Optronics STL79 Series Streamline Sealed LED Combination 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.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.


  • Overall dimensions: 17" long x 1-3/8" wide x 1" thick
  • Distance between mounting holes (center on center): 16-1/8"
  • Diodes: 11
  • Power draw at 12.8V:
    • Stop/turn: 0.35 amps
    • Tail: 0.022 amps
  • Lifetime warranty on LEDs

Video Transcript for Optronics Trailer Lights - Tail Lights - STL89RCB Review

Today we'll be reviewing part number STL89RCB, this is the Optronics Sealed Streamline LED Trailer light. It's going to be a red light strip, it's going to function as stop, turn and taillights. It's going to feature a sealed waterproof housing and lens unit. It's going to be corrosion resistant, it's also going to feature 11 super LEDs for exceptional brightness and performance. Again, it's going to feature that crystal clear polycarbonate lens, it's sonically sealed to the housing to provide durability and a waterproof seal to protect the LEDs inside. If we take a measurement, the distance between the two mount holes we have one right here and one right here, center on center, those are going to give us a measurement of 16 and 1/8 of an inch. The wiring design is going to contain lead wires and a ground wire to mount to all surfaces.

You're going to have your ground connection, you're going to have your red wire and your black wire for your power and your tail and brake functions. If we take a look at the overall dimensions, measuring the overall length that's going to give us a measurement of 17 inches. It's going to give us a width of 1 and 3/8 of an inch and then a depth of right at 1 inch. When it comes to the light draw, it's going to draw 0.342 amps and 0.22 amps at 12.8 volts. What we're going to do now is we're going to go ahead and hook it up to our external power source just to give you an idea of what the light looks like when it's fully lite up and has power running to it. We'll make our ground connection and then we'll go ahead and make the other two wire connectors to the power source. We'll go ahead and turn off our overhead lights, turn on our power source and then you can see that we have the bright taillight functions and then if we hit our brakes it's going to brighten up even more. It's also going to act as our turn signal.

That clear lens allows a lot of that red lights come through, providing a nice strong signal. That's going to do it for today's review of part number STL89RCB. This is the Optronics Sealed Streamline LED Trailer Light. .

This product was just as ordered. Service was great and I'd buy from them again. 525648


Great product and came in fairly quick. 514110


Yes, the STL89RCB is impressive especially at night. It was a badly needed upgrade to my existing brake/tail lights which have been partially blocked by new bike rack. I gave it 4 stars since the pigtails from the light were not consistent: on one light, the red wire was the tail/running light but the other used the black wire. Good thing to check both lights before soldering. 505346

Still working great

The lights worked well for my Casita trailer since i have bikes on the back blocking the primary lights. They are quite visible from other drivers.
