Optronics STL002 Series One LED 6 Inch Oval 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.

Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet (A70GB - 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 - STL002AB Review

Today, we're going to review part number STL002AB. This is the Optronics ONE 6" oval LED trailer turn signal parking light with the amber lens. This amber oval light will serve as your parking light and your turn signal. It is a sealed waterproof housing in lens unit. It does use the surface mount technology, and it protects the LED from shock and vibration. Basically, the LED is mounted directly onto the circuit board instead of through holes. This will offer better heat distribution and also thinner construction, and it helps withstand bumps and shaking.

It is a long-lasting LED. It's great replacement for incandescent lights. It lasts about 50 times longer. The other nice thing with the LEDs is there are no bulbs to replace or no brittle filaments that can break, and they are more efficient and provide brighter with less power output. It is a polycarbonate lens and housing. They are sonically sealed and waterproof.

It does use the industry standard 3-prong plug for connecting to your trailer, and it does install with a grommet. Those parts I am going to show you here in a minute. They are listed on this product page for the light as related products. We do sell them separately on our website. Basically, I am going to show you the straight . This first one is the straight 3-wire pigtail plug. It's part number A45PB.

Basically on the very back, you'll see the 3 openings. Just take your straight plug and push it in. There you go. You'll see they call it a straight pigtail because the wire comes straight out from the back of the light. The other option is they do also offer a right angle 3-wire pigtail. It's part number A47PB, and this one when you plug it in, you can see that the wires will come out at a right angle from the light in case you need to have any clearance problems behind your lights. The grommet they use is the rubber grommet, part number A70GB.

Basically, you would just pop your light right into the grommet just like that. Then, this would all install into the separate mounting bracket. Again, this is BK70BB. You can see it's a metal bracket and has the mounting bracket here at the top. Basically, you just pop your grommet with your light in right into the opening of the bracket. Again, those parts are all sold separately on our website. This light is Department of Transportation compliant. It does meet the Federal Motor Vehicle safety standards and the Canada Motor Vehicle safety standards for automotive lighting. I do want to give you some dimensions on this. The overall length, edge to edge, is going to be right at 6-1/2". The height, top to bottom, is 2-5/16", and the depth at the very widest center portion is going to be right at about 1" deep. That does have a lifetime warranty on the LED. Now what I'm going to do is we're going to plug this into a 12-volt power supply just to show you. We're going to take the straight plug and go ahead and plug that in. There we go. With it plugged in, I'm going to plug this into a 12-volt power supply. Again, you will see it's 3 wires. The white wire with the eyelet is for the ground. The red and the black are the power wires. Red would be for your turn signal. Black would be for your parking light. We'll go ahead and hook this up. With it hooked up, I'm going to go ahead and turn off our overhead lights and go ahead and turn on our 12-volt power supply. There you can see the parking light and then your turn signal. The turn signal is very bright. Again, this is the Optronics ONE, which means it's 1 LED in there, a very bright LED. I'll going to go ahead and turn off our power and turn back on our overhead lights. That should do it for the review on part number STL002AB. This is the Optronics ONE 6" oval LED trailer turn signal and parking light with the amber lens. .

Great product to replace incandescent lamps . Bright and easy to install . Great and easy shopping on website. Quick shipping and low cost shipping too! Will buy again when needed.


Order arrived quickly with no damage. They're installed and are much brighter than the original incandescent bulbs. Nice.


Everything is just as I wanted. Will purchase from these guys again.


Had every item in stock and shipping was very prompt. Also had the order exactly as I ordered. Would order again.




Absolutely outstanding service in every way !!!!
These folks would have received 10 stars if that many were available. They are absolutely a pleasure to do business with. They are very friendly and professional, helped me identify the part I needed and shipped it super fast to help me with a critical timing issue for my boat trailer tail light need for an upcoming fishing trip. I am very grateful for all their help and highly recommend I’m a repeat customer and this is the only place I’ll shop for my trailer needs !!!!!!


Loved the easy installation and plug that eliminates splices, but my light has already stopped working. maybe they just aren't suitable for a boat trailer.


Had a scratch on one of the lenses upon receipt. I notified e-trailer, they handled it right away sending q replacement. It’s nice to see that customer service does still exist. Thank you


I couldn’t find anyone that had the tail light I needed for my trailer.after looking at every place I could find I finally looked on etrailer web site and found what I needed. I called and spoke with the representative to make sure it was the right one. The representative was very helpful and determined it was the right part. The part actually got delivered quite a bit faster than expected. Thank you


Light got water intrusion and stopped working after a months use. Warranty isn't honored unless shipped back in for examination. Leaving you to have to purchase another light in the mean time to stay legal


Great place to order parts.I ordered replacement tail lights for my boat trailer and they were a perfect fit.I called and talked to a sales representative, they were very friendly and knowledgeable and easy tracking of my shipment.


5 min job, worked great


Great company to work with. Excellent inventory, customer service was amazing. I called and spoke to Alex and she was very pleasant to talk to. Plenty of installation videos available. As a RV park owner I am sure I will be using them again in the future.


I have a 2021 bass tracker boat and trailer. I backed into a pole and broke the tail light. I ordered this one and received it two days later. Fit perfect. No issues what so ever. Great product great service. I would recommend it.


These were a perfect match for my existing tailights. A quick replacement of the old bulb style to the new LEDs. Fast change out and worked just as expected.


Easy replacement and install of new light - all lights worked after connection- just hope it’s water proof after submerged-


Plug and play for my 2018 tracker trailstar trailer.


They are a great fit for my 2023 Bass tracker trailer. These are the exact replica of the factory lights to come with the trailer.

I’ll shop here for more parts in the future


Product and service brilliant.
the big things in service have been sorted, eg. good product, value for money (not cheapest) delivered in good condition in a predicted timeframe, it's the little things like an email with tracking url that has ALL the information you need... WITHOUT HAVE TO TYPE IN A TRACKING NUMBER , NAME, ZIP ETC. And same with review, click on a url in an email and enter your comments with pictures .....SIMPLE. so many other companies just make these types of things too complicated and onerous for the customer to provide feedback. Also each person in the process is named! Brilliant, personal and just nice. I wish you guys were responsible for all of my transactions for all the things I buy online. Thank you to all of you at etrailer fantastic job.


Part fit perfectly no problems after a year.


Perfect fit. I went through Bass Pro first. Figured since that was where I purchased the trailer it was a no brained. Needless to say they were no help. I will be using e trailer from now on! Two thumbs up!


The trailer lights were the correct ones and installed easily less than 10 min. and worked perfectly.


I wished they have put the light in some kind of cushioning, the light was put in a box with nothing to protect it from damage.


The right product perfect match . Plug in and mount to bracket 5 minute job
