Optronics # STL83RB


Peterson 844L Low Profile Combination LED 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.


Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

Video Transcript for Peterson LED Combination Tail Light Review and Installation

Hey guys, it's Randy here at etrailer.com. Today, we're going to be taking a look at a set of lights from Peterson. Now these are your standard square style light, the ones that are going to mount on the two inch centered studs. And these are designed for use really on any type of trailer but especially trailers over 80 inches. They're going to meet the standards for that and comply to that regulation. The thing I like about these lights is they're very unique looking.

The compact design here I think is really nice look, and we've also got limbs all the way down the side here at the part that sticks out there, which is part of that requirement. And then the full face here is really nice and flush. I think it's a very unique looking light. I think it has a very nice brightness and a very nice intensity to it.Those LEDs typically do always burn a lot brighter and a lot more clear in my mind than what an incandescent does, but these are also going to last much longer, looking at 50 times the life out of them. They also use a lot less energy.

We don't have that filament that we have to heat up. And that generally breaks when we hit rougher roads. Now, these are also a fully submersible light.The way they've designed the LEDs on the back of the lens, the side, and even on our license plate light down there, you can see real nice and bright is that they're fully sealed. So our wires do run in but they're going to go into an epoxy in there. Everything, as far as the LEDs go, the wiring and those wires, once they pass through, that's all sealed.

So this light can go underwater, come back out with zero issues. And in most cases I do recommend unplugging your lights when you do that but in this situation, I wouldn't even be worried about doing it without that.And something else I like is that we have the reflectorized lens here on the side and on the rear. So there's no need for additional reflectors or anything like that. Now the only real difference between this one, which is the one for the driver's side and it has our license plate light here on the bottom is that this doesn't exist on the passenger side. So be sure when you get your replacements, you get one of each, you have one for the right side.Now the housing itself back here really nice and strong.

Doesn't have a lot of flex or give to it, especially compared to some of the other ones that I've handled. And then the lens, I like the lens really nice and solid it's going to be an acrylic lens. So unless we run into it with something pretty heavy duty, I really don't think we're going to have to worry about cracking and discoloration and things like that, that we used to see really shouldn't be an issue either.So to begin our installation, of course, we're going to be using our studs that are on the two inch centers. And then what I like to do is just run my wire down. There's a couple of keepers right here and then there's a little gap for those to come out. So as we put it up against our mounting surface, they won't be pinch. Bring that down and on. I'm going to start with the outside stud first. I want to get my nut put on there to hold my light in place. On the other side, we're going to put our ground wire on the stud. You can see we've cleaned off an area there on the trailer for this to get a really good connection. Then we'll be using a seven sixteenths to tighten both of these down. Now this isn't something we need to over-tighten. We just want it to be snug.Now for the other two wires, we're going to have a red one and a black one. The red one needs to go to our stop and turn signal. That's generally on the left side going to be the yellow wire on the right side, generally a green wire. Then our black wire needs to go to our running light signal. Generally, that's going to be a brown wire. We're using heat shrink butt connectors here to make our connections, just twist your wire up really well. Slide that on and we'll crimp it down.Now, the reason I use heat shrinks on trailers, because they're always out in the elements and with just a standard butt connector, a lot of times moisture can get in there cause corrosion and it just seems to sometimes be a point of failure. So by doing this, once we get them shrink down, we don't have to worry about that. You always want to pull them though and make sure you've got a good connection made. On our yellow wire here we'll add it in and again on the passenger side, you're just going to be using the green wire instead. And then we're going to use a heat gun to shrink these down. You could also use a mini torch or you can use a lighter, just be careful not to overheat them. What we want to do is just warm them up. They'll start to turn clear and then you'll see them start to shrink and we want to do this so that our wire, it looks like it gets larger, almost like the butt connector magnifies it. And then you'll have a little clear gel that comes out of here.Now their excess wire, I always like to keep it around. Just gives us something to use down the road if we ever needed to change anything. But I do like getting it bundled up and out of the way, just like that. So it's nice and neat. Now the next thing we'll do is just go over to that passenger side. We're going to repeat the same process, but again, green to green, rather than yellow to yellow.Now, once you have your lights installed, of course you want to test them. So we're going to hook it up to our battery tester here, our trailer tester here. You can just as easily use your tow vehicle. We'll start by turning on the running lights. We see those are working really well, switched to the left turn signal, check our brakes and our right turn signal. It's like everything's working as it should. So we've got this installation taken care of. We're ready to hook up to our vehicle and enjoy our trailer..

I used these to replace the tail lights on my utility trailer. They are bright and because they are LED they will not require any attention. I look forward to many years of reliable service.



by:

This is an exact replacement for the light that we had, fit easily.

This is a review of etrailer as the product is 4*. The lights came loose in a box so all 4 lights lenses are scratched. When you spend 16-21$ a light you expect them to handle with care but they don’t.



by:

Great product. Did not listen to my salesperson Jesse. I do need the 2 prong adapters.

Purchased these in April, installed in May. Second trip I made with the trailer in July, the lens fell off one light. No damage, it just fell off.
Neither E-trailer, nor Peterson will warranty the light.
I think it's the last time I spend money with either of them.



by:

Exactly what you'd expect. Seems to be a good quality grommet-mount LED light. I used it for a mid-ship marker on a gooseneck.



by:

Two of the three lights I installed randomly turn themselves off. At times they also require multiple “touches” to operate, which can get frustrating.



by:

The light is very bright and is good quality I love it



by:

Good product, nice bright led's
Should
last a long time. Great customer service and good website description of product. Etrailer has always been a great company to deal with. Keep up the good work.



by:

perfect timing on the ETA of parts Thanks alot



by:

Very nice looking lights. Disappointed in that I did not watch the video to see that a harness is needed to wire the lights. I will get them with next order though.



by:

Exactly what we were looking for. I do think the description needs to be more clear as I ordered an extra wire that actual came with the light. Other than that received the product earlier than expected and we were able to finish the job for the customer sooner.



by:

Easy installation. Working perfectly after 1year



by:

I was worried that the backup lights would not be bright enough, but they’re surprisingly bright for only one segment of the light.



by:

Easy instillation and very bright. But you must be very thorough that you have the right sized grommet for the hole in the bed or trailer AND for the light you are using. Not all grommets are the same as with trailers and flat beds so make sure that you double check the hole size both ways of the bed and the light to minimize head aches when you go to install.



by:

Thank you for the prompt service.



by:

These worked great



by:

Great light but would need to manually turn them on each time you kill the main switch in the horse trailer. Will reorder the same light but without the touch switch in the middle of the lens. Bad on me for being a poor electrician.



by:

Perfect replacement for my damaged tail light on our new Timpte 720 aluminum car hauler. Shipping was very quick and packaging was perfect. Thank you for the great service.



by:

Sure would’ve been nice to know the mounting flange and enclosure is plastic.... not one place in the description or video.... disappointed



by:

Very nice lights bright
