This all-in-one round LED light takes care of five key functions in one clean package—stop, tail, turn, backup, and warning light. With 20 diodes inside a 5-1/2" diameter housing, it puts out a smooth, even glow that’s bright and easy to see. The design uses an outer red band and inner LED zones that switch colors depending on the function, so you get crisp brake lights, clear white backup illumination, and amber warning flash when needed. It’s a simple way to streamline lighting without adding extra fixtures.
If your trailer sees rain, dirt, or water crossings, this light is built to handle it. The housing and lens are sonically sealed into a single waterproof unit that’s fully submersible. Durable surface-mount technology (SMT) keeps the 20-diode circuit board protected from shock and vibration while improving heat distribution. The polycarbonate lens and body add strength so it won’t crack or fog up over time.
Wiring is straightforward but flexible for those who like clean installations. Each function has its own lead—black for tail, red for stop/turn, brown for backup, blue for flash pattern selection, yellow for syncing lights together, green for amber warning, orange for white warning, and white for ground. You can even synchronize up to four flash patterns between multiple lights for matching effects across your trailer or setup. The 8" hardwire leads make connection easy right out of the box.
LEDs outlast incandescent bulbs by up to 50 times while pulling far less current. That means more reliable performance, no burnt filaments to replace, and less strain on your electrical system. At 12V operation, these LEDs deliver bright output with minimal power use, keeping your rig visible and efficient on the road or at the job site.
Installation stays neat thanks to the flush-mount design with a built-in black flange. Once mounted, it sits tight and low-profile at just 1" deep with a 4-5/16" light face diameter. It’s DOT compliant and meets FMVSS 108 requirements for automotive lighting—ready to go wherever you need reliable illumination that looks good and performs even better.

Hello everybody, this is Jeff at etrailer.com. Today, I'm gonna take a look at the Optronics Round Fusion LED Hardwired Stop/Tail/Turn/Back-Up, and Warning Trailer Light. Has the red and the clear lens. Now, this is a round trailer tail light. It has a nice smooth bright red exterior and it serves five functions. And I do have this hooked up to some 12 volt power, so we can go through those functions and show you what they look like.
So, I'm gonna first turn on our 12 volt power and you'll see the first function comes on as the tail lights. We'll go ahead and turn off the overheads, and there's your tail light function. You can see what it is, is outer band of 10 red LEDs that light up. And then when you apply your brakes, you notice those same 10 red LEDs will brighten to let people know you're apply your brakes. And then if you turn on your turn signal, you can see that same outer band of the same 10 red LEDs will brighten and flash to let them know what direction you're turning in.
And the other feature is gonna be the back-up light. So, what we're gonna do with that is we'll take our, hook up our back-up light and then just to show you when you go into a reverse, what's gonna happen, you'll see that center white X lens right there, it's a clear lens. For the back-up light, there's six white LEDs there that you'll notice will light up very bright. So when you go into reverse, it'll let people know behind me that you're going to back up. And then what's unique on this light, what I wanted to show you was the, it has a orange and a green wire and those will hook-up to a warning light if you wanna have a warning light on this light here.
If you take the green wire, that's gonna give you an amber warning, and I just wanna show you that. If we hook-up the green wire, and you hit your warning, you'll see that the green wire's gonna get you four amber LEDs that'll flash as a warning light. Very bright. And then the orange wire we mentioned, if we hook that one up, again, just separately, and if you turn on your warning function, you'll see that it's gonna get you those six white LEDs in the same center lens there, lighten up in a flashing there. Now, if you hook both of them at the same time, the green and the orange, you'll notice what's really nice, it'll get you a warning light that'll alternate.
In other words, you're gonna have the four amber LEDs, and then the next one is the six white LEDs, so they'll go back and forth between the two. So, it gives you a nice warning light function. Now, this light has 20 LEDs total on it. It will get you four flash patterns and can be synchronized with multiple lights on the vehicle or trailer. And it is, they do have two wires, a blue and a yellow wire that we'll go through at the end here. I'm gonna go through all the wire colors and tell you what they do. Turn off our power, turn back on our overhead light. We'll disconnect this. But before I go through the wires and the colors, what I wanna go through is some features on this light. It is a sonically sealed waterproof housing and lens unit, which makes it submersible. It does use durable SMT Technologically which is Surface Mount Technology. And that's the construction of the LED circuit board, it'll let you better withstand shock and vibration, and allows for improved heat distribution. We mentioned they use LEDs in this light, so they do make great replacements for incandescent lights, 'cause they'll last 50 times longer, they're more efficient, 'cause they'll provide brighter light with less power output, and of course no bulbs to replace or brittle filaments that are gonna break. And you do get lifetime warranty on the LEDs. You can see it has a red lens, has an inside clear X lens in the middle, uses red, white, and amber LEDs. Basically, the red lens will have red LEDs for stop, tail, and turn. The clear, we showed you, lens, has white LEDs for back-up, and also white in the amber LEDs for a warning light. This is a flush mount design light, you can see it comes with the built-in black flange. It does have the three holes that you put your screws in. Now, it does not come with mounting hardware, you would have to supply that. It is hard-wired, it's all ready to install. The wire length is about eight inches. And now we'll go through the colors of the wires I mentioned. Basically, what we're gonna have here, is we'll start with the black wire and the black wire is gonna be your tail light wire. The white will be your ground wire. The red wire is gonna be your stop and turn. And the brown is your back-up light. And then we mentioned the green, that's gonna get you the amber warning feature. The orange will get you the white warning feature. And then we mentioned the blue and the yellow, those are the two that you'll hook-up. The blue will get you the different flash patterns if you want to switch. And the yellow will sync if you have other lights that you wanna hook-up on your vehicle or trailer. This yellow will sync all the lights together that have these features. This light is DOT compliant, Department of Transportation Compliant, does meet the Federal Motor Vehicle Safety Standard 108 Requirements for automotive lighting. It is a 12 volt light. Last thing is just give you a few dimensions. We're gonna do the overall diameter, including the mounting flange, so there's 5 1/2 inches. The light face, just the light face is 4 1/4 inches. And the depth of it right at one inch deep. But that should do it for the review on this Optronics Round Fusion LED hard-wired stop/tail/turn/back-up, and warning trailer light.

was delivered to the wrong place but was someone that knew me and brought it to me along with another package from another vendor. but not your fault.
Need for later
Bright light for tail, brake/stop, and back up are an excellent upgrade to the trailer.
Good products exceptional service
Awesome tail lights! Bright for brake lights and bright for reverse lights backing up
This product is the missing link of the trailer market. There is no equivalent.
Shipping to Canada was fast and hassle free.
I strongly recommend the product and the seller.
Great Lights, Diodes all remaining bright, Would Highly recommend
Awesome tails much nicer updated look on my service truck
One of the best trailer light kits I've ever had. Perfect fit for my trailer. Being able to have back-up lights now is a game changer and long overdue.
Very well made and I have no reservations that these lights will last a long time. I like the fact that they aren't overly bright while in running mode. Don't want to give an impression that brake lights are on until they are. When they are applied and ON there is no mistaking. Wonderful lights. Affordable and well made.
I bought a similar product on eBay and this one is much brighter, well worth the extra money!
Good all-in-one lights replaced my old old incandescent lights. Really visible. Works great. Plastic housing seems like it could be susceptible to damage.
These work great and fixed the problem with my truck and its trailer management system. I was having issues with a cheaper set I ordered from another site. My truck's fancy trailer management system would think there was a fault and cut power to the trailer lights. I replaced the lights with these and so far so good. Thank you!
Lights worked perfectly and it was very easy to I stalled.
You always have what I’m looking for. Good product, and got it quickly
Great product. Easy to install. Definitely recommend this product.
Great quality light. Replaced old incandescent lights with these LED lights on my boat trailer. They are much brighter.
Had to wing it since the wires weren't all the same color, but it appears this was the exact part I needed!
Exactly what I was looking for & super fast response along with shipping
Great upgrade in brightness for my 2019 Keystone Cougar. Wiring was accurate. Always the only issue for me is clean caulking...but that's a me issue
Added this to our Arcimoto that we converted to a flatbed. The electronics is driven by Pulse Width Modulation coding in an MRS Module and we don’t have the code. So we had to buy these with less draw (due to less LEDs). They work perfectly. The backups work perfectly (which it had none but the wiring was there). Probably the best lit Arcimoto in the world :) High quality. Fit in the grommet and bracket from another set of lights that had too much draw - so that shows these are very standard size. Pics show no backup, then backup. They are bright!
These are a perfect replacement for the old lights on my Aliner. Had them wired up in not time. The only thing that presented a problem is that they mount flush. This means that the wires have to line up with wiring holes on a camper. With an Aliner there is one hole for each side, but they are offset to the right. My solution for this is to make risers with cutaways for the wires to run in to the offset holes. I'm using plastic cutting board material to make the risers.
Great price, good quality. Worked great to rig up my RV receiver hitch toolbox with lights.
Love the super crisp color temperature and brightness and the reverse light. I've used a ton of Optronics products over the years and have never had one fail. I think these might be my favorite trailer lights yet!
Wires not identified you have to go to website to confirm which wires are what. Other lights I have purchased were tagged
Quick shipping and everything arrived in great condition. These are going to look great on the back of my 2005 Jeep TJ
