This 4-5/16" round Fusion LED light packs four essential functions—stop, tail, turn, and backup—into one clean, waterproof unit. The outer band of 20 red LEDs powers the brake, tail, and turn functions, while the white center LEDs handle backup duty. It keeps everything bright and easy to see, even in poor lighting. You get dependable illumination that meets DOT and FMVSS 108 standards for visibility and safety.
Incandescent bulbs burn out fast and draw more power. This sealed LED light fixes that problem with diodes that last up to 50 times longer and use less current at 12V. The solid-state design means no filaments to break, no bulbs to replace, and steady brightness every time you hit the brakes or shift into reverse. It’s a simple upgrade that just works.
Water damage ruins lights fast, but this one is ready for the elements. The housing and lens are sonically sealed into a single waterproof piece that’s fully submersible. Whether it’s backing into water or traveling through driving rain, moisture stays out. The durable polycarbonate build holds up against vibration, impact, and corrosion.
Installation is straightforward thanks to the color-coded wiring—black for tail, red for stop/turn, brown for backup, white for ground—and an 8" lead length that gives you room to work. It’s designed for a recessed mount using a rubber grommet (sold separately) to create a clean finish. Once it’s in place, you’ll have a reliable light that looks sharp and performs consistently over time.

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Optronics Round Fusion LED Hardwired Stop Tail Turn and Backup Trailer Light with the Red and the Clear X Lens. Now, this is a round trailer tail light. Has a nice, smooth, bright red exterior which will serve four functions. And we do have this plugged into some 12 volt power so I can show you those functions.
So if I turn the power on, you'll be able to see, you'll get your tail lights. Go ahead and turn off the overhead. There's your tail light function. And then, when you apply your brakes, you'll be able to see how that gets a lot brighter when your brakes are applied. And then, when you hit your turn signals, you can see that your turn signals will cause that to get brighter and flash.
And the last one I wanna show you is that center X lens. That is actually your reverse light or backup light. And if we hook that one up, you'll be able to see that when you go into reverse, you'll get the X lens all lit up and it's all white LEDs. There is a total of 20 LEDs on this. And again, there's your backup.
So we'll go ahead and turn back on our overhead lights. Go ahead and turn off our power. Now, this is an sonically sealed waterproof housing and lens unit, which makes it submersible. Does use durable SMT technology, which is the construction of the LED circuit board that'll better withstand shock and vibration, and allows for improved heat distribution. And as we mentioned, this uses LEDs, which make great replacements for incandescent lights.
They'll last about 50 times longer. LEDs are more efficient, 'cause they'll provide brighter light with less power output. And the big thing is there's no bulbs to replace or brittle filaments that are gonna break, and you do get a lifetime warranty on the LEDs. We mentioned it's a red lens that's set inside with this white X lens on it. So the red lens has the red LEDs for the tail light, and the clear lens has the white LEDs for the backup light. Now, to install this, it is a recessed grommet mount design. The grommet will go right around here. Now, the rubber grommet is not included. We do sell that separately on our website. It's part number A45GB. Now, this is hardwired and ready to install. You can see the wire length is about eight inches. And the wire configuration, the black wire is your tail. Your white wire would be your ground. Your red wire is your stop and turn. And your brown wire is for the backup. This is a 12 volt light. Last thing I'm gonna do is just give you the overall dimensions on it. So the diameter, from one end to the other, is four and a quarter inches. And the depth of it front to back is right about one inch deep. But that should do it for the review on the Optronics Round Fusion LED Hardwired Stop Tail Turn and Bckup Trailer Light with the Red and the Clear X Lens.
