Optronics TL16RK Waterproof Combination Tail Light Kit Dimensions

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.

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.

Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

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.

It was so easy ordering my submersible trailer lights for my jet ski’s,thank you for the great price and fast service


Straight forward install. Product meet my expectations.


parts were as described and fast delive ry


I received the product in a timely manner. The problems started with installation. I was replacing an existing, non-functioning light set and the wiring appeared to be identical. I made some temporary connections and the red rear lights seemed to work with all functions. However, after hard-wiring and installing all of the lights they failed to work. The package included a bar code to access some installation videos. Unfortunately, these videos did not address the specific product I had, so they were of no use. After hours of experimenting I called for support. Support was friendly and had a technician call me back. After a couple of minutes of chatting, he informed me that this kit would not work with aluminum trailers and that I would need to install a separate, dedicated grounding connecting from all devices. Would have been nice to know that in advance, and perhaps there should be products and packages specifically for aluminum trailers.


Ordering this light kit was the first time I've used
What a pleasant experience. Ordering was a breeze and the follow-up customer service was first class.
Whenever I need trailer parts, it'll be for me. I will recommend this web site to anyone I know.
I like to shop around online to find the best deal. I went to a competitor's web site that read "low price match guaranty". So I called them on the phone. Their rep said, "We can"t price match". It was the exact same item. 25% lower price at eTrailer.
Fast shipping, excellent packaging.
And BTW, the lights worked out great.


Very easy installation! Had an issue with the running lights NOT working after installation. I emailed the team at and they helped me TROUBLESHOOT the problem. It was my vehicle. They went ABOVE and BEYOND to help me find the problem when the light kit installed perfectly the 1st time! Only took about 2.5 hours but that's because I was meticulous about all of the connections and sealing them in heat-shrink tubing for extra protection.


Everything I needed was in the kit with good instructions. Delivery was right on time, With sales follow up I don't know how you could ask for better service.

That's why E-Trailer is the only place I shop now.

Hi I am perfectly satisfied with everything I have gotten from e trailer. Will be back if and when the need arises.

I recently purchased a used boat trailer that required lights, wiring and markers to be replaced. I called customer service at with a list of questions. The representative was very patient and extremely helpful in guiding me to the product she believed met my needs. The new light package was on my doorstep in 3 days. The lights were exactly what I needed, easy to install, and work perfectly. will be my first choice for any accessory needed to repair or improve my trailer.


Note this is made in China and not great quality. Should work fine but may not last. You will need a 10mm socket or box for the tail lights.


very happy with purchase.


One stop shop for a light overhaul, had to buy 2 smaller side lights to have the full set of lights needed to re-run all the lights and wires for my boat trailer, but this kit gave me 90% of what I needed.

I did have water get into one of the boxes, but a little epoxy around the wires where they enter the box, and problem solved. Best use of a day during my vacation was re-running all of the lights. No more lighting issues every time I put the boat in.


This is a cheap kit (made in Tiawan) I wish they sold the same kit with better quality that wasn't LED .The parts that I removed from the trailer were of much higher original quality. I would not recommend this product to anyone. The only parts I used from the kit were the tail lights. and license plate bracket. I threw away the side parker lights and went out and bought good ones.


Was exactly as described, works perfectly with my trailer. Would give it a "Excellent" rating if it had included more thorough instructions for attaching the side marker lights and how to waterproof those. Otherwise great!


Great customer service. Quality part. Easy to install and works perfectly.


Bolted right up very bright. Would by again. Highly recommend

Great! This package set up is exactly what you need for replacement or new set up. Great deal for price range.
Robert E - 04/28/2021


There was no information as to the gauge of the wire or if a center brake light was supported. Good hardware, but more documentation would make it better.


Easy installation. Harness, at 25', was just too short for my trailer, which is 22'.


Great price


Purchased this product to rewire a 1980"s double-wide snowmobile trailer. These lights replaced the old ones perfectly, at a great price.


excellent product a nice addition to my tiny house
every thing was color coded was a easy hookup

Good morning I have been well satisfied with the lights I purchased. I was building a tiny house for a friend and I needed them to move it about 350 miles to the Virginia coast they worked perfect. I was satisfied and most importantly she was also. when I need lights again I know who to contact

I The product and service was great - online. I ordered this product last week and with in a week. I didn't have to leave home. I will do future business w/etrailer.

Thanks for the timely service


Wish there were more than six wire clips. Washers to backup lock washers would of been nice. All in all very happy with product.


Nice product. All high quality parts with all the hardware included. The customer service and communication made this transaction a step above what I've been accustomed to.


Kit came with everything needed. Great communication from their staff. Product was great quality and priced right.


Great product
