going to take it and re-route it and go out the bottom. We'll go ahead and connect our wires first, then put it in place.

Now, the buck connectors we're using do not come with the light, so you can use your favorite attachments at this point. It's going to be color for color. Now since these are heat treating connector, we'll go ahead and apply heat and seal them up. We'll go ahead and take our wires, push them back into the frame as far as it can go. At the same time, we'll put our light in position.

Make sure our brown wire is coming out the opening at the bottom. Then we'll set our hardware back in the studs. Sometimes, you run into a situation where existing holes on a bracket are way too big for the volts that come with the light. An easy fix is just go ahead and add some flat washers to it, then we'll install the new nuts. Don't have to crush it, just make sure it's nice and secure. You'll find the location for our ground wire here. It's hollow behind the light a little bit, so you could probably run a very small self-tapping screw in there and it'll work just fine. Now, you can use this loop on the studs here for ground as well. Since there's a major difference between the hole size and the bolt, this is why I went directly to the frame. Let's go ahead and apply power to the light and try it out. First off, we'll do a running light circuit. Now we'll go ahead and check your brake light. That'll be the same thing as a right turn signal. With that, they'll finish it for our Optronics rectangular submersible trailer light, part number ST16RB. .

Good prices, quick shipping and excellent customer service makes me always check etrailer first when I require parts for my boat trailer. I have bought several items from etrailer and have always been completely satisfied. 202652

Last year I had a teenager learning how to back up with a trailer. This is how I came to need one replacement light. etrailer had a matching replacement light at a good price, and it arrived quickly and well packaged. That light is now starting its second season and is working well. I appreciated the wealth of information that is available on the website, and I found those resources very helpful. This year I have another teenager who needs to learn about trailers, so when the inevitable happens, I'll be back to etrailer! 388945

Finally got my order for the tail light working with Steph. There had been some sort of ordering mix up at the time of paying thru P ay Pal. I thought that the order was just VERY slow, Steph tracked it down, and the order was never finalized - ?? She then helped me reorder - paid $2.99 for lowest shipping on 6/20, got the tail light on 6/25 (in northern Illinois) - wonder how fast the expensive delivery would have been!! Thanks the Steph for all her help!!! By the way, the light looks perfect, just like the original on the trailer from the dealer. 663699

I had to replace my boat trailer lights on my 1995 Sea Ray boat trailer. These were the perfect replacement lights for the matching of the existing ones. The mounting holes lined up perfect, no drilling required, just remove the old and install the new. It took more time to connect the wires on each side than to mount the new lights. etrailer had these to me in three days, and there were exactly as described and many choices to pick from. I don't use the boat all that much, If it were newer and I used the boat more I would have went with the LED model. Again and as usual etrailer was top shelf on the shipping and the price!! Thanks folks, I'll be back again. 543470

The first tail light I received was broken in shipping, which does not reflect on the quality of the unit. etrailer.com sent a replacement promptly, so I was pleased about that. One problem I had was the mounting slot spacing is 1/4" different from the original lights I had, even though they both use the same lenses. I guess there is no industry standard for mounting holes on these. I had to re-drill the mounting holes in my bracket to make them fit. 305019

  • Based on your picture it looks like you are in need of some replacement lights and a bracket. It looks like you will need amber light # A91AB, red light # A91RB, and bracket # A91CB. And if you need the single wire (since the lights will ground through the bracket and mounting hardware) use # A91LW.

  • Most submersible tail light assemblies are constructed so that the bulbs are not accessible, although some feature lenses that are held on by screws with a gasket to keep the water out, like the Optronics lamp you referenced. If the bulb is indeed burned out, you will have to replace the lamp assembly. Before replacing the lamp assemblies, I would recommend confirming that the bulb is actually bad by using a circuit tester like part # 40376 on the wiring behind the tail lamps. It is...

  • How to Replace Bulb In Wesbar 8 inch by 3 inch Submersible Taillight
  • To replace the marker light bulb on the # ST16RB lamp, first remove the 4 phillips screws holding the lens to the lamp housing. Remove the lens. Then, remove the 4 screws holding the clear plastic cover over the bulb assembly. You would then grab the marker bulb and pull it out of the assembly and replace it with # A194B.

  • Does Ground of Trailer Taillight # ST16RB Need to be Waterproof

  • Tail Lights and Side Marker Lights Malfunctioning on Boat Trailer
  • The first thing to do would be to determine if the wiring issue exists on the trailer, or with the tow vehicle. Use a circuit tester, like part # 40376 and test the socket on your trailer connector that carries the signal for the running light circuit.

Check the connector on the trailer, and ensure...

  • What are the Dimensions of Wesbar Trailer Tail Light 106410
  • I went out to the warehouse and pulled a Wesbar trailer tail light # 106410 to measure it. It is 8 inches across, 2-3/4 inches deep, and 3 inches tall so it is very close to the dimensions of your old tail light. This light has mounting slots in the back that are 2 inches apart on center and the mounting hardware is included. The matching right hand side light is # 106411. Optronics lights # ST16RB and # ST17RB do match the dimensions you need.

  • Difference Between the Wesbar Ligths part numbers # 106410 and # ST16RB
  • The only real difference between the part # 106410 and the # ST16RB is that the # ST16RB comes with blunt cut wires and the # 106410 comes with quick connector that allows for easier wiring to a trailer as long as it has the same style of connector. The replacement lens kit part # 053522033360 will also fit either light.
