Optronics STL003 Series ONE LED Round Sealed Light Diagram

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.


Weathertight Connection

Optronics Weathertight Connection

This light has a weathertight connection as pictured above (weathertight plug sold separately). This type of connection is designed to help block out moisture.


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 - STL003RMB Review

Today we're going to be reviewing part number STL003RMB. This is the ONE Series, Submersible LED Trailer Light from Optronics. The round trailer taillight is going to serve three functions. It's going to function as your stop light, your tail light, and your turn signal light. It's going to feature a sonically-sealed waterproof housing, as well as a lens unit, so it is submersible. The ONE Series provides bright light using fewer diodes when compared to other LED lights. It features durable surface mount technology when it comes to the construction of the LED circuit board.

What that means is it's going to better withstand shock and vibration, and it's going to allow for improved heat distribution. LED systems are going to make great replacements for incandescent lights. They're going to last about 50 times longer, they're going to be much more efficient, and you don't have to worry about replacing bulbs, or burned out filaments. When it comes to the lens and the housing, it's made from a polycarbonate construction. It's going to have the nice red lens with the white housing. This is designed to be a recessed mount installation, with a mounting grommet, and hardware.

Those items are sold separately, you can find those here on our website. The plug here on the back is designed as a weather tight connection point. It's going to require adapter part number AL45PWTB. That part is sold separately, and it is required to work with an industry standard 3-prong plug. This light is Department of Transportation compliant. It meets FMVSS108 requirements and CMVSS108 requirements for automotive lighting. We're going to take a measurement of the diameter, that's going to give us a measurement of about 4 inches.

Optronics is going to put a lifetime warranty on the LEDs. That adapter that I mentioned is going to look like this. It plugs into the plug here on the back, again, this is going to be sold separately, and it snaps into place for a nice tight, secure connection. Now we can go ahead and hook up our 3-prong plug. Then we'll be able to turn off our overhead lights. You can see here it sends out a really nice consistent signal.

This is going to be the taillight function, and then when we apply our brakes, you can see how the light brightens up. It's going to do that same function when we apply our turn signal. That's going to do it for today's review of part number STL003RMB. This is ONE Series Submersible LED Trailer Light from Optronics. .

The tail lights that came on our boat trailer were the $1.95 incandescent variety. They quit working after the first season. I replaced them with these sealed LED units which have worked fine ever since. 433514

These lights mounted up and wired easy with out any changes to the trailer and are brighter than the original ones. First time I use LED trailer lights and hope they will be trouble free for many years. Purchased two sets of lights I will change out on my second boat trailer. In the pass I have to change bulbs two or three times a year, I hope this will change. 425636

Took a while to have a work basket with headache rack built for my Honda Pioneer 500 which is the reason I purchased these GREAT stop/turn lights. These lights are perfect. Take abuse and vibration with no problems! Super easy to mount and bright as I've seen. Perfect! 503927


Comments
To date, 5/3/19 the trailer lights have endured the riggers of neglect and abuse. No chips, cracks or failures...ZERO maintenance to boot. My kinda product. You can not go wrong on purchasing these bullet proof literally and figurative stopturn lights!

Review from a similar ONE in Trailer Lights


So i have a 94 Jayco pop up that one of the tail lights got smashed. The company that made those lights is no longer around. After some searching on etrailer.com I decided on these LED lights. Price was right. My only real complaint is that these lights come with nothing. No screws, no instructions, no seals. So when I pulled my old lights and found that they had 4 wires and these lights had 3, time to do some research. None of the wire colors matched up. Not the trailer wires, not the old lights etc. On etrailer there is a video describing the lights in detail. Watch it. He goes over what color wire does what on the new light. I hooked the trailer up to the car to figure out the old lights wiring scheme. I was able to figure it out from there, though you cannot wire both sides up the same, if you do when you put the turn singles on they both flash. I had to leave the brake light wire disconnected on one side. Brake lights still work without it. I used plumbers putty to create a seal. That is also what they used on the originals and I used the original screws to make new holes and mount the lights. All in all it worked out but instructions would have been greatly appreciated!. I am sure etrailer would have jumped in to assist if I asked but it was not needed. Pictures posted. Old lights on bumper for reference. 704269

Review from a similar ONE in Trailer Lights


I purchased these to replace my tail lights on my Rockwood trailer. The units I removed used the regular incandescent bulbs and even though they are only 2 years old they were already acting up. They get corroded in the socket areas even with trying to keep them clean. These fit perfect (exact same fixture) are twice as bright the flash is faster (with the LED fitment) and the obvious choice for replacement/upgrade with very little fuss. These have a separate tag light that is plenty bright to illuminate your license plate area. The pricing was excellent and the shipping was extremely fast. Communications with this company is spot on. If you have a question they get right back to you in short order. They also give great recommendations as well. The tail lights were delivered Friday and I installed them in 20 minutes on Saturday. I have purchased from you guys in the past and will in the future. Thank you... 416636

Lighting for LED is a little dim in my opinion but the 3 way bullet connectors is great easy way to change a tail light. If the light was brighter and was completely sealed I’d give it 5 stars. 828718

Haven't tried them on the road yet, but these seem well made. The edges of the lenses are flush and there isn't even any molding flash. I tested them and holy heck are they bright! Someone would have to be blind to miss the brake lights on these. The studs are the same spacing as the round incandescent tail light units that used to be pretty popular on utility trailers. The back of the light has a color code guide (a very nice touch) and notes that the mounting studs are the ground return. Not mentioned is that there's also a white wire (the one with the ring lug) in case you don't want to rely on the chassis ground. Personally I recommend having a continuous ground wire for your trailer lights; chassis grounds can be unreliable, especially in a corrosive environment. 827925
