Optronics STL603RB Light Guide LED Trailer 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.


PL-3 Wiring Connection

Optronics PL-3 Connection

This Light Guide light has a standard 3-prong plug as pictured above. A 3-prong pigtail (A45PB or A47PB - sold separately) is required to connect this light to your vehicle or trailer. You will also need a rubber grommet (A45GB - sold separately) to install your tail light. An optional mounting bracket is also available (BK45BB - sold separately) to make it easier to mount the light on your trailer.


Recessed-Mount Light

Recessed Grommet Mount Trailer Light Installation Diagram

Recessed-mount trailer lights install with a grommet, which is often sold separately. These lights extend past the trailer surface and require a hole for installation. If replacing a light, you can utilize the pre-existing hole. If installing a new light, you will need to cut a hole or use a mounting bracket (sold separately) to complete the installation.

Video Transcript for Complete Breakdown of the Light Guide LED Trailer Tail Light

Speaker 1: Today we're taking a look at the Optronics Light Guide LED Trailer Taillight. Now, before we get into a lot of the features, I want to go ahead and show you what it looks like with power running to it. So, I'm going to turn on my power source, and I'm going to turn off my overhead lights.This is the taillight function of the unit. When we apply the brakes, you can see how the signal output increases, and it does that same thing when we activate our turn signals. Now this round trailer taillight serves three functions, such as your stop light, taillight, and turn signal light.The Light Guide Series features a smooth X shape across the face of the light. It is sonically sealed, so it has a waterproof housing and lens unit that is submersible.

It features durable surface mount technology when it comes to the construction of the LED circuit board. That better withstands shock and vibration and allows improved heat distribution and an overall thinner construction.Now LEDs make great replacements for incandescents. They last longer. They burn brighter. They're more efficient.

You don't have to worry about replacing bulbs or worry about brittle filaments. This unit features a red polycarbonate lens. It's very strong and durable. It's a recessed mount installation with a mounting grommet, and then on the back it accepts a three-wire pigtail for your wiring. Those items are sold separately.

The grommet and the pigtail wiring are sold separately and available at etrailer.com.It is SAE and Department of Transportation compliant. When it comes to the overall dimensions, starting with the diameter, we're looking at 4-5/16. Overall depth, including the housing for the plug there, is 1-11/16" deep. The power draw at 12.8 volts for the stop and turn signal light is 0.421 amps. For the taillight it's 0.114 amps.

Optronics puts a lifetime warranty on the LEDs. That's going to do it for today's look at the Optronics Light Guide LED Trailer Taillight.

Customer service five stars, product two stars. Well the product works just fine it does not fit into the 4-in hole for my RV. I actually broke the plastic around the housing trying to get it in.

This light has a diameter of 4.31 inches by 1.69 inches deep. You will need a grommet part # A45GB and a plug such as part # A45PB or part # A47PB to finish the installation. Using a bracket like part # BK45BB can make it easier to mount the light on your trailer.
