This 4-5/16" round Fusion LED light packs five essential functions into one clean, waterproof housing. It serves as a stop, tail, turn, backup, and warning light—all in one unit. The outer red band brightens for braking and tail lighting, the inner X flashes amber for warnings or white for turn signals, and the center LEDs handle backup duty. With 20 bright diodes running at 12V, you get a complete lighting setup that’s easy to wire and ready to go.
Built for real-world conditions, the sonically sealed housing and lens are completely waterproof and submersible. That means no moisture intrusion, no fogging, and no corrosion inside. The durable polycarbonate body resists impacts from debris and road spray while keeping everything watertight. Whether it’s a downpour or dunking at a boat ramp, this light stays protected.
The 20 LEDs use surface-mount technology (SMT) to handle shock and vibration better than traditional bulbs. There are no filaments to snap or bulbs to replace—just solid-state reliability that lasts up to 50 times longer than incandescent lights. The design also improves heat distribution, so brightness stays consistent even during long hours of use.
Installation is straightforward thanks to the built-in recessed grommet mount and pre-wired pigtail with labeled leads. Each function has its own color-coded wire—black for tail, red for stop/turn, brown for backup, blue for flash pattern selection, yellow for sync, green for amber warning, orange for white warning, and white for ground. With an 8" wire length and compact 1" depth, it fits neatly without sticking out or requiring special adapters.
When multiple lights are used together, their four selectable flash patterns can be synchronized through the wiring. This makes it easy to create consistent warning signals across your setup for better visibility and safety. DOT compliant and meeting FMVSS 108 standards, it delivers dependable performance that’s both bright and legal wherever you travel.

Hello, everybody. This is Jeff at etrailer.com. Today we take a look at the Optronics Round Fusion LED Hardwired Stop Tail Turn, Backup and Warning Trailer Light with the Red and the Clear Lens. Now, this is a round trailer taillight, has a nice, smooth bright red exterior, and this light will serve five functions. And I do have this hooked up to some 12 volt power, just so we can go through those functions. So the first function is gonna be the tail light.
So I have it hooked up, and we'll go ahead and turn on our 12 volt power. And you can see the tail light would come on. Go ahead and turn off the overhead lights. And there's your tail light function. Basically, the outer band of 10 red LEDs will light up.
And then when the brakes are applied, you'll see those same 10 red LEDs get brighter. So your brakes are (indistinct). And now when you do hit your turn signal, same way. It'll be the 10 bright red LEDs, but it'll be getting brighter and flashing. And then, if we go to the backup light, just wanted to show you, we'll hook up the reverse light.
And with that hooked up, what you'll see when you go into reverse, you'll see that center clear X lens right there. Basically, there's six white LEDs in that that'll light up, so that lets the people behind you know that you're going into reverse. And also what's unique with this light, it does offer a warning light. And I'm gonna try to show you that. But basically, there's two wires on the warning light.
There's a green wire and an orange wire. If we hook up a green wire, and then what you'll notice is, lemme go ahead, and you'll see that it's four ambers in that center clear lens that'll start flashing for a warning light. Now, if I go ahead and hook up the orange wire, what you'll notice for that warning light, it's gonna be six white LEDs that are gonna flash as a warning light. And then the last one, if I do both of them together, if we do the orange and the green together, which you'll notice when I go ahead and turn on the warning light, you'll see that they'll alternate. So you'll get your four amber flashing, and then your six white flashing in the middle. So there is a total of 20 LEDs on this light. It does offer, let me go ahead and turn back on overhead light, it'll offer four flash patterns that can be synchronized with multiple lights connected, by attaching the blue and the yellow wires. So for right now, I'm gonna go ahead and turn off the power. Disconnect everything. Now, this light is a sonically sealed waterproof housing and lens unit, which makes it submersible. It does use the durable SMT Technology, which is Surface Mount Technology. That's the construction of the LED circuit board on this light. It'll better withstand shock and vibration, allows for improved heat distribution. And we mentioned they use LEDs, that'll 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, no brittle filaments that are gonna break. And you do get a lifetime warranty on the LEDs. Now, as I mentioned, you can see it has the red lens, has the inside clear X lens, and it uses red, white, amber LEDs. Basically, that red lens has the red LEDs for stop, tail and turn. The clear lens has white LEDs for backup, as we showed you. And also, in that clear lens has white and amber LEDs for the warning lights. Now, this a recess grommet mount design to install this. Now, the rubber grommet to install this is not included. We do sell that separately on our website, and it's a part number A45GB. You can see this is hard wire, with all the wires ready to install. Wire length is eight inches. And just quickly to go through them all, the black wire is for your tail. White is for your ground. Red, stop and turn. Brown for your backup. And then, the other four remaining wires we had gone over briefly. The green wire is gonna be for the amber warning. The orange wire is for the white warning. The blue we mentioned is for the flash pattern connection. And the yellow is for the sink wire. This is DOT compliant, Department of Transportation compliant. Meets the Federal Motor Vehicle Safety Standard 108 requirements for automotive lighting. We mentioned the voltage for this is 12 volts. Last thing is just the measurement on the light itself. The diameter, one into the other, is four and a quarter inches. And the depth, right at about seven eighths of an inch. But that should do it for the review on this Optronics Round Fusion LED Hardwired Stop Tail Turn, Backup 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!
Wires not identified you have to go to website to confirm which wires are what. Other lights I have purchased were tagged
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.
Quick shipping and everything arrived in great condition. These are going to look great on the back of my 2005 Jeep TJ
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!
