Optronics STL22 Series Miro-Flex Oval Sealed 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.

Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a grommet (A70GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Fit like a glove. Just what I needed. It replaced a tailight on a 2001 trailer.


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!


Product was exactly what I was looking for, Prompt shipping got all products in time for our plan on traveling and everything fit as it should will definatly purchase more from them as needed


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


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!!


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.


The lights were great. Instigation was very easy. The service and delivery time was excellent. I will adding more LED lights to my trailer and I will be buying them here! Thank you to your entire staff!


Ordered led lights to replace all the lighting on my triaxle trailer. Parts arrived sooner than expected and were a terrific upgrade. I had an issue with one taillight. The item was replaced at no charge, no hassle, no questions asked. Fantastic customer service.


They are still working great after 1 ye ar!!


Bright lights. Great upgrade from the incandescent. Very easy to remove old ones and install these on my triton snowmobile trailer.


Sirs: I have a ten-foot enclosed motorcycle trailer that I purchased new in 2010. Recently, I noticed the existing taillights were working -- but were far from being safe. I assumed that I had a wiring problem and that I might have to take the trailer somewhere and have the wiring harness checked and/or replaced. Fortunately, I looked at several of the videos on your web site and decided that I would replace the existing taillights before committing to a re-wire job. I ordered a pair of STL22RB 12 diode trailer lights and a pair of a70gb gaskets. These items arrived in the mail yesterday, and I installed them this morning. Problem solved! The new LED lights work quite well, and the installation took less than five minutes. I have some light bulbs in the house that take longer to replace than did these taillights. Thanks, guys, the videos that I looked at on the web site convinced me that I could do the job simply, quickly, and safely. Piece of cake!!! Now, I may change out all the old marker lights with new LED lights. Thanks, again. Lou C.

These LED lights are still working as well as the day day they were installed. Great product. Great video info provided by

Awesome tail lights

Awesome tail lights !!!!
Samuel - 05/21/2017


Perfect, just what I ordered!!!


Nice and bright. Drivers will be able to see these lights when my taillights are obscured by bicycles.


One was fine, the other is a different light. I ordered 2 of this model and got one and a 72RB plus it looks used, the lens is all scratched

Wow, I am sorry that you received the wrong product. Customer Service will take care of this for you.
-- Etrailer Expert Sierra K - 08/24/2021


These lights were an exact replacement for the original incandescent lights in my car trailer. They are very bright, and traffic behind me actually pays attention when I turn my signal on now. They are a much needed improvement over stock. Juanita was also very helpful in verifying that I had the right connector for them. Very prompt shipping too, as I had them in 3 days after I ordered them.

The lights work as good as new. They are a great replacement over stock tail lights.
Don G - 10/21/2015


they are nice and bright sorry no picture of them in action video would not load to site

Ahhhh! Is all I hear from those behind me cause they are so bright and thats what you need on the back of your motorcycle. Very pleased!!!
Randall - 07/30/2017


What do y'all want a follow up to? If i had a nickel for every item I've ordered off of ETrailer, I wouldn't have to work for a few months... I keep coming back because the prices are fair, shipping is free and fast, and ETrailer has everything I need.

I do wish you sold trailer kits though. Being a welder, I have built a few trailers in my free time and sold them for a small side business. Why isn't there an axle, fender, brakes, springs (shackles and all hardware) tires and wheels kit? It would be nice to not have to go and click and add to cart all the multitude of items I need to build a trailer individually. Just saying...


The lights are good and standard size, but they seem to have a slightly off plug receptical. I ordered 6 of them and all seemed to be the same. I had to bend my connectors with a pliers a little bit to get them plugged in.


Miro-Flex Trailer Tail Light - Stop, Tail, Turn - LED - Waterproof - 12 Diodes - Red Lens - STL22RB EXCELLENT LED if you are in the market for an oval shaped RED or AMBER LED light, this new technology by Optronics, Miro-Flex is amazing. Love these over the 1st generation of LED. Reflects light even without being on, is very bright, solid construction and looks cool. Using 4 on the back of the trailer, just getting the 1st one hooked up was bright!!! Purchased the 3 pigtail to plug into it, the female plug frame is solidly constructed. This is a great purchase. Also look at the other Optronics Miro-Flex lights. ETRAILER.COM delivered quickly in a solid packaging. Great job guys!


Awesome looking upgrade for older trail er...


very nice brake/tail lights, worked great as replacements for my boat trailer. Economical, bright, highly recommended.

still working great a year later, works much better than the last LED set different supplier that I put in. Highly recommended!
Kevin - 07/22/2014


Used these to replace stock lights on a 2010 Continental Cargo (Forest River) box trailer for our Boy Scout Troop. New lights snapped in perfectly and are much brighter, factory wiring harness had no issues. Would buy again if I need to, but with LED hopefully this is a non-issue.


I upgraded the lights on my kayak trailer from incandescent to LED after getting tired of replacing burned out bulbs on the old lights. The new STL22RB LED tail-stop-turn lights are great. I also installed the red and amber side marker lights MCL11RKB and MC11AKB and the are great too! The new tail lights are very bright when viewed from directly behind the vehicle (see picture), but they are less bright when viewed from an angle...I think that is normal with all LED lights. Everything was easy to install on my trailer with the BK70BB brackets and wiring harnesses. I will definitely recommend the lights and etrailer to my friends!


Working on 1982 tandem axle boat trailer replacing all lights to led.
etrailer is the only one I found online that gave the dimensions of their lights & as a plus videos of them. Super store they are on top of everything makes all other competitors look stupid . Thanks for everything because of your attention to detail all the lights & light grommets were a direct fit saving me lots of time not having to retro fit anything. ANCHOR'S UP !!!

See what our Experts say about this Optronics Trailer Lights

  • Troubleshooting Trailer Lights Not Functioning When Headlights are On
    It sounds like there is too much amperage being drawn on your trailer when the headlights are on and it is too much for the trailer so everything shuts off. This could be because of a bad ground somewhere. First thing I would do is check the grounds on the trailer for any loose wiring and corrosion and fix as necessary. If the grounds are good you might need to convert your trailer lights to LED lights so as to minimize the draw on the trailer light circuits. LED lights draw a fraction...

  • Troubleshooting Dim LED Trailer Lights after New Wiring and Light Assembly Installation
    The problem is either the power or the ground side of the wiring of the LED assemblies. First thing to do is check that 12 volts are making it to the trailer connector. You can use a circuit tester like our part # 3808. Next, trace the wiring back to the light assembly testing as you go with the circuit tester to make sure the voltage is making it to the light assemblies. Next, you need to make sure the ground wire of the light assemblies are connected to a clean, metal surface. If you...

  • What to Consider When Picking Out LED Trailer Lights
    I have a couple links for you to check out. First check out the link I attached that details all of the different lighting requirements for trailers based on overall size. Most likely you will just need to replace every light you currently have with an LED version, but it can't hurt for you to check out just in case. The second link I attached will take you to a page that has all of the LED trailer lights we offer. You will need to compare what you have on your trailer to what is listed...

  • What is the White Wire of a Trailer Taillight Wiring Harness For
    The white wires of your trailer lights are the ground wires. It sounds like your previous trailer lights grounded through the mounting hardware so because of that you would need to run the white wire of the new assemblies to either a clean metal surface that touches the trailer frame or back to the main ground for the trailer's wiring. The green would be right stop/turn and the yellow would be left stop turn. The brown is taillights.

  • How to Wire a Stop/Turn/Tail Trailer Light With Two Wires to a Trailer
    It sounds like you have a trailer taillight that grounds through the mounting hardware. Typically the red wire would run to the turn signal/stop light circuit and the black would run to the taillight circuit, and then the ground circuit would be complete through the mounting hardware.

  • Replacing 2-Wire Trailer Light with 3-Wire Trailer Light
    The white wire on your new trailer light assembly is indeed for ground. Your old tail light grounded through its mounting hardware so it didn't use a separate wire for this purpose. You just need to attach the white wire on the new light to a clean, bare metal surface on the trailer frame.

  • New LED Lights Do Not Work on Trailer with Same Connector
    The photo did not come through but are you sure that the pins inside the old connector matches the socket inside the new light? They could look very well the same and even plug into one another but that doesn't mean they are wired the same. I would find the pin inside the light that is supposed to receive power and then check to see if it is in fact receiving power using a circuit tester. There could also be a ground mixup. For example, the new light may ground though the hardware and the...

  • Troubleshooting Installation of LED Trailer Lights with Red, Black, and Yellow Wires
    If your LED has red, black, and yellow wires, then I recommend running jump wires from a battery to test functions before installation. It is likely the red wire will be the stop, the black wire is running light, and the yellow is possibly the turn signal. It sounds like this is a 3 wire light that may ground through mounting hardware. Without seeing the light, that is my initial thought since the wire colors are not standard. When you test functions on each wire, then you will know...

  • Troubleshooting Trailer Wiring that Stopped Working After LED Trailer Light Install
    Sounds like you have a short between the stop/turn circuits and the 12 volt accessory circuit which is putting voltage on the power wires for the lights at all times. Best option is to go over the wiring of the trailer looking for any obvious shorts like exposed wire etc. and fix as needed.

  • Recommended Replacement Tail Lights for 2013 Itasca Cambria Motorhome
    We don't have a database that tells us exactly what lights are on specific coaches, but I was able to find some photos and videos online that show a 2013 Itasca Cambria and it looks like they've got a fairly unique oval shaped tail light. With that said, it looks like they're LED lights, so you may be able to use something like the Miro-Flex LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 12 Diodes - Oval - Red Lens # STL22RB. These are recessed mounted lights that are 6-1/2"...

  • Is White Wire of Trailer Wiring Most Commonly the Ground Circuit
    For trailer wiring the white wire is almost always the ground wire circuit. Since trailer wiring gets redone periodically it's not uncommon for the colors of the wiring to get changed but in general white being ground is the most consistent. Then the brown would be most likely the running light circuit. I attached a link to a page that has trailer wiring diagrams for you to check out as well.

  • Optronics Trailer Lights # STL70RB and # LED Light Brightness
    I spoke with my contact at Optronics and was informed that the Lumen difference between part # STL70RB and part # STL22RB LED stop, turn and tail lights is not tested by Optronics. I was told that the more LED lights in the tail light the brighter the light will be. I have seen these lights on display and these lights are very bright especially as compared to incandescent lights.

  • Method of Bulb Replacement on Oval Red Grommet-Mount Trailer Taillight
    Usually a grommet-mount incandescent tail light will be pressure-fitted into the grommet and held there simply by friction from the rubber. If there are no visible screws to allow lens removal and no accessible portion of the light's rear surface then its almost a sure thing that you'll just need to carefully pop the light out of its grommet. Ideally you'll have a tool that is strong enough to flex the grommet material but not so hard that it can damage the lens or base. The light in your...

  • Switching from Incandescent to LED Trailer Lights
    If you're switching from incandescent lights to LED lights on your trailer, then because of the difference in power draw between the two lights you may need to add a resistor between the relay and the light. If you have issues like hyper flashing or voltage bleeding once you've installed the lights you can use a resistor similar to # ALEDRST1B behind each relay, but in front of the lights. This is in order to make sure that your new LED lights aren't overloaded and will function correctly...

The black wire is spliced into your running lights, or the lights that are turned on your vehicle when the headlight switch is on.
