Video Transcript for Optronics Submersible Tail Lights Review

Speaker 1: Today we'll be having a look at the Optronics rectangular submersible trailer tail and license light for the left-hand side for over 80 inch trailers. Part number ST27RPG. Also available for the right hand side as part number ST26RPG. Here's what a light looks like installed. As you can see, even in the daylight, even with having an incandescent bulb, our brake lights are still very bright.This light is a great replacement solution for those of you that have boat trailers that ore over 80 inches wide. The reason this is a great replacement for boat trailers is that this is a submersible assembly so that when you back your trailer into the water to unload your boat, you don't have to worry about water getting inside here causing shorts or corrosion and your lights not working properly.What's great about this light, with its simple three wire system, is that not only will it function for our tail lights like we have right now, but it will also do our left hand turn signal and our brake lights as well as being able to cover our license plate with illumination due to its clear bottom.

As well as having our turn signals, our tail lights, our brake light and our license plate light, we also get a side marker here from the second mold that's in the system.With this assembly, we also have reflective capabilities on the back and again on the side. Now when it comes time to replace our bulbs inside the assembly in case they burn out, it's easy to do. We can easily remove the lens and replace the two bulbs inside. If we ever need to, this lens is replaceable in case of damage. Inside of our assembly, we have shock-proof sockets, which will help ensure long bulb life.Our light is easily mountable with the industry standard two inch centers.

Now for a few measurements to better assist you and see if this is going to fit your trailer at its widest point our light is 8-1/16" wide. At its tallest point it is 2-7/8" tall. As far as depth, at its deepest point it is 2-13/16" deep. What many of our customers like about this light assembly is that it is a direct replacement and works great with their older trailers.It matches what came on them from the factory perfectly. Now that we've gone over some features, we'll show you how to get it installed.

So to begin our install we first need to remove our old damaged light. So on the back side of our lamp assembly we're going to attach to our trailer. We'll find our two mounting studs and our 7/16th nuts, which secure into place. We'll remove the old nuts. Here with the nuts removed, we can now grab the light assembly and pull it away from our trailer.Okay, now we have these two wires right here.

We have the yellow and the brown. We're going to cut these away from the old light, and we can discard the light now. Our light has this quick disconnect plug here, however our trailer is currently not equipped with that. You can pick up a matching end on our website but what we're going to do, is we're going to cut off that plug and make our connections directly with some heat shrink butt connectors.So we'll strip off insulation from both ends, and we'll take some 14 to 16 gauge heat shrink butt connectors, which we have available on our website, and we'll crimp these into place. With those crimped on to our trailer end, we'll now match up our colors from our light. So the brown wire will go to the brown wire, and the yellow wire will go to the yellow. The brown wire is for our tail light and running light signal and the yellow wire, that is for our left brake light and left turn signal.And here's what it looks light with our wires crimped in place. Okay. We went ahead and used a heat gun to shrink down our butt connectors. You can pick up a heat gun on our website to do the same. You'll want to use a heat gun over a lighter or a source of open flame because a heat gun will provide indirect heat and won't damage the connector. Now this light does come with new studs and we'll use those. We'll match up where they we're on our old light assembly so we'll be using the one that will be closest to our trailer and then the one in the middle. Depending on your application, you may have to use this outer one.And the outer one, you can tell because it has the reflective side there and the inner side, well it's just black. And now we'll take our white wire which is our ground wire and we'll push it into the small gap right here and we'll place it over the stud there. We'll also make sure our other wires go through those gaps as well. These will just keep our wires from getting pinched by inaudible 00:05:30 those grooves. The yellow and the brown wire will go outside this gap here. So we'll place our wires inside our frame now and we'll work our light assemble over to its proper position.With our light now in place properly we'll take our new nuts and install them on the studs. Now we'll tighten them down. And that completes our look at the Optronics rectangular, submersible trailer tail and license light for over 80 inch trailers, part number ST27RPG.

I upgraded from 4-80 tires and wheels to 5-70 great product. Next replaced both broken tail lights nice fit no problem. Great staff to deal with Thank You Carol C , Noah

Just like the first day installed them.
Steve D - 08/29/2021


These products are well made and designed. The wiring harness is well designed for easy attachment and easy to figure out with wire color coding. I have 2 suggestions: more prominent display of Optronics trade name for easier replacement identification and shipping by USPS is not all that great. You are better off to use UPS or FedEx for much quicker delivery. UPS or FedEx take a day or two whereas UPSP takes a week or more.


The light emitted from it is very dull(low light).
I don’t know if I got a bad one or what, but I was expecting for it to at least as bright as the one I replaced.

Thank you for your review. If the light seems dull, I recommend to check that the ground connection is connected to a clean bare metal surface of the trailer. It sounds like you are having a classic ground issue.
-- Etrailer Expert Heather A - 06/07/2021


Perfect fit replacement and easy installation (1991 Escort trailer).
Only issue is that I installed LED center light panel that is 20 times brighter (and safer), so I'd consider LED replacements if I had to replace again. Not sure they would be such a simple replacement, though, since sizes differ slightly.


A complete tail-light kit replacement with the bulb, wow, this was the exact replacement for my pontoon trailer and at a great price! I received it fast, before Memorial Day weekend! Etrailer, you rock! I will definitely be a future customer!

Best regards, Steve


delivery was prompt. shipment packaging was very good to secure the purchase. I will install it in the next couple of weeks. not that they needed to, but checked the sealed light cover screws to be tight. this is what my failure was in the first place. I bought a new trailer and after one season this sealing cover failed. so far so good.


I recently purchased new trailer lights for my bass boat trailer. They came on time, very well packaged, and fit my trailer perfectly. I will consider them for all of my future trailer needs.


fast on time shipping. quality product. all questions answered professionally. will recomend and keep them in mind for future orders


Ordering was easy. Once submitted I realized that I had ordered the wrong side light. I called and the issue was handled right away with no problems. Excellent service, thank you.


What a great experience, the product was the right one and the price was awesome. The lady that helped me was very good and new what she was talking about.
I couldn't have had a better experience, thank you so much.

Still working great
