Features to know about

Brighter and More Efficient Lighting: Fusion LED Design

This Fusion LED tail light is built for better visibility with less power. It uses 16 LEDs that serve four functions—stop, tail, turn, and backup—so you get everything you need in one compact 7-1/2" x 3-1/4" oval light. At 12.8 volts, it draws only 0.265 amps for stop/turn, 0.24 amps for tail, and 0.3 amps for backup. The red lens is set inside a clear lens with both red and white LEDs, giving you crisp illumination day or night without the energy drain of old incandescent bulbs. No filaments to break, no bulbs to replace—just long-lasting performance that stays bright.

Dealing with Water Exposure: Fully Submersible Construction

If your trailer sees rain, puddles, or full submersion, this light is ready. The housing and lens are sonically sealed into one waterproof unit that keeps moisture out and protects the internal diodes and circuit board. Whether it’s launching a boat or towing through wet conditions, you won’t have to worry about corrosion or water damage cutting your trip short.

Built to Handle the Rough Stuff: Durable Surface-Mount Technology

Rough roads and vibration can kill fragile lights fast, but this one is built tougher. The LED circuit board uses surface-mount technology (SMT) for added shock resistance and improved heat control, which means a thinner profile and longer service life. The durable polycarbonate housing and lens add another layer of protection against impact and stress from constant use.

Simple Setup Without Cutting Holes: Surface-Mount Installation

Mounting this light takes less work because there’s no big cutout required. It installs flat against the trailer using its built-in black flange—hardware not included—and the 4-wire pigtail makes wiring straightforward: white for ground, brown for backup light, red for brake/turn, and black for tail. With an 8" lead length and standard 18-gauge wires, it’s easy to connect cleanly without extra adapters or guessing which wire does what.

Optronics Fusion LED Trailer Tail Light STL211XRFHB installed flush on trailer surface, showing surface-mount design and compact oval housing.

Compliant and Reliable Performance: Ready for the Road

This light meets DOT, FMVSS 108, and CMVSS 108 standards for automotive lighting, so it’s not just bright—it’s road-legal anywhere you tow. With LEDs that last up to 50 times longer than traditional bulbs and a lifetime warranty on the diodes, it’s a dependable upgrade that keeps you visible and safe mile after mile.

Perfect replacement, fits and works gre at



by:

The gasket around the light itself is plastic. It would be much better if used if a rubber grommet fitting. But the LED light is perfect for visibility. The white/clear reverse light is great when backing.



by:

It's a great light! Just be aware that the backup light won't work with a 4-flat wiring harness. I didn't know that, and now I have to add an extra line just for the reverse light.



by:

These lights are fantastic and a direct replacement on my EZ Loader boat trailer. Just had to drill the screw holes and attach wires. Done deal.

The LED lights are good and bright, and the back up lights serve their purpose perfectly.



by:

Time from purchase to receiving time took long, about 1 week before it shipped, then arrived 3 days after it was shipped.



by:

This transaction has been some of the best communication I have had with online ordering with updates at each step along with super speedy shipping and delivery. I would highly recommend this seller and give this an A+++++++++++++++++++++++++++++ rating. THANKS!!!!!!!!



by:

It was an easy install since my trailer wiring harness already had the wire there for the backup lights (on my trailer you only get the backup lights if you buy the more expensive $$$$ upgrade package from the factory). For basic safety reasons I think travel trailers should have a backup light anyway. Lights are surprisingly bright and I would do this again since it was relatively easy. Also,those WAGO wire connectors with some electric tape made this job go very smooth and know that my connections are secure.



by:

Web site is so easy to use. Parts are available and ship quickly. Kept in formed through the shipping process. Items arrived when scheduled. Have very please with the performance of the LED tail light.. 5 stars for this company and customer service...

Still working great

Got the lights I was looking for!



by:

Perfect for upgrading or replacing tour taillight



by:

I purchased these to spruce up an old fold-out tent trailer that I bounce around out in the hills. They were easy to install and draw almost no current compared to the old incandescent lamps.

I wired it so when I'm camped, I can run the reverse lights on the trailer battery to light up the camp site instead of having to carry around a flash light.

Great value, and they work well also. You can't go wrong with etrailer lights.

OK, its been a year now so let me tell you what I think. These are just as bright as the day I installed them on the trailer. The plastic lenses are still clear where theyre supposed to be clear and red where theyre supposed to be red. Nothing has faded or cracked. As trailer lights they are working great. As camp lights its working as planned. Im still saying these are a great value. Order them, you wont be disappointed.



by:

Ordered these originally however they sent me tiny marker lights instead. Contacted Ashley, she fixed the issue fast and expedited the correct ones. Nice lights, bright and it's nice having backup lights built in



by:

It was what i was needing and no one else had it.



by:

I didn’t realize this price was for one single taillight. I’ve never purchased taillights that weren’t in a set. Should maybe clarify that a bit more on the description



by:

Running strong. The original was broken off beyond repair. These lights last a long time, you can almost rule out the light during troubleshooting.



by:

Great phone service in matching my needs.
Fast
delivery. Just the right item.



by:

Exact replacement to original that came with our cube truck. Ordering was easy and shipping was lightning quick. Thank you very much!



by:

Used these on my 1985 custom pickup truck flatbed conversion, they look good and are very bright. Only complaint is that the wires come out of the unit in a "straight line " so you either have to "mill" a slot in the mounting panel or drill a large hole.



by:

Please see attached photos of my lights installed on a trailer.

These lights are a direct replacement for the stock optronics stop/turn/tail lights on my Sundowner horse trailer. It was pre wired from the factory for backup lights but none were installed. If you pull off the rear right side light cover of the trailer there is a yellow wire that is capped off. Double Check with a light tester that it is the power wire for reverse lights. I drilled out the old rivets and installed the new lights with the reverse light wired up to the yellow power wire

The leds are nice and bright for all functions



by:

I just got a new boat and had damaged the trailer light no other place around had a matched light even the large outdoor shop (starts with a C) sold me the incorrect ones for $60. Then as frustration started impacting me. I saw etrailers online, saw a light that was identical, took a chance and it was the exact light for only 1/3 of the price I paid at the large outdoor store. End result, I'm very pleased with my purchase, shipping and overall.



by:

Perfect replacement. As advertised!



by:

I bought this set to install on the back of my enclosed overland trailer.
On occasion, i carry a basket in the trailer hitch location and my stock lights get covered. The Fusion LED lights were easy to install, very durable and are super bright. At night you can see them from a great distance!



by:

Unlike the cheap Amazon LED lights, this one is actually submersible and water tight. Just mount and connect.



by:

Good replacement for an existing light on our travel trailer. Trailer was wired for backup lights but none installed. This unit will give me tail, turn, brake and backup lights.

Measurements for mounting holes was exact. Did not have to drill other holes. This is a surface mount. I did have to modify the reflective trim ring that was on my original light for it to fit the new light. The housing on this light was slightly larger but the overall dimensions were the same.
Some grinding on the trim with the drimmel tool solved the problem.

Would be good for initial installation also. Initial installation would require a hole near the center of mount location to allow wiring to pass through trailer. Seems to be a quality product.

Attached photos of lights installed.

Lights are still functioning as they are supposed to. Have had no issues with them.

I like the looks of them! I hope they last!
The original led tail lights have been replaced twice in 6 years. That’s unexceptable!

  • Reverse Lights for 2018 Ranger Bass Boat Trailer
    Hi Gary; are you trying to replace existing lights or add standalone reverse lights onto your 2018 Ranger boat trailer? The GloLight LED Backup Light # BUL111CFPG is a single light, and measures 7-1/2" long x 3-5/16" tall x 1-1/8" thick. If you want tail lights that have reverse light functionality something like the # STL211XRFHB would be a better choice. Most of our lights like these are sold individually. Typically if it is a pair of lights we show two lights in the pictures. If you...

  • Does the Amount of Diodes in an LED Dictate Overall Brightness
    The number of diodes can help make an LED brighter but the diodes can also be brighter or dimmer themselves so it's not totally dependent on the number of diodes. I've seen really big single diodes that are super bright outshine lights with several diodes. Like I have LED headlights in my car and they are one really big diode and they incredibly bright.

  • Availability of Fusion LED Trailer Tail Light STL211XRFHB with 5 Wires
    Hey Jesus, thanks for reaching out! We have the Fusion LED Trailer Tail Light # STL211XRFHB which is the exact part number you're looking for. Just add this light to your online cart and be sure to adjust how many you're needing before making your purchase. I'm not sure what a 5th wire would do in this kind of situation because these lights only have the stop, tail, turn, and backup functions - and the stop and turn functions are on the same circuit so it only requires 4 wires.

  • Power Issues When Installing LED Lights to Replace Incandescents
    The Fusion LED Trailer Tail Light - Stop, Tail, Turn, Backup - Submersible - Oval - Red/Clear Lens # STL211XRFHB will function off the same 12V of a van as the 12V of a trailer so you shouldn't have any issues.

The light itself measures overall 7-1/2" wide x 3-1/4" tall x 3/4" deep. The light face is 6-1/2" x 2-1/4". It uses a 4 wire connection.

    Do you mean it has two white wires in addition to the power wires for the turn/brake and running lamp circuit? If so you can simply attach the ground wire for the # STL211XRFHB lamp to both white ground wires on the trailer. This assumes they're both ground wires.

    Thank you for the info! It sounds like your tail lights have the stop, turn, tail (running), and reverse functions similar to the Fusion LED Trailer Tail Light # STL211XRFHB.

  • Comparing Fusion LED Trailer Tail Lights Part STL211XRFHB and Part OPT37FR
    The main difference between the Fusion LED Trailer Tail Light part # STL211XRFHB and the Fusion LED Trailer Tail Light part # OPT37FR is that the stop/turn signal portion of the former is a red lens with red LEDs and the latter is a white lens with red LEDs. The white lens with red LEDs will be brighter/clearer hence the price increase. I recommend the latter as our best option for clarity.
