Sealed, Waterproof Trailer Light

The waterproof construction of these lights make them ideal for use on trailers that may be submerged, like a boat trailer. Each 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.

P2-Rated or P3-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated or P3-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Average Customer Rating:  4.8 out of 5 stars   (562 Customer Reviews)

So far so good. I've had miserable experiences with trailer lighting in general so if these make it more than two years without failing I'll call that a win. The Optronics products overall seem to be good quality and at a good price. I've replaced all the side markers with the Optronics and those have been working well too. That said, I keep spares on hand. I also apply dielectric grease to all wire connections and try to reapply that grease once or twice a year.


I was an Idiot last week and broke my drivers side light , so I bought a new pair ,very simple to install and they look good right next to my roller guides


The Optronics LED Combination Trailer Taillights are still working like new after 1 year. They are very bright for extra safety when stopping and pulling a Trailer on the expressway. I highly recommend them.


Good lights. All ready installed on my utility trailer


Decided to change all the lights on my boat trailer to LED. These were easy to install, and work well.


Simple to install and 100% better than what came with the trailer. If I knew then what I know now...I would have replaced the lights years ago before I had to deal with a replacement at an inopportune time.



Continues to work like new. Dependable lights that I can count on.


Excellent product. Well constructed and bright lights. Wiring and attaching to trailer myself saved a lot of money over dealer estimate with same results. I have had zero problems with performance during the first year.

Pete T.


No problems encountered during 1st year of use. Excellent product


Trailer light are fantastic. Installation was easy and lights have been trouble free. Very glad I bought!


I replaced my BRAND NEW trailer lights that leaked with these bad boys, Best purchase EVER! Still working and as bright as when I bought them a little over a year ago. Much brighter then OEM. Customer service is top notch!


Haven't installed yet,they should be fine. I don't think I have ever got a bad product from trailer!


Good tail lights. Everything they were supposed to be.


Easy install, superior product!


The lights work on the boat trailer just fine
I ordered the Wrong size lights but got to work anyway
I kept blowing the light bulbs on the old lights and
The new led lights have not had any problems .


Been working great on my boat trailer in and out of the water


These were replacements lights for my Ranger RB190 Trailer. They are the same lights that were on the trailer already, so they installed easily. Glad I remembered to search etrailer for replacements.


Excellent help was provided and the parts came quickly. 2nd time using etrailer, one of the best buying experiences I’ve had. Thank you for providing great customer service!!


The others lasted two seasons...hopefully these last as long or longer


Package delivered promptly. Appeared packaged well. Lights installed easily and operate without issue whatsoever. I decided to purchase this particular brand from this particular retailer because of the lifetime warranty on the LEDs and etrailer's positive reputation.

I am, however, a little disappointed that the lens of one of the lights looked a little scuffed up... as if it had been rubbing against the inside of the plastic packaging. I know things like this don't remain pristine forever, but when you purchase something new you want it to look that way!


We have 30 trailers and the Optronics have the least problems


A good replacement for my others that met a rock when I was backing up. Bright and work well.


Product as stated and fit on my trailer with out a problem


Easy install, matched right up with the factory halogen setups. These are nice and bright to include the license plate light. Very happy with them and they seem quality enough to last a good while. Would recommend to a friend.


Very fast delivery. Lights have been mounted, which was simple and straight forward. Every thing hooked up easily and the lights work as they should.


Easy to install. Looks great. Only problem is the right light is a lot dimmer than the left. Still got me to the lake safely but still should be equal in brightness. Checked ground with voltmeter and other connections and all look good. Pretty sure i got a bad light. Will contact customer service and see what they can do. Would be five stars if the light is replaced with a good one.

I know you have checked the ground however this does sound like a ground issue. The ground should not show any volts on a tester. You can try cleaning how it attaches to the trailer or you can run a ground wire back from the main ground wire of the trailer to the trailer connector and that should help.


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

  • Trailer Tail Lights Stop Working When Headlights on Jeep are Turned On
    It could be that the lights # TLL160RK are malfunctioning but since the problem only occurs when the headlights are switched on for your 2003 Jeep TJ I think there is either a faulty connection or ground. Have you tried testing the 4-Way flat on your Jeep with your headlights on? If you haven't done that yet see if that makes a difference. You can also try testing your trailer with a different vehicle to see if it gets the same results. Start off by checking the connector on your Jeep...

  • LED Trailer Taillight that Has Mounting Studs that are 4 inches Apart
    Hey Bruce, so the mounting studs of the Optronics LED Combination Trailer Tail Lights # TLL160RK that you referenced can be set exactly 4 inches apart so this light kit would work great as a replacement and would install easily. These are also LED like you said you were wanting too so they fit what you are looking for in that regard as well.

  • Troubleshooting Optronics LED Combination Trailer Tail Lights TLL160RK without Turn Signal
    Since wiring color can vary by trailer manufacturer it is a good idea to test the wires for function on the trailer or make sure they trace back to the correct circuit before matching up wiring on the light part # TLL160RK. It is not always reliable to go by wire color. You may also want to check the main ground on the trailer is properly grounded to a clean bare metal surface of the frame. Also check the wiring for any frayed or damaged wire that may need to be replaced. Since the light...

  • Recommended Replacement 8" x 3" LED Tail Light for Boat Trailer
    I recommend using the Optronics LED Combination Trailer Tail Lights part # TLL160RK to replace both tail lights on your trailer. These are standard rectangular 8" long x 3" wide tail lights common for boat trailers. They are also LED. The wire colors might not match up but so long as you attach them by function there won't be any issues. I have attached our selection for you below as well but the above should work. If you want the tail lights to match, odds are you will need two news ones.

  • Replacing the Taillights On a 2003 Monaco Knight Motorhome
    The wires on your new taillights should be labeled. If they are not labeled then all you need to do is apply 12 volt power to each wire to see which function it activates. Then for the motorhome you will need to use a circuit tester and test each of the wires for the taillights while they are active. That will then let you know which wire goes where (red to red or white to black). The reason you must test is because one light/motorhome manufacturer can use a red wire for the stop/turn...

  • Replacement Taillight for Zieman Trailer
    I don't have any way to look up parts for a specific trailer, if you can send photos I'd be glad to see if we have any options for replacement. That said, it looks like some use them use a fairly standard rectangular taillight for trailers over 80" wide. It's best to replace these in pairs as there are a few different styles. I recommend the Optronics LED Combination Trailer Tail Lights part # TLL160RK.

  • Can LED and Incandescent Lights be Used at the Same Time on a Boat Trailer
    The issue with using LED lights like part # TLL160RK with incandescent lights is that LEDs draw much less power than incandescent lights. This can lead to inconsistent operation of the lights so it is always recommended to either have all incandescent or all LED. If your LEDs are on a different circuit then you could use these with your current clearance lights, but if they are on the same circuit then you really need to have all of your lighting stay consistent.

  • Are Optronics LED Combination Trailer Lights DOT Compliant?
    Yes, the Optronics LED Combination Trailer Tail Lights item # TLL160RK are DOT compliant. They meet the Federal Motor Vehicle Safety Standard 108 (FMVSS 108) which regulates all automotive lighting, signaling and reflective devices in the United States. You will need to check with your Virginia state DOT guidelines to see what other lighting equipment you will need. I have attached a faq link that will help to explain the other requirements that a trailer of your size has.
