Really cheap.
These lights are marketed as submersible, but based on what's in the package I'm really dubious.
The lens bodies are not sealed. As you can see My photo, each lens body has a clearance hole for the wire - No gasket, and plenty of room around the wire, So water will definitely flood in and submerge the contacts and bulb/socket If you put these on a boat trailer.
Additionally, to Make the wire connections. They give you wire nuts. For submersible wire connections, at the very least, you should use crimp butts wrapped in tape - or better yet a heat shrink crimp butt. But they give you wire nuts, which aren't even really stable against vibration, let alone moisture.
It does say 3-year warranty on the package, however, so I guess I'll be testing that out.

Put these on an old boat trailer. Came out great. I got some white 16 gage stranded wire to carry the ground out to each mounting place. Helps the lights stay on even when stuff gets rusty.

The light kit works great now; however, after much sweat & experimenting. Initially, I couldn’t get any of the lights to work, then I sanded away the paint where the lights attached to get good grounds from each light bolt/screw. At that point, 1 light worked perfect while the rest remained very dim. After changing wires & tow vehicles to verify it wasn’t something wrong with that connection, I found an etrailer post about running separate ground wires from each light directly to the ground connection coming from the tow vehicle. After another run to Lowe’s & several more feet of wire - it worked. Finally!! I don’t deal with this stuff regularly so this was like looking for an electric needle in a haystack. During this process, I called etrailer & they were good enough to get ready to send me a replacement light set, thinking this one was defective. Fortunately, I didn’t need it.

This is a pretty standard trailer light package. The price was good and the equipment works great. I would recommend this product. It comes with electrical clips that are garbage though so I would recommend doing something different for you connection health. Overall, I have saved it for the next time my tire explodes going down the road and takes out my lights just for added injury to my night. (lol)

Ok, had an issue with the bulb socket for brake and turn signal. Those socket designs date back to the stone age. Hard to set the bulb for proper electrical contact. Badly needs an updated design.
by: Steve08/16/2021
This is an excellent product and simple to install. As long as you have a functioning plug-in on your vehicle you’ll be happy.
Time will tell how well it holds up to water and vibration

I’ve since pulled my boat to the lake with the trailer that I installed this lighting harness on. I unplug the lights before I back down the boat ramp to assure I don’t short out the system. Other than that I am still satisfied and would recommend these to anyone. Simple to install

Easy installation, works the way it sho uld.
by: Steven 03/10/2023
The quality of these are better than the factory lights that came on the trailer originally. They're even brighter even though they use the same kind of bulbs as the original factory lights. The price was reasonable too.
by: Jacob 11/25/2023
Work great and good price
by: Dan12/09/2022
Great kit! Includes front marker lights, splice connectors, wire support clips. Just about everything. The only things missing would be red splice connectors for tying in the taillights. Just a suggestion, it would be great if the ground wire was a little longer, and a bigger eyelet for the ground.
by: Edward 05/06/2023
Have not yet installed the lights but the system is complete well built.

Thanks ETrailer for making my boat trailer restoration a success . I restored a 1960 boat trailer to look brand new with your help.
by: john c09/23/2017
The lighting system performed well in traveling from NY to northern Michigan and return to carry an old boat back for restoration.
by: Michael 12/19/2022
Trailer lights worked out great. Thanks for great products. I will definitely buy from etrailer again.
by: Adam10/02/2022
I replaced old broken trailer lights and wiring with this kit. Had everything needed to complete the task. Lights were exact fit for old lights. Everything went smoothly
by: Les 08/13/2022
I wanted the LED trailer light set, however it was out of stock and eTrailer offered this as a lower priced substitute. It serves the purpose and bulb grease has kept the bulbs working, occasionally, since I have not used the trailer very often.

I was looking for something cost efficient and good quality and I found it. I put the lights on a 62 Willys pick up I'm renovating. Work perfectly !
by: Jerry 11/05/2022
Not much to comment on because I haven't even opened the package but I installed one of the same kits on another trailer and it's hels up and works great.
by: Richard09/24/2018
I had to replace the lights on my utility trailer. The Kit came complete with easy to follow directions. Everything matched up perfectly almost plug and play. It took about 3 hours to remove the old lights and install the new ones. The only extra thing I had to purchase was extra white ground wire. The length that came with the kit was a little short. All other wire was more than ample length. That is why it got 4 stars other than that minor thing it would have gotten 5 stars. I am not a big user but the people at e-trailer are professionals with great follow up. This is the 2nd time that I used them and I do not hesitate to recommend the company and people.

- Difference Between Trailer Taillight Kits that are for Over 80 inches in Width and Under 80 inchesThere are different taillight requirements for trailers that are over 80 inches in width vs. ones that aren't over 80 inches in width. If you check out the link I attached you will see all of these differenced highlighted. The over 80 inch kits like the part # TL16RK typically come with additional clearance lights when compared to the under 80 kits like the # TL5RK. I attached review videos for both kits for you to check out.
view full answer... - Troubleshooting Boat Trailer Lights That Don't Work When Vehicle Headlights Are Turned OnIt sounds like what you're describing could be an issue with the ground wire on the trailer-either a short or an insufficient connection. This is a common cause of lights working initially but then malfunctioning when another load is added to the mix. I would start with checking the ground wire on the trailer to make sure that it is firmly connected to a paint and corrosion free spot on the trailer; it would also be worth checking the ground wire on your vehicle's wiring harness at this...
view full answer... - How to the Lights in Trailer Light Kit TL5RK Ground to the TrailerThe lights included with light kit # TL5RK ground through the mounting studs. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt the ground. Running jumper wires from the light grounds to the main trailer connector ground can help. It does sound like a weak ground connection....
view full answer... - Type of Wiring Harness that Comes with the Optronics Submersible Trailer Light Kit # TL5RKThe wiring harness that comes with the Optronics Submersible Trailer Light Kit, # TL5RK, is a wishbone wiring harness meaning there are 5 wires coming out of the back of the 4-pole flat connector. You will have one white wire for the ground, one yellow wire for the left turn and brake signals, one green wire for the right turn and brake signals and two brown wires for the tail lights. The reason there are two brown wires for the tail lights is to make it easier for you to run the wires...
view full answer... - Troubleshooting Trailer Brake Lights that Work IntermittentlySince they work then stop working most likely you have dirty pins on your trailer connectors which is causing the connection to be intermittent. Since it's both sides of the trailer it's probably the ground circuit. Your generation of Chevy truck is notorious for the third brake light fuse going out. You might check under the hood to verify if that circuit is solid still.
view full answer... - Troubleshooting Running Light Circuit Not Working On Right Side of TrailerThe blinker/brake lights are carried on one circuit and the running lights are on a totally different one. Since the stop/turn circuits seem to work on the left side but the running lights on that side do not you need to check the wiring of the running light circuit that runs to that side of the trailer and fix as needed. I attached a diagram of how a trailer is normally wired as well as a help article that covers troubleshooting trailer wiring as well.

- What is the Wire Gauge on the 4-Way Wiring Harness for Optronics Trailer Light Kit # TL5RKI measured the wire gauge on the Optronics light kit # TL5RK and the wires are 18 gauge. This is measured on just the copper strands with the insulation stripped off.
view full answer... - What Is Wire Gauge For Optronics Submersible Under 80 inch Trailer Light Kit # TL5RKThe Trailer Light Kit # TL5RK wiring is 18 gauge. This kit includes 2 stud-mount tail lights, 2 amber side marker lights, and the mounting hardware.
view full answer... - Is Submersible, Under 80" Trailer Light Kit # TL5RK Sealed from WaterWhile the wires and portions of the internals of the Submersible, Under 80" Trailer Light Kit # TL5RK are exposed to water when the ligth is submerged all of the important parts of the light and circuits are sealed so nothing gets damaged. So the water will fill in the assembly but then drain out without damage.

view full answer... - Recommended Trailer Tail Light Wiring Kit for Trailer Under 80" WideThe Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness part # TL5RK is my recommendation for a trailer wiring tail light kit for trailers under 80" wide. It comes with taillights, wiring harness, license plate holder, and amber side marker lights.
view full answer... - Trailer Wiring Recommendation for a Trailer Less than 80 inches Towed by a 1992 Ford ExplorerThe Optronics Trailer Light kit # TL5RK that you referenced would be an excellent choice for you and would work very well on your trailer towed by your 1992 Ford Explorer with the only exception is that the wiring is 18 gauge instead of 16 gauge like you said you preferred. I can assure you though that this wiring kit will work well for you and the amperage draw would not be too much for the wiring.

- Both Portable Lights Flash On Tow Vehicle When Hooked Up to RVIt sounds like you are using magnetic lights like part # TL21RK on your towed vehicle that has a 4-pin that connects to a 7 to 4 pin connector at the RV. I recommend to check all of the wiring for frays or damaged wiring to make sure there is not a short that is allowing 2 functions to get a signal at the same time so the magnetic lights light up at the same time. What type of adapter are you using and did you use it before this started happening? It makes me think the problem is a short...
view full answer... - Right Side Trailer Lights Do Not Work with Vehicle Head Lights OnThis sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt...
view full answer... - Troubleshooting Trailer Lights that All Come On When Key Is Turned OnThe issue you are having is the circuit you chose to power the running lights circuit of your trailer 7-way. If that circuit sees voltage when the key is turned on and your trailer is connected then all of the trailer lights will illuminate when the key is turned on. You need to find a circuit that only sees voltage when the running lights/head lights are on to run to the brown wire. The running light circuit of your truck should work well. I attached a couple help articles on trailer...
view full answer... - Will Optronics Trailer Taillight Kit part # TL5RK Wiring Last Longer Than Two YearsThat is really unusual for the wiring to basically just destroy itself within two years, but sorry to hear that. The kits we offer like the Submersible, Under 80" Trailer Light Kit # TL5RK that you referenced would not have this issue and would work really great long term. We have sold more of these kits than we can count and have not ever heard of that issue.

Just to make sure, I also measure the Optronics Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK the same way, and they measure exactly the same, unfortunately. With that said, I may have another option available, but the lights will be completely different. If you look at the Optronics Trailer Light Kit # TL16RK, which technically is for trailers...

- What is the Correct Wiring Needed to Re-Do Lighting on Trailer?The correct kit for your Shoreland'r PWC trailer is going to depend on its width. If it is over 80 inches wide, you will want the Over 80-Inch Trailer Light Kit, # TL16RK. If the trailer is less than 80 inches wide, you will want to go with the Submersible, Under 80-Inch Trailer Light Kit, # TL5RK. Each kit is going to come with tail lights, side marker and clearance lights, a wiring harness with 4-way connector as well as the mounting hardware. To make things easier on yourself, you may...
view full answer... - How do Tail Lights in Submersible Trailer Tail Light Kit Secure to TrailerThe Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK has mounting studs, nuts included, that are 2 inches on center for mounting to a metal mounting bracket. The bracket must be attached securely to the trailer frame because the lights in this kit get their ground connection through the mounting studs. I have included an installation video and a video review of this light kit for you to check out as well.
view full answer... - Troubleshooting Utility Trailer Lights That Dont Work with New Trailer WiringIf you are getting the correct lights with the Hopkins # 47345 tester on your tow vehicle and you have rewired the lights on your trailer then the problem is likely a bad ground just as you noted. Check all of the ground on your trailer and vehicle. Be sure that they are securely connected to a clean, bare-metal surface as even some paint can cause issues. Since the adapter that you use had LED lights for the testing it is possible that the problem is on your vehicle. LED lights use up...

A little bit of dielectric grease like part # 11755 would help prevent future corrosion if applied to the contact points. I attached an FAQ on dielectric grease for you to check out as well.
