Optronics STL17 LED Combination Tail Light Diagram

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 circuit board is sealed, which means that water will not damage the diodes or circuit board.

Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.

To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Average Customer Rating:  4.9 out of 5 stars   (141 Customer Reviews)

The light was an exact match to the broken one. I soldered the wires and covered them with heat shrink tubes to complete the installation.


I got these led lights to replace my original trailer lights. Easy to install and a lot brighter, definitely recommend them for anyone wanting to replace there old trailer lights.

Still going strong. Definitely worth the buy.
Al T - 06/16/2021


Delivered quickly, easy installation, MUCH brighter than the incandescent lights that were on the trailer. Mounted the same, so installed in less than 30 minutes. Looking forward to not replacing bulbs every time we launch the boat.


I have been dunking these lights in salt water every weekend for more than a year on my boat trailer. Gone are the days of chasing corroded bulbs and sockets. Remember to use heat shrink on the electrical connections to keep them waterproof. On top of that, these lights are nice and bright.

These lights continue to take dunking in salt water. It feels great to know that each trip doesnt start with an effortto find that burned out bulb or corroded connection. Be sure to use shrink tubing on the wire connections, though.
Dick B - 06/22/2020


Bought this to replace a tail light on my boat trailer that had lost its seal and was not working. The new light arrived in good condition, fit properly, was easy to install, and has worked well for the past year.


I appreciate your help in selecting the correct tail light for my trailer. I was surprised I received it as soon as I did. It arrived a week sooner than I expected. Now I know where to go for all my trailer parts. Thanks


Easy to install in place of older bulb unit. Nice to not have to disconnect trailer when loading/unloading boat.


I called up and was assisted by a very friendly and knowledgable young lady that helped me get exactly what I needed. The transaction was as painless as possible and took all of about 5 minutes. I had already found the left LED light part number and she told me the part number for the right side light, both matched up exactly to the shape/size and mounting configuration of my existing light that had bulbs. My package arrived in great shape in only 2 days and installation was a breeze - around 5 minutes a light. The LEDs look great and gave my 4 year old boat trailer a new look. I highly recommend etrailer for any lighting needs you may have and also the LED lights. No more bulbs to blow out and no more worries of corrosion of the fixtures.

Anytime I need anything that you folks carry...Ill be ordering from you. You are Top quality folks...have great products at fair prices and I couldnt have been happier with the whole experience. The fact that youre checking back just proves my point.
JP M - 08/18/2016


I installed these on my boat trailer, replacing a cheaper LED light set purchased elsewhere, which failed after about 1 year of use, and failed with an internal short. I installed these a year ago, along with a new trailer harness. Work great.


Bought this as part of a complete trailer refurb. Nice product, although priced a little higher than I thought it should be. Looking forward to installing. Sales rep was very polite and helpful.

This project turned out great! I really like buying from etrailer. They always have what I need, along with great customer service and fast shipping.
Kenneth - 01/20/2020


I needed to replace some of the lights on my boat trailer. The old light were incandescent and some of the bulbs had burned out, securing screws were rusted. Product was exactly what I was looking for. Links on each product web page provided very good description and product information. Thank you for great selection and process.

I am very happy, the lights are working great, with no issues. Thank you
Phil Z - 11/21/2017


Excellent product. Easy to install and LED optics are much more visible. etrailer made it easy to order and product arrived on time.


There were a perfect fit replacement for my 1992 Tracker Trailstar boat trailer. It had Wesbar 3348 tailights on it. These look exactly the same but they have sealed LED capsules inside. It was gonna be the same price to replace the old style bulb capsules in the Wesbar's as it was to but these whole brand new sealed LED tails. The are very clear and bright. Huge improvement!


The review and ordering process went quite smoothly, especially since it was my first time to the website. I was amazed at the vast amount of inventory at etrailer and decided I will be back. Tracking of my order was easier since the tracking info was preset into the url as opposed to being directed to a general site. Delivery was in the allotted timeframe. My thanks go out to Herb for securing the 3-5 day express shipping. Thanks etrailer.


LED the only way to go nowadays. This is a good quality product. etrailer service and shipping was perfect.


Perfect just what I needed


Replaced broken tail light on a 2003 520 very Ranger boat trailer. I changed over both lights as I am not interested in spending $170 on not exact replacements. These lights work great. Wiring diagram would help. Not a big deal. If you get wires crossed up, it is obvious that reversing connection is needed. I ordered stl 16 and 17.


The is the EXACT same light for half the price for my MagicTilt Trailer! VERY HAPPY. Thank you.. now if i could just quit backing into the planters on the side of the house would fix the problem!

The lights are still going strong after a year! No problems with water or night driving. Light up every time!
Andrea B - 07/17/2014


i ordered the LED tail lights STL16RB and the STL17RB [ license plate light ] to replace the original boat trailer tail lights.They both fit perfectly in the original mounting holes,and very easy to install.It took less than an hour to do both lights.They fit so well it looks like they came with the trailer!


These are excellent lights, very bright. an exact replacement for my existing lights that had begun to leak a little around the seals. These were easy to put on. I used crimp wire splices to attached the wires then put heat shrink tubing on them to seal. I don't submerge often so we'll see if i have any problems with this attachment. etrailer shipped promptly as always.


Purchased a set of these lights as replacement/upgrades on my existing standard boat trailer lights. These LEDs lights perform exactly as described. They are completely water tight. After one full year of use, they perform as well as the day I installed them.

by: has turned out to be a great resource for all my trailer parts. I found them by accident after I got my first trailer. I recently bought a pair of LED Tail lights and they were shipped within hours of getting my order. They were a direct bolt-on. Couldn't have been easier to replace. is my new favorite for all my trailer parts going forward.


This was a replacement for a damaged tail light on my boat trailer. Great tail light, clarity of the tail light is amazing and it's waterproof! Ordering was a breeze, shipping took a little longer than I expected, i.e. 7 days. But, I was provided with a tracking status once the order was processed. Thank you!


Flawless throughout the year bouncing along the highway and loading and unloading my boat in frigid water. Twice as bright as my previous "sealed capsule" tail lights, which I would have had to replace 2-3 times in that period. Wish I had found them years ago!


One of the encased waterproof housed bulbs was shot on my trailer, and it was the style where I had to buy the entire unit.. So at that point, I figured I might as well replace both with new LED models. These are bright and amazing, I love them. The etrailer person in the forum posted exactly what I needed, shipping was quick, and installation was a breeze.

  • Replacement Tail Light Lens on a Snowmobile Trailer with Optronics Tail Lights
    If your tail lights look like # STL16RB or # STL17RB, then you can use the Replacement Tail Light Lens, # A16RB. This is the correct replacement if the tail light has incandescent bulbs. If it is an LED tail light, use # AL16RB. If the lens portion is deeper on your lights than those pictured, you may have a 26 series light like # STL26RB as an example. The 1/16 of an inch would be the very first tick mark after the 8 inch line on a ruler (provided the ruler measures in 1/16 increments)....

These lights use pigtail # A47PB and will fit the mounts currently on the trailer.

An under 80 inch taillight does not have the clearance light built in and an additional red, rear side marker light would be required if you used an under 80 inch rated light on a trailer that is over 80 inches wide.

When backing your boat trailer into water we still strongly recommend you unplug your trailer wiring before the trailer get submerged.

    If you have the Wesbar model 3504, the closest LED Equivalent we offer would be the Optronics # STL16RB for the right hand side and # STL17RB for the left hand side. These lamps measure 8-1/16 x 2-7/8 x 2-13/16 inches, very similar to what you have now. LEDs draw only a fraction of the power of incandescent bulbs, but put out more light. They also last a very long time.
