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.

replacement LED for one that the turn signal guit working that was installed about 2 months ago.



Had to replace the right light assembly because the center elements that do the turn signal melted.


The tail light arrived in great shape and worked flawlessly after installation. Thanks.


Excellent Quality and product works well and was exactly as described.


My item was very easy to order and arrived sooner than anticipated. I was very pleased.


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.


After 1 year still waterproof. Works like a charm


Factory wire leads need to be a little longer and ground wire needs to have a ring terminal with an integral heat shrink wrap. The open crimped ring terminal with exposed wire provided on this light will quickly corrode and fall apart on a boat trailer when exposed to salt water immersion. Otherwise, a good quality LED light.


Exact replacement at no charge for our drivers side trailer tail light! Have yet to put it on so we shall see.


work great


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.


Part was exactly what I needed. Great price and quick delivery.


Product fits perfectly


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.


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.

Dick B.


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.


This light was a much needed upgrade on my boat trailer to make it look more modern and not so old. It is very bright, fit right into the existing holes I used for the old lights and wiring it up could be easier! Have yet to dunk it in the water but I'm sure it will be just fine! Great Product!

Marshall H.


Its been a year and these lights are still working as advertised. Been able to launch the boat with my trailer lights still hooked up no problems!


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.

Phil Z.


I am very happy, the lights are working great, with no issues. Thank you


Odelia is awesome, she deserves a promo tion


The part seems to be fairly common and available from a number of sources. What sets etrailer apart is the uncommon service they provide. Absolutely first class. This is the way it should be done. Kudos to Paula S !!


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.

Al T.


Still going strong. Definitely worth the buy.


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!

Andrea B.


The lights are still going strong after a year! No problems with water or night driving. Light up every time!


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.


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.


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.


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!


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.
