This Miro-Flex LED trailer light brings strong, even illumination with 14 diodes that shine through an amber lens. It draws only 0.301 amps for stop and turn and just 0.020 amps for tail light use, giving you crisp brightness without loading down your wiring. The faceted reflector design increases light output while keeping things energy-efficient and maintenance-free compared to incandescent bulbs.
The sonically sealed polycarbonate lens and housing form one waterproof piece that keeps out moisture and dirt. Whether you’re on wet roads or backing a boat into the water, this sealed design prevents corrosion and protects the internal LEDs so the light stays reliable over time.
Mounting is straightforward with a recessed setup that uses a grommet (A33GB – sold separately). The light accepts an industry-standard PL-3 plug such as the A45PB or A47PB (sold separately), so wiring is quick and compatible with most existing trailer harnesses. You get a tight fit and clean, professional look without custom fabrication.
Built with an all-weather molded plastic housing, this rectangular unit measures 5-5/16" long by 3-7/16" tall by 2-5/16" thick. The polycarbonate lens resists impact and UV damage, standing up to rough use while keeping the LEDs protected. With a lifetime warranty on the LEDs, it’s a dependable upgrade built to last.
This light meets all required lighting standards for road use, giving you peace of mind that your setup stays compliant while improving visibility for everyone on the road.

Today we're going to review part number STL35AB. This is the Optronics Miro-Flex, Waterproof, Rectangular, LED Trailer Parking and Turn Signal Light. This is an amber, rectangular light, serves two functions, turn and parking light function. This is a great replacement for incandescent lights. There's no bulbs to replace, no brittle L filaments to break. It does use the Miro-Flex technology. That combines a smooth lens.
If you look under the inside, it's a faceted reflector design. It's gives you a nice, smooth automotive appearance while maintaining the traditional footprint. It does increase the light output while using 90% less energy than incandescent bulbs. The LED light does draw less amps. This is a sealed, molded-plastic waterproof housing and a durable lens. It is corrosion resistant, uses 16 amber LEDs. To mount this, it does require a mounting grommet for flush mount and an industry-standard 3-prong plug for complete installation. I do want to show you those parts.
If you do have those parts already, you can use them. If you need to purchase them, we do sell those separately on our website. The are listed on the product page of this light as replacement parts or related parts. Here's the example of the rubber grommet, part number A33GB. Again, it's sold separately. Basically, your light would just pop it all the way in there for a nice, flush mount fit. The other recommended is the 3-prong plug.
I've 2 different ones. This one, the first one, is the straight 3-wire prong plug. It's part number A45CB. Basically, what you would do with this is just line the plugs up, go ahead and push it all the way in, and you can see the reason it's called a straight 3-prong plug is because the wires come straight out the back. Depending on your application, you can use that one. The other one would be if you need some more clearance.
They offer a right-angle, 3-prong plug. This is part number A49PB. The nice thing about that is when you get the pushed in there, you can see that the wires come out from the light at a right angle to give you some extra clearance. Depending on your application, you'd the choose the correct 3-prong plug that you would need. Let's go ahead an pull this one off. There we go. I'll give you a new dimensions on this. The length of this light from edge-to-edge is going to be right a 5-5/16. Again, the height from very edge to edge, bottom to top, is going to be right at 3-7/16. The depth of it, edge-to-edge right here, is going to be about 1-1/2", and on this end has the extra plastic housing around the plug, edge-to-edge is going to be right at about 2-5/16. This light is Department of Transportation approved. It does come with a lifetime warranty on the LEDs. What I'm going to do now is we're going to go ahead and use one of the plugs. I'm going to hook it up to a 12-volt power supply to give you an idea of the functions and how bright it is. Again, the 3-wire prong plug will have a white wire for the ground. It will have the red wire for the turn signal operation and the black wire for the parking light. We'll go ahead and hook those up. Now with them hooked up, I'm going to go ahead and turn off the overhead lights, go ahead and turn on the 12-volt power, and there you can see the parking light, now bright it is. Then the turn signal function, lights up a lot brighter for the turn signal function. We'll go ahead and turn off our power, turn back on our overhead lights, and that should do it for the review on part number STL35AB. This is the Optronics Miro-Flex, Waterproof, Rectangular, LED Trailer Parking and Turn Signal Light. .

Nice bright good looking lights used for turn signals on the front of a Samurai.I Recommend them!
This will be going on my 54' Chevy Hotrod. Turn signal and running lights for my custom grill. These look outstanding.
The light showed up well packaged and in a timely fashion. It's exactly what I was expecting. I wouldn't hesitate using etrailer again.
I have had great experience with this company. Shipments are fast and if there are any issues you get called. Thank you etrailer+
Lights look good,won't be installed till trailer is out of storage...
*Only issue I had was I wished shipper had packaged lights in protection bubble wrap, light lenses got scratched up in the box with other loose items:/
Products I bought from Etrailer were shipped quickly. Was replacing existing lighting and went to the led lighting. Description of part was accurate. Good choice for me. Price was better than I could get locally. Good company to do business with.
They work and look great,, only issue was it took 8 days to arrive,, installed on my bus im assigned only i drive that bus other drivers noticing
Etrailer STL22ab: Another great product from Optronics through ETRAILER.COM
The technology of the Miro-Flex is an amazing upgrade from the previous generation of LED lights. Even in the dark garage, not connected to any power source, I set this light, and a 1st generation 6inch LED light on the table. Turned off the lights and shined a flashlight over both of them. The STL22ab reflected light from all of the 16 individually prisms. It was amazing, the other LED did not. This light is BRIGHT, solid construction and arrived from ETRAILER.COM quickly packaged in a box to protect it. Will be ordering 4 RED ones to replace my other older LEDs.
Great BUY!
The lights look and work great! Super customer support from George too! What a nice change from my old bulb lights.
Here are some day and night pics. I have a short vid of a turn light blinking, but the site won't let me upload vids.
Great price and fast delivery
Very nice customer services ! Great pro ducts!
I have received the product and am very happy to say that the product is going to work for the application we needed it for.
However we did have a question on if you could provide part numbers for us.
We want to get the pig tail and the grommet for the lights we just purchased for us.
Could you provide part numbers so we could get those ordered?
These lights are of very good quality and are really bright. I use them on an early 70's Bronco for the front turn signals. Day or night, they are distinct and unique and best of all, . Definitely visibly on during the night AND the day (this can be seen in the photo taken on a Snow day, bright, while half way out of my garage). Great price for a great product
