Features to know about

Brighter Light, Less Power Draw: 16-Diode LED Design

Old incandescent lights waste energy and dim with age. This Fusion LED light uses 16 high-efficiency diodes that shine bright while pulling very little current—just 0.375 amps for stop/turn, 0.2 amps for tail, and 0.242 amps for backup at 12.8 volts. The clear lens with red and white LEDs gives crisp illumination that’s easy to see day or night. With no filaments to break or bulbs to replace, it stays reliable and efficient for years of use.

Worrying About Water Damage: Fully Submersible and Sealed

If your trailer ever goes near the water, this light is built for it. The housing and lens are sonically sealed into one waterproof piece, keeping moisture out of the circuit board and diodes. Even when submerged, it stays protected from corrosion and internal fogging, making it a solid choice for harsh weather or boat launches.

Simplifying Your Setup: 4 Functions in One Light

Instead of cutting extra holes for separate lamps, this compact 6-7/16" x 2-5/16" oval unit handles stop, turn, tail, and backup duties all in one. The built-in white LEDs take care of reverse lighting so you get plenty of light when backing up without adding another fixture. That saves space and wiring while giving your trailer a clean, finished look.

Easy Mounting and Wiring: Recessed Installation with Standard Plugs

Mounting is straightforward thanks to its recessed design that fits a grommet (A70GB, sold separately). It accepts industry-standard connectors—a 3-prong plug for the tail functions and a 2-prong plug for backup—so you can wire it up quickly without custom adapters. The low profile sits flush against the surface for a tidy fit that won’t snag or stick out.

Built Tough for Long Hauls: Durable Polycarbonate Construction

Everything about this light is made to last. The polycarbonate lens and housing resist impacts and road vibration. Surface-mount LED technology keeps the circuit board steady even on rough terrain while improving heat distribution. It’s DOT compliant and backed by a lifetime warranty on the LEDs, so you can count on it mile after mile.

These are bright LED lights, and having the LED back-up light in the center makes hookup very easy. The only problem I had was mounting the STL201RB light in the A45GB rubber grommet with the BK45BB mounting bracket. I tried following the etrailer videos with no success--in fact I was pressing on the light so hard in an attempt to insert it in the rubber grommet and mounting bracket that I was afraid I would break the light. So I decided to try a different approach. I mounted the grommet in the bracket (easy part), then immersed that assembly into near boiling water for about 10-15 minutes. This softened the rubber grommet sufficiently such that inserting the LED light into the softened grommet was now very easy. I used heavy gloves while assembling it, and rubbed a bar of hand soap around the inside mounting surface of the grommet just before inserting the LED light. Really worked well---just need to take caution when handling the very hot bracket and grommet assembly right out of the hot water bath. The attached picture shows one of the LED light assemblies, with associated wiring, just prior to checking out the electrical hookups to make sure the wiring was done correctly. The other picture shows the round LED light along with a small red LED side marker light after installation.

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!

Pulled old ones out and these jumped right in.. Easy-peasy. bright and pretty.
Had to run an extra wire to hook up the backup lights but that was not a problem.
YES buy these.



by:

These lights are the best I have found for truck lights, and I have tried many. We currently have every truck in our fleet outfitted with them and adding them to every new truck. We hook some of the white lights to the reverse lights and some to a work light switch. Eliminates the need to use an oval light for a reverse light.



by:

These are great lights. I wired in and utilized these on a utility trailer as tail-lighting. Good quality and value. I like the fact that these have back-up lighting build-in, which helps me at night while backing up the trailer.



by:

I was able to replace my existing lights with these that include the back-up light feature. Exact fit and work better than expected. Now I can see behind my 5th wheel when backing up the rig. The light harness along with the light fixture more than met all my expectations.



by:

Recently it was time to replace/ upgrade my boat trailer rear lights. I found exactly what I was looking for at etrailer. The parts I ordered were well described and fit exactly right for my application. I also ordered the wire pigtail connectors as I was adding lights with an integrated backup lamp. Installation was a breeze and all the parts seem to be high quality. I will definitely buy more items of etrailer in the future. Thanks for the parts.



by:

These lights worked very well for my older Rangertrail trailer. Instead of adding additional brackets for white lights, I could use the existing openings to add backup lights along side the brake lights. I have not tried the backup lights at a dark ramp yet, but they appear to be bright. The red brake lights are very bright in my garage. Shipping was fast and product was as advertised!



by:

Love them. Red LEDs are brighter than the ones I replaced and the reverse lights are really bright too. Now just hope they last longer than the ones I replaced. Those lasted two years up and down gravel roads on my welding truck. Glad I found this so I wouldn't have to mount extra lights in my bed because there isn't room. Great combo

Still working great. No complaints



by:

I chose the STL211RCB when I recently rebuilt a small trailer I use for my business. I wanted a fixture with a bright reverse light, while also taking up the least amount of space possible. This fixture exceeded my expectations, and has performed flawlessly since the day I installed them. The previous incandescent fixtures were always needing repair to keep them working. They were mounted low, and hard to see in the daytime. The small footprint of this fixture allowed me to relocate the taillight to a better position, allowing for better visibility, day or night. I would recommend these to anyone that needs to back up a trailer in the dark a lot.

  • Is there a Grommet for the GloLight LED Trailer Tail Light STL1211RCFHPG?
    Hey Todd, welcome back. The GloLight LED Trailer Tail Light item # STL1211RCFHPG doesn't have a rubber grommet because it's a flush mount with a trim ring. The Fusion LED Trailer Tail Light item # STL211RCB is a recessed light that is nearly identical though that does. The Fusion LED Trailer Tail Light item # STL211RCB measures 6-7/16" long x 2-5/16" tall x 1-1/2" deep. You will need the PVC Grommet item # a70gb to fit into a recessed cutout. Both the recessed light item # STL211RCB...

  • Recommended Wire Gauge for Installing Optronics LED Type Trailer Tail Light STL211RCB
    Super high-efficiency LED-type lights such as the Optronics # STL211RCB draw so little amperage (current) that you can wire them on your 20-foot trailer using 14-gauge (or heavier) wiring. We offer 10-gauge wire # 10-1-1 by the foot. You will want to use Right Angle 3-Wire Pigtail plugs # A47PB since this is the connector used for these lights. We also offer a mounting bracket # BK70BB and grommet # a70gb that are used together for a surface mount installation.

  • Do Trailer Reverse Lights Require Two or Three Wires to be Powered
    Reverse lights like the part # STL211RCB only need power and ground to function. You would not need three wires ran to the light assembly. Power would need to come from the reverse light circuit of the tow vehicle but you can ground the lights to the trailer frame or using wire to run back to ground of the trailer wiring. The version of the light I would recommend instead though is the part # BUL10CB since this is just a reverse light. For pigtail harnesses you'd want either the # A45CB...

  • Recessed Trailer Tail Light For 6-1/2" Oval With Clear Lens For Stop, Tail, Turn and Backup Lights
    The Fusion LED Trailer Tail Light # STL211RCB is a recessed light that is nearly identical to the GloLight LED Trailer Tail Light # STL1211RCFHPG. With the recessed light # STL211RCB you will need the PVC Grommet # a70gb to fit the recessed hole or Trailer Light Mounting Bracket # BK70BB. The recessed light and flush mount light use the same connectors. We do have the 3-Wire Pigtail # A45PB for the running light, turn signal/brake light and ground while the 2-Wire Pigtail # A45CB for...

  • Which is Brighter the LED Trailer Tail Light STL211RCB or STL211RB
    Since LED lights prefer clear lenses for maximum brightness the part # STL211RCB that has the clear lens and red diodes would be brighter than the # STL211RB. If you check out the picture I attached you can see how the diodes of the # STL211RCB are noticeably brighter. You can also see how the side diodes are the same intensity in either picture so you know the difference is due to the lens.

  • Trailer Tail Light for 2005 Fleetwood Gearbox Toy Hauler with Recessed Lights
    For your 2005 Fleetwood Gearbox Toy Hauler, the best way to find replacement lights is based on dimensions. The DOT number you gave is simply stating the light has passed the requirements to be on your trailer but doesn't give enough information. The attached article helps with that information if you are interested.

  • Plugs Needed for the Fusion LED Trailer Tail Light # STL211RCB
    At first I thought that this light had 2 places for the 3 terminal plugs but if you check out the attached picture of the Fusion LED Trailer Tail Light # STL211RCB you can see that one plug has 3 prongs (for tail light functions) and one plug has 2 prongs (for reverse light function). If you are just needing standard plugs then you would use part # A45CB for the 2 prongs and part # A45PB for the 3 prongs. These are also available at right angles with parts # A49PB and # A47PB respectively.

  • Recommended Trailer Light That Provides Plenty Of Light When Backing Up
    The trailer light I recommend for you is the Optronics, part # STL211RCB. This is an LED light that has 4-functions, stop, tail, turn, and backup. With the 16 LED diodes it will give you plenty of light you need when backing up. This light does measure 6-7/16 inches x 2-5/16 inches and is 1-1/2 inches deep. It does require the # A70GB grommet for mounting and if you do not want to cut holes in your trailer frame it can be surface mounted with the # BK70BB mounting bracket. We do not have...

  • Replacement Trailer Lights That Are Recessed Ovals With Grommet
    We don't have any lights in that specific size. The closest we have are the LED Trailer Tail Light - Stop, Tail, Turn, Backup - Submersible - 16 Diodes - Oval - Clear Lens # STL211RCB that measure 6-7/16" long x 2-5/16" tall x 1-1/2" deep. These install with the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB which should account for the measurement differences you mentioned. Other options are the LED Trailer Tail Light - Stop, Tail, Turn, Backup - Submersible - 16 Diodes - Oval...

  • Is There a Light Comparable to the GloLight LED Backup Light Without the Black Bezel
    I have a solution for you, but the GloLight LED Backup Light # BUL111CFPG does not have a comparable light that has a chrome bezel. I would instead recommend looking at either the Fusion LED Trailer Tail Light # STL211RCB and the chrome bezel # A211CB1 which can be combined for the look you're seeking.

  • Does the Optronics Light Guide LED Truck/Trailer Light Carry Stop/Turn/Tail/Backup Light Functions
    The Light Guide LED Truck/Trailer Light # BUL602CRB carries the tail and backup functions for trailer lighting but it doesn't have provisions for the stop and turn functions. For that you would need the Optronics light part # STL211RB or part # STL211RCB depending on what style you are looking for. These carry the stop/turn/tail/backup functions, have the exact same dimensions as the light you referenced, are submersible, and have the option for a recessed mount when used with the grommet...

  • Is the GloLight LED Trailer Tail Light Offered in Surface Mount
    The GloLight LED Trailer Tail Light part # STL1211RCFHPG is a surface mount light which means the flange mounts directly to the surface. The Fusion LED Trailer Tail Light part # STL211RCB is a similar light offered with recessed mount if that's what you're looking for.
