Features to know about

Brighter, Longer-Lasting, and Efficient: Dual-Face LED Lighting

This 4-1/4" round Optronics light uses 42 LEDs—21 on each side—to deliver solid, bright illumination for stop, turn, tail, and parking functions. The red and amber lenses work together so that both sides light up when braking, making your signals easier to see day or night. At 12.8V it draws just 0.360 amps for stop/turn and 0.030 amps for tail, using much less power than traditional bulbs. With no filaments to break and no bulbs to replace, these LEDs last about 50 times longer than old-style incandescent lights.

Built for Wet Conditions: Fully Submersible and Sealed Design

Water intrusion is one of the fastest ways to ruin a trailer light, but this unit doesn’t let that happen. The housing and lens are sonically sealed into a single waterproof piece so the internal diodes and circuit board stay dry even when the light is submerged. That makes it a great fit for setups that see rain, spray, or complete dunking at the ramp. Once installed, it stays protected from corrosion and short circuits caused by moisture.

Stronger Build for Rough Roads: Die-Cast Metal Housing

Instead of plastic, this light uses a durable die-cast steel frame that stands up to vibration, bumps, and regular use without cracking or flexing. The LEDs are mounted with surface-mount technology (SMT), which helps dissipate heat and resist shock. That means dependable operation in tough conditions where fragile lights usually fail.

Straightforward Mounting: Single Post with 3-Wire Hookup

The pedestal-mount setup makes installation simple. A single 12 mm post secures the light solidly in place, and the 3-wire pigtail runs through the post for a clean look—black for running lights, red for stop/turn, white for ground. Hardware is included, so once you drill the mounting hole you’re ready to bolt it down and wire it up.

Reliable in All Directions: Five Functions in One Compact Unit

This dual-face design covers five lighting functions—stop, front and rear turn, tail, and parking—in one sealed housing. With bright amber LEDs facing forward and red LEDs facing back, it adds visibility from both sides without doubling your wiring or mounting points. It’s DOT compliant and built to keep you visible wherever you go.

I RECENTLY BUILT A CUSTOM TRIKE. THIS LIGHT WORKED
PERFECTLY WITH THE TWO SIDES. I MOUNTED THE LIGHT HIGH SO IT WORKED AS A REAR AS WELL AS A FRONT TURN SIGNAL. THE LED AND THE CHROME MAKES IT LOOK VERY NICE FOR
CUSTOM VEHICLES. JUST WISHED THEY WOULD MAKE A SINGLE FACED ALSO.

Awesome product. Very heavy duty!



by:

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.



by:

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



by:

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.



by:

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?



by:

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.



by:

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.



by:

Good quality



by:

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!



by:

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.

Awesome!

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.
