All went well except the ground wire was short on the trailer harness, had to splice a piece in. Manufacture should consider making it another 12-18 inches longer.

Well the connectors on the wiring looked ok and it had wiring to install to a vehicle, but there are some deficits. Sold as a premium, but does not come with clearance lights (even many small trailers have at the front. ) I bought it because i thought submersible led lights meant it would be very good quality and low long term maintenance. Evidence is not promising! Instructions: there were none. There was a link for video instructions that just told how to install the lights . Two bolts and wire nuts. Pretty simple! Unfortunately, no instructions were included with the clips in the wiring harness box. The clips were very small to hold wires in place, some i couldn’t figure out. My trailer is simple; however, so threading the wiring in place of existing wires, and switching out the light fixtures was pretty straightforward. After threading the harness, when I was stripping the wires leading to the lights, I realized the wires were only 18 gauge. (The wire pigtails on the lights were 16 gauge.) Normally i like to have wiring leading to a fixture thicker or heavier gauge than the wires in the fixtures. The ground wire was only 2 feet long from the plug. There was nothing that close in my trailer to connect it to, so i needed to use my old ground and attach to that wire. When it was all connected, the driver side light had a short in it. ( that light did not work and the wires leading do it became hot in less than a minute.)

Had problems for years with OEM incandescent trailer lighting shorting out the vehicle’s trailer light converter on multiple occasions. Finally performed a thorough troubleshoot which included replacing wiring and lighting. etrailer is a great resource for tech support & troubleshooting. Decided to upgrade w/ LED lights since they are brighter and amperage requirements are significantly lower. In the process, I discovered a broken ground wire inside of plastic conduit close to the trailer plug. Repaired the ground wire and checked all existing wiring for continuity. Satisfied that I corrected the problem, I decided to keep the existing wiring in place and installed the new LED lights. Stripped and connected wires with a butt connector and heat shrink tubing. Ground the paint off the light mounting stud locations to ensure clean metal was exposed for the lamp ground wire. All is now in working order. Note that I decided to continue using the incandescent clearance lights on the front of the trailer since their amperage draw is much lower. Typical recommendation is to not mix the two types of lighting due to different amperage requirements. Unfortunately, I could not locate a complete kit which also included LED clearance lights.

The product is exactly what was listed on the website and the quality is great. I looked at Walmart, a local marina and a local part store for trailer lights. These lights I got from etrailer.com are better quality and a better price including shipping. It was delivered faster than expected. I was so pleased, I purchased more product from etrailer the next day.

Love the lights. I would give them five stars all day long. The wiring harness is a bit chintzy. More like 2.5 stars. It feels like if the manufacturer spent another .02 on it the quality would be better. If you paint your trailer, you need to grind away the paint beneath the ground wire, otherwise they will not work.

I purchased a 40 year old galvanized boat trailer from a local Salvage Yard and it had bad wiring and sun damaged plastic light boxes. This light kit from etrailer worked great. Bolt holes lined up and installation was very fast. All lights worked correctly on the first hookup. License plate holder is made for standard size tags and Montana uses smaller motorcycle size. Drilling new hole will be necessary.

These lights are really sharp. LEDs are nice and bright and should be better than my original set. Installation was not difficult. For connecting to the wire harness, I used waterproof, heat shrinkable butt connectors I got from an auto store, as the twist connectors that came with the lights are not really suitable for boat trailers. The enclosed three way Scotchlok connectors made it real easy to wire in my side marker lights. Look forward to many years of ware with this set.


Comments
The products are working just fine.
Paul P - 12/12/2017

Over all the set is a complete package. In my opinion, there is one point that I would like bring to others attention, that is while there is more than enough wire for the lights, the ground wire pig tail for the vehicle and trailer end is too short and in most cases will require one to splice in an additional piece. There is a 16" pig tail on both the vehicle and trailer connectors, thus if you are wiring the trailer for a car, your ground wire on the car side will be too short. If you are wiring the trailer to be towed by a truck the ground wire will likewise be too short on the trailer side. If the manufacture made both ground wire pig tails the same length as the vehicle wires, that would solve this issue.

I am disappointed. I received the trailer light kit (TLL9RK) today and looked over. I thought I was buying a submersible pair of lights. It is described as submersible on your website, but does not appear to be submersible. There is a large hole on the back of each lamp housing through which wires pass. The first time it is submerged water would flood the lamp housing and reach the LEDs. Each lamp housing has short wires passing though these holes and the user must make the connection to the cable with electricians twist nuts, scarcely a water proof connection. The kit is sold to you by Optronics and is called "waterproof" on their packaging. Is that supposed to be submersible? Rain proof maybe, which useless for a boat trailer used for launching a boat down a ramp. I believe this tail light pair would short circuit the first time it was submerged during a launch, and possibly blow the fuses for my cars tail lights.


Comments
These lamps are indeed submersible, the LED assemblies inside the lamp are completely sealed. Ive used these lamps on my PWC trailer for several years, and they still work perfectly. Instead of using the wire nuts, I would recommend soldering the connections and protecting them with heat shrink tubing.

I was very much surprised that the hardware was stainless steel, which is great for salt water trailer usage. I was disappointed that the wiring harness was light weight wire, I would guess 20 gauge, but it should be sufficient for led lights. All in all I would purchase this again.


Comments
I received an e-mail requesting how I rate these trailer lights after one year of use. I have had them on my trailer over one year. These lights go under salt water each time I put my boat in the water - they are working just fine after more than a year. I would purchase these lights again.

After a year lights are still bright, lens clear and waterproof. Easy to install and had clear instructions. I bought waterproof connectors and used a heat gun to install them on all connections as I put these not only on my utility trailer but my boat trailer as well. A qaulity product for a good price, and excellant customer service. I would def buy these again.

I purchased this kit to replace the existing setup on my 4' x 8' utility trailer that had served me well for about 15 years. I was having problems with blown fuses when I turned the vehicle headlights on, and then when I used the turn signals as well. It was pretty clear that my problems were coming from the old light fixtures, but I decided to go ahead and replace the whole wiring harness at the same time since the extra expense was nearly insignificant. This kit came with almost everything needed to complete the job. I added some 1/4" corrugated wire wrap to help protect the wires from abrasion, and a few waterproof heat shrink tubes to seal the connections (2 for each light, & 1 for the ground wire). I chose to solder my connections and then seal them with the waterproof heat shrink tubes. There was enough room inside the light fixtures to enclose the connections and keep them out of the weather. The whole process of removing the old lights and wiring, and then installing the new components took about two hours of leisurely work in the back yard. It was an easy process, and the new lights are much brighter and more reliable now. No more blown fuses. They have the added advantage of drawing very few amps as compared to my old incandescent fixtures. I think it was well worth the little extra cash to invest in the LED lights. The kit included a flat 4 wiring harness to connect to the vehicle, which made my neighbor happy when I gave it to him - my truck was already wired for a 4 flat connection. In all, this was the most recent of my 3 or 4 purchases from etrailer.com, and I will certainly be back for more. The prices are good, shipping is fast, and there is wealth of instructional information to consume.

Bought this product to replace my incandescent lights on my boat trailer with led lights. Price was right. I have not installed them yet but I'm sure they will work fine as with anything I've purchased from etrailer so far.

I installed the Led Lights on my Trailer and they work Great.. The led lights are much brighter then the incandescent lights. I placed my lights on the back of the trailer where they do not get submerged when ping off my 17 FT Boston Whaler.. I do not need the back my trailer in the water all the way.. I usually back the trailer where the water is just below the hub bearing..Will definitely recommend this trailer light kit to anyone looking to replace their lights led lights and wiring.

After struggling with corroded connections on the original lights, it's was time to redo them from one end to the other on my utility trailer. This kit did the trick! Bright lamps! No more faulty contacts or replacing bulbs! Clean wiring throughout! Tip: Squirt some silicone or RTV in the crimp connectors for a water tight seal. The only CON is that there weren't really enough stainless wire clips to keep everything right sms tidy. Fortunately, I had some add'l ones. I'll bet if you asked George, he'd send some more!

I installed the Trailer Light Kit this past weekend on my motorcycle/utility trailer. The good: the lights themselves seem to be of good quality and are quite bright, just what I was looking for as replacements for my existing lights. Also, the wiring seemed fine as well. The 'bad': The hardware that came with the kit was pretty much useless. It came with some miniscule wire nuts which I found rather odd since the lights in this kit are 'submersible'. I bought some butt connectors- weather proof with heat shrink covers instead from an autoparts store. Also the clips that came with the hardware could only be used on a trailer made with angle metal as they push onto one side of the angle. My trailer is made from square tubing so I had to procure loom cushion clamps that utilize a screw to attach to the tubing. Loom clamps would work on either so I would suggest they be included in the hardware kit. I would have given the kit a 5 had the hardware been decent as the wiring and lights seem fine.

While I am very pleased with the product I must note than when I plugged in the newly wired trailer to my truck, nothing worked. OOPS! But since I have wired trailers before and knew that ground wires were extremely important, I hooked up the ground wire to both lights and everything worked perfectly. I mention this because the directions said to ignore the light ground wires because they are grounded internally----NOT. Love this product

  • Do I Need LED Resistors When Switching to LED Lights on My Boat Trailer
    You don't always need to add a resistor like the Putco # P230004A-2 when you're swapping your trailer lights over to LED's like the # TLL9RK. The best way to determine if you do is to install the lights and then see if you get hyperflashing when those circuits are activated. This keeps you from buying and installing parts you don't need. There really isn't an exact science to what situations will call for this and it really varies from vehicle to vehicle.
