Optronics STL23 Series Miro Flex 4 Inch Round Sealed LED Tail Light Diagram

What Wiring Do I Need?

Optronics PL-3 Connection

This light has a standard 3-prong plug that connects to your vehicle or trailer with a PL-3 pigtail adapter. Pick up the right-angle pigtail (A47PB - sold separately) or the straight pigtail (A45PB - sold separately) if you don't have one already.


How to Mount Trailer Light

This light installs in a grommet (A45GB - sold separately) and requires cutting a hole into your trailer if it doesn't have one already.


If you'd rather not cut a hole in your trailer, you can use an optional mounting bracket (BK45BB - sold separately) instead. You will still need the A45GB grommet.

  • Bright LED Trailer Taillight Recommendation for Replacing 4 inch Trailer Light
    The Optronics LED Trailer Tail Light # STL55RB is going to the brightest option we have and will work great for your application. Each of these has 21 diodes in it which means it will put out quite a bit of light. The people behind you will have no problem seeing them! You'll also need the grommet part # A45GB to install the light as well as the pigtail part # A45PB. The mentioned light does not have reflectors but is very bright, the next brightest option that does have reflectors is...

  • Is the Optronics 21 Diode LED Trailer Taillight the Brightest
    Since Optronics does not share information such as lumens, determining the brightness can be difficult to determine. Although not always the case, typically more diodes indicates that the light will be brighter. The # STL23RB Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 21 Diodes - Round - Red Lens still has the most at 21 diodes which will make it one of, if not the most, bright red 4" stop, tail, turn lights. The only other 4" red light with as many diodes is...

  • 2 and 4 Inch Diameter Trailer Lights, Grommets, and Harnesses
    I will be happy to help and give you some options. For 2 inch diameter red lights we have several options: # MC53RB (use grommet # A54GB and harness # A46PB) # MCL50RB (use grommet # A54GB and harness # A46PB) # MCL55RB (use grommet # A54GB and harness # A46PB) # MCL55R1224B (use grommet # A54GB and harness # A46PB) All in one option # MCL-50CRK # MCL155RB (use grommet # A54GB and harness # A46PB) For 2 inch diameter amber lights we also have several options: # MC53AB (use grommet #...

  • Pig Tail Wiring with Load Resistor for Optronics LED Trailer Stop/Turn/Tail Light
    For Optronics trailer light # STL23RB you can use wiring harness # ALEDRST1B. This harness comes with a load resistor built in to prevent hyper flashing. Hyper flashing is more common when putting LED lights on vehicles and not normally and issue on trailers.

  • Hole Size Information Needed for Mounting Trailer Light Grommet A45GB
    It doesn't really have a wall thickness requirement. As long as the hole is 4-1/2 inch in diameter this will fit and work well. It is compatible with a light like # STL23RB. You will also need a wiring harness like # A47PB.

  • Are there Replacement Tail Lights for a 1982 Scamp Trailer
    In order to determine which replacement lights will fit your 1982 Scamp trailer, you will need to find the manufacturer and model number of the light assembly. This could involve removal of the assembly. If you see numbers on the lens, those are not the correct numbers. If you cannot find any manufacturer/model number information, you will need to measure the diameter of your existing tail lights and any other dimension that you can. You will also need to determine how they mount to the...

  • Can the 4 inch Rubber Grommet # A45GB be used in a 4-3/4 inch Mounting Location
    I do have a solution for you, since the hole that you are placing the grommet in is 4.75 inches, the grommet that you referenced, the Optronics # A45GB, might push through that mounting hole since the overall diameter is 5-3/8. Depending on your exact mounting location you might be able to use the # BK45BB to install on your light mounting location then use the 4 inch grommet # A45GB to hold a 4 inch light. I am not sure if this will work for your application but you might also be able...

  • Troubleshooting Rear Running Lights on Re-Wired Utility Trailer
    In standard trailer wiring all clearance lights and running lights operate from the same circuit. This means that if some of the lights are working but a few do not, then those non-functioning lights may have a ground issue or other wiring problem isolated just to them. Different lights can use different ways of grounding. For example, if your side clearance lights that do work use a wired ground, but the rear lights use the light mounting studs or posts to make the ground then it is possible...

  • Recommended 4 5/16" Clear Lens Light For Utility Box
    I may have an option but we do not have a matching white/clear lens light like the 4 5/16" Miro-Flex LED Trailer Tail Light # STL23RB you mentioned. The closest option we have is the ONE LED Backup Light # BUL003CB which is 4 5/16" and offers a water proof design with a clear lens and a single white LED diode. You will also need the 2-wire Connector # A49PB and Mounting Grommet # A45GB. I included a video of the ONE LED # BUL003CB for you to take a look at.

  • What Size Hole is Required for Installing Black Rubber Trailer Light Grommet # A45GB
    We have actually had this question before and we determined that the Black Rubber Grommet, # A45GB, mounts in a 4 1/2 inch diameter hole. It is compatible with a light like # STL23RB. You will also need a wiring harness like # A47PB.

  • Best Way to Install a Recessed 4 Inch Round Tail Light on a Trailer
    The best and easiest way to install a round 4" tail light like the Miro-Flex LED Trailer Stop/Turn/Tail Light part # STL23RB on a trailer would be to first clean the edges of the holes (no sharp metal) and then spray some soapy water on the gourmet while slipping it into place being careful not to tear the rubber. Once the grommet is in place you will then what to run the pigtail harness though the hole and plug it into the back of the light. Then you can then insert the tail light into...

  • How to Fix Motorhomes Hyperflashing after Installing LED Taillights
    Your motorhome must have a bulb out sensor. Becasue LED's draw so much less power than incandescents, the bulb-out sensor thinks the bulb is out and causes the circuit to hyperflash. You'll need to install a load resistor like # ALEDRST2B on each lamp. The resistor would plug inline between your existing PL3 plug and the lamp for a plug and play installation. This assumes you're using the # STL23RB lamp you referenced. If you're using a different lamp, you'd use the # DI34ZR and wire it...

  • 4-Inch Round White LED Work Light to Fit Rubber Grommet A45GB
    Optronics round light grommet # A45GB fits a 4-1/2-inch cutout and accepts a 4-inch round light such as # BUL43CB. This round white LED-type work light features 10 super diodes for bright high-efficiency lighting. This light is intended as a work light; it is not certified for use as a backup light. For a 2-wire pigtail lead you can use part # A45CB. Thanks to the high-efficiency of this LED light you can use multiple lights without causing the same power draw demanded by incandescent types.

  • LED Replacement Light Recommendation For Bargman 68 Round 4-1/2 Inch Trailer Lights
    We have four different round LED stop, turn and tail lights that will fit in the 4-1/2 inch diameter holes in your rear bumper. You could use the Optronics light, # STL23RB, # STL43RB, # STL53RCB or # STL23CCRB. These are 4 inch round lights, but they require a rubber grommet, # A45GB, that allows 4 inch round lights to flush mount in a 4-1/2 inch cutout. Lights # STL43RB and # STL53RCB are sealed, submersible lights if you are adding these lights to a boat trailer. All of these lights...

  • Black Rubber Grommet for 4 inch Round Trailer Lights A45GB Mounts in a 4-1/2 inch Diameter Hole
    The Black Rubber Grommet for 4 inch Round Trailer Lights, part # A45GB, mounts in a 4 1/2 inch diameter hole.

The light, grommet, part # A45GB,wiring, part # A45PB, and wiring, part # A47PB, are all sold separately.

  • How to Fix Rapid Flashing Blinkers on a 2004 Chevrolet Express After Switching to LED Lights
    I don't know how the lights affect the cruise control feature on your 2004 Chevy Express van; the two seem unrelated unless they are on the same fuse. But I can explain what is going on with the flashing lights. On some vehicles, if you switch to LED lights it sort of confuses the electrical system on the vehicle because LED lights draw much less power than incandescent lights. The vehicle basically behaves as if the bulb was burned out by rapidly flashing. This is called hyper flash...

  • What is the Melting Point of Trailer Light Rubber Grommet A45GB
    The type and composition of rubber is going to determine its melting point. Rubber grommet # A45GB is a lower grade than tires so it is on the lower end of the scale. Rubber components can start to melt at 160 to 356 degrees Fahrenheit. The grommet, being at the lower end, is likely in the 160 to 200 degree range but its melting point has never been officially tested. The lights this grommet is designed for are not made for high temperature applications which is why it is on the lower end...

  • Functions of Optronics 12 Diode Miro-Flex Tail Light # STL23RB
    The Optronics 12 Diode Miro-Flex LED Trailer Stop/Turn/Tail Light you referenced, part # STL23RB is a three function lamp. The # A47PB right angle pigtail, which is sold separately, has a white ground wire, a red wire that carries the brake and directional signal and a black wire that serves as the running light circuit. If the vehicle headlights were turned on, the lamp would be lit. Applying the brakes would make the lamp brighter. The lamp has several mounting options. It can be...
