Video Transcript for Optronics ONE LED Trailer Tail Light Review

Today we're going to be taking a look at and installing the Optronics 1 LED Trailer Light for the driver's side, part number STL009RB. If you're looking for the passenger side light to go with this, it's going to be part number STL008RB. The Optronics light features seven functions. It's a stop light, a tail light, turn signal light, side marker, side reflector, rear reflector, and a license plate light. It's a sealed waterproof construction that is designed to be submersible. The 1 series provides a bright light using fewer diodes than other LED lights. It's a durable surface mount.

It better withstands shock and vibration and allows for improved heat distribution. The LED is a great replacement for your incandescent light. It's going to last fifty times longer, be more efficient with brighter light and less power output. There are no bulbs to replace and you don't have to worry about those brittle filaments that break. It has a molded plastic housing with a red and a clear acrylic lens.

It has a three wire pigtail and is DOT compliant. We've already removed our old light and we have our holes lined up so we can take our new light. It comes with a flat washer and a comical tooth nut. We're just going to place the light under the trailer and feed our wires through the hole that we have on the side. Put our flat washer, your comical tooth nut, and we'll slide them down. We want to make it snug but don't go too crazy because it's plastic and you can break it.

Our light does come with a built in ring connector but we're going to go ahead and cut ours off because we have a ground wire that's already in place. We'll go ahead and strip it back about a quarter of an inch and we'll do the same thing with our ground wire. We're going to be using the Deka Heat Shrink Butt Connectors available on our website, part number DW05744-10. We'll crimp that on, take our white wire from our light, twist it up, and we'll slide that into the hole. Crimp that, give it a tug, and we're just going to match our wires color for color. You have the brown for your running light and the yellow is going to be your turn signal and your brake for the left side.

We'll strip back our wiring. They do come pre-stripped but it's not really enough to do anything with so you have to strip them back a little more. We'll take our butt connector and we're going to connect our brown wire to our brown wire. Give it a tug. We'll do the same thing for our yellow wire. Give that one a tug. Now we can heat up our butt connectors and it'll shrink the tubing around the outside of our wiring to help keep out moisture and corrosion. As you can see, it's starting to heat up and it's melting around the outside of the wire. To clean up our wiring look and to help protect our wires, we're going to go ahead and put some wire loom on it in the half inch diameter available on our website, part number 459075-1. We'll take our loom and put it around the outside. A little bit of electrical tape around it to keep it on there. Now we can slide it up our wire. A couple of pieces of electrical tape around the center here where the butt connectors are. It will help keep them intact. We can trim off the excess. Take a little bit of electrical tape and start it around the wire and we can slide our loom over the edge. That will help keep it from sliding down. Now we're going to take a half inch metal loom clamp, available on our website also. Part number A0500. We're going to place it around the bottom. We'll take a self tapping screw and we'll secure it to the trailer. That'll keep our wiring intact. Let's go ahead and test them. We'll try our our marker light, our brake light, and our turn signal. That's going to do it for our look at and install of the Optronics 1 LED Trailer Light for the driver's side, part number STL009RB.

These lightweight LED trailer lights were a replacement for the original lights on my trailer. They mounted easily and work great. They are bright and easy to see from the rear, I should have replaced the old lights sooner. Also, the price was very reasonable, what's not to like about that? 172865

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

I backed into tree with trailer and broke driver side light, but I knew just who to contact because a year or so ago my friend backed into his house and broke passager side light. I kept etrailer in my favorites because I had a very good experience the time before. The product is of high quality and at a good price but the thing I liked best was I received 2 different emails thanking me and gave me a number to call if help was needed. Never had that before. Plus this was not a big order but got the same treatment as if it were. 373075

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

Although the trailer tail light has yet to be installed , I give it 5 stars because of how it is portrayed on the website which encourages the user to install it himself. The vehicle specific videos made the decision to purchase and install the products a slam dunk 498107

Review from a similar Optronics 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

Review from a similar Optronics ONE in Trailer Lights


Good quality, and functions as advertised. Brighter than the original incandescent units they replaced, but not quite as bright as I had hoped for. It took more time than expected to install these lights, but I was pretty cautious about leaks and used butyl tape under the units, and silicone around the outside. I previously updated all of the clearance lights to LED with Bargman conversion units from etrailer. Our trailer is now 100% LED. 389343

Review from a similar Optronics ONE in Trailer Lights


I bought these to add on to my existing trailer lights so they would be easily visable above the extras loaded on the rear platform, and so my license plate would not be partially obscured (a violation in many states). They are just as bright as the original equipment, if not brighter. The only criticism I have is the wiring does not follow the standard color code, so brown to brown etc. did not work. It was easy enough to fix, so wire it then test before you make final connections and seal it up. 307851
