Optronics STL211XRFHB Fusion LED Combination Tail Light Diagram

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

Fusion LED Trailer Tail Light - Stop, Tail, Turn, Backup - Submersible - Oval - Red/Clear Lens - STL211XRFHB

Average Customer Rating:  4.8 out of 5 stars   (31 Customer Reviews)

7-1/2" x 3-1/4" Oval. Waterproof light serves 4 functions: brake, tail, turn, and backup light. Red lens is set inside of clear lens. Mounts on surface of trailer with built-in flange - hardware not included. 4-Wire pigtail. 16 Diodes.


Great light. Would have like to see a rubber gasket around this for a better seal. But all in all a good light. 385584




The quality of the light was good. I did have trouble understanding if it would be two lights or one. I opted to order only one in case it was a set and now have to order a second. 919099




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. 789584


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. 734484

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.

Great products 718158


This is the second time ordering from etrailer. Both experiences have exceeded my expectations. Items were as described and arrived quickly. Customer service is great too. This is the place to go for all your trailer needs. I highly recommend. 711131


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. 668967


Nice lamps . Real bright. 663138


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. 658879


Installed on boat trailer a year ago. Super bright and works great. 639583


Good 603682


What a great product. I have had these for a year and they work great! 562308


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. 554361


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 486302


A clean and simple light that's easy to lnstall at a great price 475297

well one out of 6 as failed now Im not sure if there worth the money
craig l - 02/13/2019



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. 392556

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

Fair prices, fast shipping, and handle returns well. Good company to deal with. 387546

  • 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. There is a difference in amperage when using LED lights as they don't draw the same power, so if you are getting flashing then you will use the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 # P230004A-2 or the Optronics Load Resistor for LED Lights - Male PL-3 Plug and...

  • What Functions Would Tail Lights with 4 Wires Use
    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. This means that one wire is for the stop and turn functions, one wire is for ground, one is for the tail/running function, and the other wire is for the reverse function. The light that you sent in a picture of doesn't look like anything we have on our site so I'm not able to confirm what wires are for what functions...

  • 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.

  • 7-Way Connector and Fusion LED Trailer Lights Functions by Wire Color
    I can tell you which wires on each the light and plug are for, though you will want to use a circuit tester such as # 40376 to verify the functions. The the Fusion LED Trailer Tail Light # STL211XRFHB has a 4-wire pigtail. The white wire is ground, brown wire is backup light, red wire is brake light and black wire is tail light.

  • How Many Lights Are Included with Optronics Fusion LED Trailer Tail Light # STL211XRFHB
    The Optronics Fusion LED Trailer Tail Light # STL211XRFHB referenced in your question is sold as a single unit. If you need the pair you will just want to order 2 when checking out on the site. This is a really nice LED tail light with stop, tail, turn signal, and backup light functions. It features durable surface-mount technology to better withstand road shock and its sonically sealed waterproof housing is submersible. I have attached a short video review that you can check out as well.

  • Installing the Fusion LED Trailer Light # STL211XRFHB on a 2017 Subaru Impreza
    To install the Fusion LED Trailer Light # STL211XRFHB on your 2017 Subaru Impreza I recommend using the Deka Bonded 4 Wire # 16-4B-1 which is sold by the foot.

  • Replacement Taillights for 2002 Jayco Eagle
    I'd love to help you replace those assemblies so you can fix up your camper before your husband comes home, and we almost certainly have taillight assemblies that will work for you, but there is no way for us to know exactly what assemblies are on your 2002 Jayco Eagle trailer; trailer manufacturers do not keep those kinds of records for us to access and on an '02 trailer there is a high likelihood that the light assemblies have been changed over the years.

  • Wiring Optronics Fusion STL211XRFHB LED Trailer Tail Lamp
    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. You might want to use a circuit tester like # 40376 on both wires as you test all the taillight functions to make sure they're both ground wires.

  • 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.
