Optronics STL002RFB One Sealed Combination Tail 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.

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.

Video Transcript for Optronics Trailer Lights - Tail Lights - STL002RFB Review

Today we're going to be taking a look at part number STL002RFB. This is the itronics 1 LED trailer light. The oval trailer light is going to serve 3 functions. It's going to work as your stoplight, sail light, and turn signal light. It's going to feature a sonically sealed waterproof design when it comes to the housing and the lens unit, so it is a submersible trailer light. The 1 series is going to provide a bright light using a single diode, unlike other LED lights that feature a multi-diode design.

It's going to use durable surface mount technology when it comes to the construction of the LED circuit board. That system is going to better withstand shock and vibration. It's also going to allow for improved heat distribution. That LEDs are going to make great replacements for incandescent lights. They're going to last a lot longer.

They're going to burn brighter. They're going to be much more efficient, and you don't have to worry about replacing the bulbs, and you don't have to worry about inaudible 00:48 filaments. The lens and the housing on this unit's going to be made from a poly-carbonate material, we're going to have the red lens with the black housing. This is a surface mount installation with the built-in flange here on the backside. Your hardware is not included. It's going to feature a 3-wire pigtail, so the white's going to be for your ground, black is going to be for tail lights, and red wire is going to be for your stop and turn signals.

It is department of transportation compliant. If we take the measurement of the light face, just measuring the lens portion. Going in this direction, we're looking at about 6 1/2", and going this direction we're looking at about 2 1/4". Take a measurement overall, including the flange, we're looking at about 7 1/2", and about 3 1/4". The mounting holes on this unit are going to separated on center, going this direction by 2 3/4", and then going this direction our mounting holes are going to be separated on center by about 7". It's going to contain 1 LED, or 1 diode.

The power draw at 12.8 volts for the stop and turn signals, 0.25 amps. For the tail lights, 0.007 amps. Itronics is going to put a lifetime warranty on the LEDs. We're going to go and hook it up to our external power source. That way, you can see what it looks like with power running to it. We'll simply make our connections here. You can see here, it contains 1 LED. Sends out a nice, consistent signal. This is the tail light function. Then when we apply our brakes, you can see how that illuminates for a stronger signal output. It's going to do that same thing when we activate our turn signal. That's going to do it for today's review of part number STL002RFB.

Average Customer Rating:  4.8 out of 5 stars   (668 Customer Reviews)

6-1/2" x 2-1/4" Oval. Waterproof trailer light serves 3 functions: brake, tail, and turn. Unlike other LED lights, this ONE Series light provides bright illumination using a single diode. Surface mount with flange. 3-Wire pigtail.


I have used many of the Optronics LED lights. Good brightness, good prices, seem fairly durable. These were going on the back corners of a hitch cargo carrier.

Just be aware that this is called a surface mount, but has the wires out the back. You will need a hole in the panel to route wires, or a spacer to lift off the surface. I wanted a true surface mount with wires out the side of the light. I made it work. No issues with the light, just need the catalog listing edited to be clear.


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.

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!

product was as described, and arrived in a timely fashion. looking forward . to installing lights. installation should be simple, and as shown


This was an excellent replacement for the light that broke on my trailer. Very easy to install. Connection labels on back.


Excellent product, and service from etrailer has always been good.


One year later, and 10,000 miles and counting! Lights have not leaked and worked fine,,,yea watch after I send in this review they will crap out,,,hope not!

Well the trailer lights are still working. And I have plans to rebuild the trailer and will use these lights some more. Hope that I will never have to buy another set of light EVER.

Review from a similar ONE in Trailer Lights

These lights came OEM on my 2020 LoadRite 5 Starr trailer. The passenger side stop/turn went bad after 1 submersion. I replaced it. The drivers side stop/turn went bad after 3 submersions. I replaced it. The replacement passenger side stop/turn went bad after 2 submersions. In total, the trailer has been submerged 6 times and I've been through 4 of these lights including the originals. Stay far away from these lights.

And for those who might think I'm misdiagnosing the issue, the lights were tested by direct connection to a 12 volt power supply after working my way down the whole wiring harness.


Review from a similar ONE in Trailer Lights

The tail light I ordered was a drop in replacement for my 16’ tracker boat trailer. Installing the new tail light assembly required cutting the pigtail connector from the old tail light assembly and soldering 2 wires.

Item was packaged well and my shipment arrived quickly. Tail light assembly appears to be of high quality construction.

Delighted customer, will do business with ETRAILER.COM again.


Review from a similar ONE in Trailer Lights

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.

I bought lights and Tyres about a year ago, and this is the follow up. All great, I am just as pleased with the products and service as I was when I bought them. And again I have been sent a reminder email to ask my opinion a year later.....brilliant. thank you.

Review from a similar ONE in Trailer Lights

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


Review from a similar ONE in Trailer Lights

These are a bolt-on replacement for the stock lights on my Lowes 5x8 trailer. I got two of the "passenger" lights, because I moved the license plate to the back ramp/gate, and I got a separate license plate light for that. These lights work very well - I used heat shrink tubes with a low temp solder ring in them, to splice the connections to the stock wiring.


Review from a similar ONE in Trailer Lights

So, I rewired my trailer to not have any wiring connections underwater during a launch operation. To accomplish this, I placed the "etrailer" tail lights and brackets on existing guideposts, then using two "shielded electrical extension cords" I routed them from the tail lights to the trailer hitch plug-in connector.


Review from a similar ONE in Trailer Lights

Tail lights were the same size as OEM. Mounted easily and work great. Excellent price and the lights were delivered promptly. I have always been very satisfied with the trailer purchases.
