Optronics STL55 Series High Count LED Tail Light Dimensions

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 housing or a grommet (A45GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Video Transcript for Optronics Trailer Lights - Tail Lights - STL55RB Review

Today we'll be reviewing part number STL55RB. This is the sealed 4" round, red LED light from Optronics. The red, 4" round, stop, turn-signal and taillight is going to be a great replacement for incandescent lights. You don't have to worry about the bulbs and you don't have to worry about the brittle filaments. It's going to feature a sealed housing and lens unit. This is a recessed grommet mount but the grommet is going to be sold separately.

You can find that right here at etrailer.com with part number A45GB. It's also going to accept your industry's standard 3-prong plug; that's going to be sold separately as well. If you need a right angle plug, you can use part number A47PB or a straight plug like I'll be using on our demonstration today with part number A45PB. Again, those can be found right here at etrailer.com. It's going to feature 21 Red LEDs. Taking a look at the overall dimensions, it's going to give us a diameter, measuring from edge to edge, of 4-1/4" with a depth and this depth is including the plug of about 1-7/8" and then not including the plug is only about 3/4". The LED light draws 0.30/0.10 amps at 12 volts and it is Department of Transportation approved. We're going to go and hook it up to our external power source that way you can see what it looks like with power running to it.

All we need to do is make the connection with the 3-prong plug. It's going to stick that and the connection points and then I'll just push it in. You can see here that it's going to send out a nice, consistent LED signal. This is going to be the taillight function and it's going to illuminate whenever we hit our brakes. It brightens up quite a bit.

It's going to be the same function when we apply the turn signal as well. That's going to do it for today's review of part number STL55RB. This is the sealed 4" round, red LED light from Optronics. .

These are fantastic. I really like the brightness, how they install (quick connector plug) and the fact that they are sealed. They mount in gasket that also provides shock protection and a good tight fitting. Had no issues with either one to date. Would buy these for all future trailers. Looks great, works great. 455182

Product was exactly what I was looking for as I was replacing a 4" taillight on a truck camper. Since the 4" lights are fairly standard, I was able to quickly replace the bad ones. Staff went out of their way to offer me a more effective shipping solution that what I had chosen on my own including taking the time to personally contact me. My first purchase with them, very satisfied. 132711

Ask the Experts about this Optronics Trailer Lights
Do you have a question about this Trailer Light?


  • Replacement Tail Light For Forest River Georgetown XL RV
  • I'd be happy to assist you. It sounds like you need the Sealed, Flush Mount Tall Rectangle LED Trailer Stop, Turn and Tail Light, Grommet and Plug, 12 Diode # STL34RB but most of the pictures I see have round tail lights like the Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB. If this is not the correct part, then send me a photo with the measurements of the light and we will get you what you need. The numbers and letters that are actually printed on the light...

  • Recommended Trailer Tail Lights for 4.25 Inch Opening
  • The LED Trailer Tail Light # STL42RMB has screw mounting holes that are 4-1/4 inches on center. The smallest hole this light will fit is 4 inches. You will have difficulty mounting this light as your opening matches the mounting hole locations so you won't get proper hold. You may want to use the Rubber Grommet for 4" Round Trailer Tail Lights # A45GB along with the # STL55RB which won't use any screws to mount. You will also want the 3 wire pigtail # A45PB.

  • Recommended LED Replacement Lights for 2005 Damon Daybreak Motorhome with Load Resistors
  • The Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB will work great on your motorhome. You will simply need to use the wiring pigtail # A47PB for each light. You will simply need the butt connectors # DW05744-5. On some vehicles, when switching to LED lights, there is a load resistor needed to prevent hyperflashing but this is not always needed. If you do end up needing a load resistor, I recommend the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 #...

  • Replacement Tail Light for 2009 Ranger Boat Trailer
  • Sometimes it is possible to replace a broken trailer light with one that uses a different type of installation but since we offer a very wide range of lights you may very well be able to find an exact OEM-style replacement. It sounds like you have a light like # STL42RB which has a 3-hole mounting flange. I linked our main page for trailer tail lights of all shapes and sizes. On the page you can simply click on the filters for light shape, light type (LED or standard bulb), lens color,...

  • Recommended Grommet for Optronics 4 Inch Round LED Light # STL55RB
  • Both the Rubber Grommet # A45GB and the Notched Rubber Grommet # A45GNB that you referenced will fit and work well with the Optronics 4" Round LED Light # STL55RB. The only difference between the two grommets, as you mentioned, is the notched cut out in the lower portion of the unit. This is not necessary for wiring or fitment, but it will allow for a bit of an easier install.

  • Mounting of Optronics 4 Inch Round Tail Light
  • The Optronics Tail Light # STL43RBX does not need a bracket for mounting. It has a built in flange and includes a rubber grommet. A similar light, # STL55RB, uses a stainless steel mounting flange # A45SB. Both lights can be connected using a 3-wire pigtail, # A45PB, or # A47PB for a right angle.

  • 4 Inch Round Trailer Tail Light Cutout Size
  • The closest to 4 inch round lights we have is the Optronics LED Trailer Utility Light # BUL43CB or Trailer tail Light # STL55RB which are actually 4-5/16" diameter x 1-15/16" thick. These are designed to fit the Rubber Grommet for 4" Round Trailer Lights - PVC # A45GB which requires a 4-1/2 inch diameter cutout. You will also need wiring pigtail # A47PB. If you are interested in the Optronics Trailer Tail Light - Stop, Turn, Tail - Incandescent - Round - Red Lens # ST40RB you asked...

  • Replacement 4 Inch Reverse Lights to Replace Truck Lite Stop Turn Lights
  • If the cut out diameter of your vehicle is 4-1/2 inches then you can install the part # STL55RB in place of what you have with the grommet part # A45GB. For a similar clear version of this light you would want the # BUL43CB.

  • Replacement 4 Inch Round Tail Lights With Stop/Turn/Tail Functions
  • We have many 4 inch round tail light options like the Peterson Round Trailer Tail Light, 2 Stud Mounting, Right Hand # 431800. We also have LED options like Optronics Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB. I've linked the page to our 4 inch round tail light options for you that have the stop/turn/tail functions.

  • 2 inch and 4 inch Diameter Recess Mount LED Clearance Light Recommedation
  • For the 2 inch light you would want the part # MCL55RB with the grommet part # A54GB and pigtail part # A46PB. For 4 inch we have the part # STL55RB. You would need the grommet part # A45GB and the same pigtail # A54GB. I wish we had a 3 inch option, but you may be able to enlarge the 3 inch holes to match the 4 inch ones.

  • 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...
