Features to know about

Brighter, Longer-Lasting Visibility: 24V LED Stop/Turn/Tail Light

This round Miro-Flex LED light shines bright and clear, making your trailer easy to see day or night. It’s built with 12 red LEDs that glow for tail lights, brighten for brakes, and flash for turns—all in one 4-5/16" diameter housing. At just 0.171 amps for stop/turn and 0.061 amps for tail at 24V, it gives you strong, efficient output without the heat or power draw of old incandescent bulbs. The LEDs are long-lasting, so once you install it, you can forget about burnt-out filaments.

Worrying About Water Damage: Fully Waterproof and Submersible Build

If your trailer ever deals with rain, splash, or full dunking, this light handles it. The polycarbonate housing and lens are completely sealed against moisture, so it’s safe for boat trailers or any setup that sees harsh conditions. That waterproof design means no fogging, no corrosion inside the lens—just consistent light every time you hit the brakes or turn signal.

Needing a Durable Light that Mounts Cleanly: Flush Recessed Mounting Option

This light installs flush with a grommet (A45GB – sold separately) for a clean, tucked-in fit. It can mount in any 360° position and works with a standard PL-3 connector for easy hookup using a 3-prong plug such as the A45PB or A47PB (sold separately). If cutting into a panel isn’t an option, there’s an optional bracket (BK45BB – sold separately) to surface mount it instead. Either way, the setup stays solid and looks neat.

Built-In Reflector for Extra Safety: DOT-Compliant Design

The built-in reflector adds another layer of visibility without needing a separate reflector plate. It catches light from other drivers and makes your trailer easier to spot from any angle. And because it’s DOT compliant, you know it meets the standards for road use and safety lighting.

Reliable Lighting You Can Trust: Lifetime LED Warranty

Every diode inside this Optronics Miro-Flex LED Trailer Light is backed by a lifetime warranty. That means you get dependable lighting mile after mile—no flicker, no fuss, no worries about replacing bulbs again.

Great replacements for my GMC 3500 flatbed's lights

Did this improvement on my Tab trailer in under two hours.
Great lights
Excellent place etrailer good advise thanks Matthew

Awesome tail lights



by:

These lights are super bright as you might expect with 12 led's each. The quality of the materials is very good. I started out buying two of these and they looked so good I ordered two more and replaced the back up lights with the last two.



by:

Great lights very bright and perfect for my complete clear lens trailer light set up



by:

Good design and materials. Bright light, and easy fit into accessory mounting parts. As a single middle third light, it functions as a brake, running and directional lights. Perfect for a hitch mounted bicycle rack.



by:

Excellent replacement products for the bullet bass boat trailer. Upgraded all trailer lights to LED.



by:

I attached lights to my 34 Ford Coupe replica Streetrod golf cart. The original lights weren't bright enough. The Led lights fro etrailer were great and really bright. Wonderful service on all end talking on the phone and shipping items. Thanks for the friendly service and a great product.



by:

Love these LED trailer lights and now Love Etrailer!! Did a quick Google, found these guys, they had what I was looking for and at a great price. Their shipping was FAST, and I really liked the e-mails letting me know every little thing about my order and when it will arrive. Installed them the same day I got them. Installation was very easy and the lights were VERY bright. We had to bring the 3k pound trailer home today in 6" of snow. I felt great knowing the people behind me knew I was hitting the break, because you can see these break lights from a mile away!! Thanks Etrailer!!



by:

The light replaced the tail light on my golf cart perfectly.



by:

The order process was easy and met my full expectations. I would recommend etrailer for any trailer needs.



by:

Definitely a major upgrade from the single bulbs that finally went out on my old trailer. Simple as can be when it comes to install them. I did have to run additional ground wires to get to get lights to work when the parking lights are on. Could have been due to the fact my trailer is a tilt trailer? No big deal just a heads up if anyone else is having the same problem. Pictures shows them with parking lights on and brake lights. They're bright that's for sure!



by:

Perfect fit to replace a "Command Electronics #003-5400" sealed lamp (original from about 20 years ago); very nice bright LEDs!



by:

I installed these lights in a T@B teardrop camping trailer. The grommet would not work on this style trailer so I installed the lights using a silicone adhesive the same as the original Peterson lights. eTrailer delivered them in the same timely manner I have come to expect from them and the LEDs were easy to install. These lights are blindingly bright - simply amazing. I had rear lights with 1157 bulbs which I had upgraded to 2357 bulbs and equipped the tow vehicle with a powered converter but the light output was dim by today's standards. These lights are twice as bright on running lights and about 4 times brighter on the brake/turn signal elements. The thing we all fear when towing is being hit from behind by a driver that does not see our running, brake or turn signal lights in time. I know these lights will vastly improve the safety and visibility of our trailer. Thanks!



by:

They look good! And affordable too!

by:

Very satisfied



by:

Items are of good quality and arrived quickly. The correspondence from the retailer was good and I'll most likely purchase again



by:

Good light. Used in ElDorado National bus, which uses 24 volt lights. This was about the only place I could find them. Thanks!!!



by:

Excellent pricing much better than the dealer for the same thing. Good customer service



by:

Ordering was easy, found the info I needed on these lights on the etrailer site from a prior question someone else had asked. The tech info available on the etrailer website is the best.



by:

Fantastic Lights, will continue to order them. No confusion if they will run on 24v with the plain sticker on the back clearly labeling 12/24V. Different brand turn signal keeps getting water logged on same vehicle, this light has been rock solid! Thanks Jason V. for the 12v or 24v hint.



by:

These are good lights. Love (and require) that they run on 24 volts as well as 12. This is the only place I can find them, but they are a good price, with fast cheap shipping so I would get them here anyway. Thanks!



by:

purchased four lights to upgrade from the old bulb style. They have performed well without trouble except for one that has lost a couple of led lights - thought they should have lasted better than that but way ahead of what I was using.



by:

Received late last evening and everything in the package looks to be what we ordered. They will not be installed for most of 6 months as we are wintering in Florida. Service was very good. Pleased. Lights look good. Thank you.

  • Recommended LED Trailer Tail Lights for 24 Volt Military Truck
    The trailer tail light I recommend that is compatible with a 24 volt electrical system is the Miro-Flex LED Trailer Tail Light part # STL23R24B which has stop, turn, and tail signals. If you would like to add reverse lights as well then you can use the LED Backup Light part # BUL11CM24B. We do not have an all in one set of trailer lights that are compatible with a 24 volt electrical system. Unfortunately, most of our trailer lights are only compatible with a 12 volt electrical system like...

  • Installing Trailer Wiring on a 24V System of a Military Hummer --1987 M998 hmmwv
    I've attached an article as well as a photo to assist, but you will need to add a step down converter between your light functions, and add a 24V relay between the cold side of your brake light switch for your brake controller if you will be using electric brakes on the trailer. There isn't an easy wiring harness with this converter already installed, so I recommend you use the Curt Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 60" Wire Lead # C58044 (you will need to get...

It measures 4 inches in diameter and 1-15/16 inches deep. To install this light, you would also need Rubber Grommet for 4 inch Round Trailer Tail Lights, # A45GB, and Straight 3-Wire Pigtail for Sealed Trailer Stop, Turn and Tail Lights, # A45PB.

  • LED Taillight Recommendation for a 1968 Heilite Trailer
    We have exactly what you need, but the # 294-0967 is for tow bar lighting for vehicles that are getting flat towed so it wouldn't be a good choice for you. For a similar light to what you have on your trailer that would be LED I would recommend the # STL23R24B. For a wiring harness you would want the # A45PB. For a mounting flange you would want the # A45BB.

  • Converting a Trailer with 12 volt Lights to 24 volt Lights for Compatibility with a Euro Spec Truck
    I think your only real option would be to replace the trailer lights on your trailer with lights that are compatible with 24 volt systems since there isn't an adapter available that we offer that would work for converting your 24 volt system to work with a 12 volt lighting system. Right now, we have a few select 24 volt tail lights. We have # STL23R24B and # STL90R24B. For turn/marker lights we have # STL90A24B and # STL23A24B. And for reverse lights we have # BUL23C24B.

  • Can a Bus with a 24 Volt Electrical System Tow a Trailer and Car with 12 Volt Electrical Systems
    On the trailer it will be easy because you can add 24 volt lights such as # STL23R24B and # MCL66A24B just to name a few. But to flat tow a vehicle that is a different story. You would need to obtain a voltage reducer device and put one on each circuit ahead of the trailer connector so that it is 12 volts on the output side. We do not carry these devices and from what I know they can be expensive. If you go this route then the trailer would not have to have 24 volt lights.

  • Recommendation for 24 Volt Trailer Lights
    We do have some lights that are designed to work on a 24 volt system but none that are available in a kit. I recommend using light # STL23R24B. There are a few ways to mount this light. You can use a grommet and flush mount it using # A45GB. Or you can surface mount it with a bracket, # BK45BB. You will also use a wiring harness, # A47PB.

  • How to Get LED Lamp # STL23R24B into # A45GB Grommet
    I went out to the warehouse and pulled both the lamp you mentioned, part # STL23R24B and the grommet, # A45GB. As you can see in the short video we produced for you, the parts do indeed fit together. The fit is kind of tight, and you will need to start the lamp into the grommet and then work your way around stretching the grommet into place around the lamp. Soaking the grommet in hot water for a few minutes will soften it a bit and make it more pliable. You can also try lubricating the...

  • Trailer Lights for 12 Volt and 24 Volt Systems on a 1994 Mercedes G Wagon and Honda CR-V
    Some trailer lights can be used on either a 12 volt or 24 volt system, but # STL16RB is not one of them. You could use # STL23R24B with harness # A47PB, grommet # A45GB, bracket # BK45BB for a 24/12 volt system and it would work with both vehicles.

The width of the assembly behind the lens is 4-1/8 inches. The overall diameter is 4-5/16 inches. I believe this is the measurement you are looking for. For a rubber grommet to install this light you would want the part # A45GB. For a pigtail harness you would want the A47PB.

  • Can the Optronics Sealed, Miro-Flex Trailer Clearance Trailer Light Be Used as a Brake Light
    The 3 diodes in the Miro-flex light, # MCL51RB, would not make a very good brake light. They would not be as bright as the regular brake lights already on the trailer. You would need a light designed to function in whole or in part as a brake light such as # STL23R24B. With this light you would also need a wiring harness, # A47PB. To mount it you could use mounting bracket, # BK45BB and grommet # A45GB. You could also flush mount it using the mounting flange # A45BB.

It measures 4 inches in diameter and 1-15/16 inches deep.

    The Sealed, 4 inch Round Trailer Stop, Turn and Tail Light, part # ST45RB is designed to work with a 12 V system. I have attached a product review video for this light you can check out. This light accepts the 3-prong connector like part # A45PB. The grommet used with this light is part # A45GB and is sold separately. For a 4 inch light that is designed for a 24 volt system I recommend part # STL23R24B.
