This light covers you front and back with a red lens to the rear and an amber lens facing forward. Each side uses 21 diodes for a total of 42, giving bright, even illumination that’s easy to see in any direction. It handles stop, turn, tail, parking, side marker, and reflector functions in one 4-1/2" x 4-3/4" housing. LEDs are more efficient than old bulbs and give off a crisp light that helps other drivers spot your signals right away.
The housing and lens are fused together into a single waterproof unit that keeps moisture out. Whether you’re running in heavy rain or working around water, the sealed construction protects the circuit board and diodes from damage. You can count on this light to keep shining without fogging up or shorting out.
The die-cast steel body gives this light a solid feel and extra durability against vibration or impact. Inside, the LED board uses surface-mount technology (SMT) that holds up better to shock while spreading heat more evenly. It’s built for long life—LEDs last up to 50 times longer than incandescent bulbs and don’t have filaments to break.
Wiring is as simple as it gets—white is ground, black runs the tail circuit, and red handles stop/turn. The single post pedestal mount uses a 1/2" threaded post for secure attachment, and hardware is included. It’s designed for 12V DC systems and draws just 0.360 amps on stop/turn and 0.030 amps on tail, so it won’t overload your lighting circuit.

This Optronics light meets DOT requirements for visibility and safety performance. With its bright output, sealed body, and rugged build, it’s an easy upgrade that delivers dependable operation mile after mile. Plus, the LEDs are backed by a lifetime warranty for lasting peace of mind.

Today we're going to be reviewing part number STL53ARPB. This is the dual-faced red and amber post-mounted LED light for the right-hand side of your trailer. It's going to feature the dual face design. This is for the passenger side trailer light. The red side is going to serve three functions, such as your stop, turn and tail light and the amber side is going to serve two functions, such as your park light and rear turn signal light. It's also going to feature the built-in amber side marker light with the Reflex reflector. This unit's going to feature the long-lasting LEDs that are great replacements for incandescent lights.
They're going to feature a multi-diode design that's going to optimize your light output. You don't have to worry about replacing any bulbs and you don't have to worry about any brittle filaments. The LED system is going to be more efficient, which means it's going to provide a brighter light while using less power. It does have a corrosion-resistant design when it comes to the construction of the housing. Here at the bottom of the post you can see that it's going to expose a three-wire design. It's going to include your red wire for your stop and turn signal, your black wire, which is basically just your power lead, and then your white wire, which is going to be your ground wire and it has a little ring terminal on there.
That way you can attach it to any surface. This is Department of Transportation-compliant, so it meets FMVSS108 requirements in any 360-degree position. It's a nice square light. If we take a look at the overall measurements, it's going to give us a measurement of 4 1/2 inches wide by 4 1/2 inches tall. Now if we measure to the bottom of the housing, it's got a little lip down here, and it's going to extend our measurement to 4 3/4 inches tall. If we take a look at the depth, that's going to give us a measurement of about 2 and 1/4 of an inch. It's going to contain 42 total diodes, which are going to be the LED units.
That's going to be 21 LEDs per side. Here on the red side, the power draw for the stop signal is going to be 0.182 amps at 12.8 volts and for the tail light function, it's going to 0.012 amps at 12.8 volts. For the amber side, it's going to be 0.215 amps at 12.8 volts. Again, this is a pedestal mount installation. You're going to get the hardware that you need, so you're going to get a rubber flat washer, a regular flat washer. You're going to get a lock washer and you're going to get the nut.
The length of that pedestal is going to measure right at 2 inches. We're going to go and hook it up to our external power source. That way you can see what it looks like with power running to it, and with our overhead lights turned off. We're going to go ahead and make the ground connection which, again, is just the white wire. Then we'll connect the power lead, the black wire, and the stop and turn signal with the red wire. That power lead is just going to provide the power to the tail light function. You can see here it's going to send out a nice consistent LED signal. You've got the side marker light there and then you have the amber side as well. Really, I guess you're going to have 21 diodes per side and it looks like you're going have three for the side marker. Here on the red side, again, this side's going to provide three functions. You're going to have the tail light function, you're going to have your stop function. You can see how that illuminates for a brighter signal, and you're going to have the turn signal function. Here on the amber side you can see there that when we apply the turn signals, it's going to light up as well. The LED system is going to provide a nice consistent light and a very quick response time. That's going to do it for today's review of part number STL53ARPB. This is the dual-faced red and amber post-mount LED light for the right-hand side of your trailer. .

Came on time. Quality good. Nice and bright. Thanks, E-Trailer.
1 year in and they work great. I am very satisfied.
Very impressed. Very attractive. High Quality product. I wanted a metal fixture and I finally found it with your company and the myriad of products you let me choose from. Thank you.
These wired up very easily, work great ,and are extremely bright . The frame is metal and not plastic but they still cost way too much for LEDs
The led lights are bright ,a
Work well . Service and delivery was fast ; and the product was a good value. etrailer has served me well over the years I have been doing business with them. I would recommend them to anyone.
This light has 2 intensities (3 wires). The HIGH intensity is very bright and will be excellent for an amber dust light on the rear of my off-road buggy, which is why I bought it. The LOW intensity is not nearly as bright. Not quite sure what it's for - perhaps a parking light?
I I am very pleased with these lights. I installed then on my travel trailer as side markers. They are very bright, and I see them just fine in the rear-view mirror.
I made the mistake of trying to save a couple bucks and bought some junk trailer lights. They fell apart during installation. Then I bought these trailer lights. As soon as you hold them you know they are high quality. Thank goodness there are still companies proudly making durable, high quality products. Please don’t wast your time on anything else.
Good quality
Product received after proper mailing time by USPS; less than 7 days. The product purchased, two trailer lights, look to be very high quality. Inside the box: the two lights and nothing more. Great email updates while the product was ordered and then shipped. A very nice follow-up email arrived the day after delivery. Very happy to post a positive response.
We love them. They got wet when we put the boat in the water several times & they ARE waterproof! Love the bright LED lights (which are so much brighter that the old lights) & the wiring matched both our tow vehicles! They were a little pricey but in reality, you get what you pay for. These are high quality lights. Thanks!
I am very satisfied with my experience with etrailer. The parts I received appear to be very good quality. I have not installed them yet though as I am waiting on Hurricane Michael to pass through. However the lights do seem to be very solidly built. I needed this style and etrailer was the one that had it.
I like this light so much I bought one for my neighbor. We don't use them in the traditional way, we use them as "Dust Lights" on the rear of out Polaris RZR off road vehicles. In heavy dust, amber lights can be seen better than any other color. That is why they are required on all off road race vehicles. We don't race, but we do run high speed in dusty conditions and this light has saved the day on more than one occassion. You can see the light mounted on the left rear of the RZR in the attached picture.
Nice bright LEDs. I thought the housing might be metal but they are plastic. Nice long mounting stud. These replaced lights on top of a fender. The stud was longer than originals and very close to the tire but I didn't have a way to cut them off. Overall I am very pleased with the products and speedy service from e- trailer. I refinished my 35 year old tow dolly instead of buying a new one. New wiring harness lights and safety chains. $120 is much better than $1200 for a new one. Now it's ready for another 35 years.
All as described, well-packed.
Nice bright lights.
Met our expectations. Very happy
Everything was received in good order and in a timely fashion. I am pleased with the quality out of the box. I have not installed anything yet, but I anticipate that going well too. I read several reviews prior to ordering and my expectations were met in a very positive way. My initial experience has been very good. Thanks for the good service so far.
Super bright and easy to install. Hope the chrome plate (on plastic) holds up to the weather. Wish these came in black.
Great product. Fast shipping.
The LED light itself is great. Wiring/Mounting this unit was nothing short of a royal PAIN. I would not buy these again as a result.
This was a total rebuild of my triple axle trailer. I purchased several items for my boat trailer and have been very please with them.
The items were as as advertised and delivered in a timely manner.
The staff at "etrailer" is very courteous & knowledgeable.
I will continue to do business with "etrailer" as the need arises (hopefully I will not have to rebuild the trailer again).
So far there great.... perfect match to my fender lights.... the only thing to make them better is to have 6ft wire harness like kenworth
