Hi guys, I have searched through the archives but cant find an answer so I thought I would ask for some help. I have an 05 HSE that I recently installed the OEM hitch wiring kit to. There are no issues with it when using my utility trailer but when I hook up my boat trailer there is all kinds of things that wig out. The dealer told me its because of the LED tights on my boat trailer and the car can not be used with these types of trailers. I am finding it very hard to believe that Rover would not have a solution for this problem and basically are telling me I have to put new lights throughout my trailer or I'm SOL. Do any of you have a solution other than this or selling the car?

Thanks for the link Ron. I sent Lee a email and he got back with me pretty quick. His shunt is for the Sport and Discovery and has yet to do anything for the HSE so at this point I'm stuck. I suppose I will have to figure it out on my own. I can't believe someone here in the states has not come up with a solution for this when you consider how many of these cars have been purchased by people that have ski type boats.

LED lights on the trailer will cause many fun things. Rapid flashers, "check trailer light" message on the info centre, when you shut the truck off and leave the trailer lights connected it will pulse the trailer lights every few seconds. I just live with it, I wish it didn't do it.

Buy a trailer module that isn't RR specific. I'm not sure why anyone would care if the trailer module showed up on the display.
I would need to look to see which one I have in my RR. When I get home I will check.

ah, this is a real drag.
I just bought a new 6X12 Cargo Trailer and had it scheduled to get it paint matched to my Rover.
But now it appears as if I will have to pull out all the lights first and replace with non LED lights.

I never thought about that.

nsxxtreme,
I would also love to know what module you use also instead of the LR branded one

Thanks for posting the link to the alternate module. I can't get the valley site to tell me anything about that part number. The valley site doesn't even acknowledge Land Rover's existence, so it is not a Range Rover specific part.

How did you wind up with that one?

How difficult was installing it? Pretty obvious with the directions that come with it, or would I need to be an electrician? Other parts I would need to order as well?

Sorry for all the questions, but looking for an alternative to the $200 LR part that I might use three times in the life of my truck.

It came installed on the truck when I bought it.

Looks fairly simple to install. I tried to find info on it as well and didn't have much luck.
The unit itself is labeled which wires are what. You just need to splice into the correct wires on your RR. Besides power and ground I think 4 more wires. All accesible from the rear fuse box area.
Its works great for me I tow my boat/motorcycles/jet skiis no problems. LED tail lights no problem.
Also has an integrated circuit breaker so when you have electrical problem it doesn't fry the unit. -> This happened on my mortorcycle trailer wires got pinched and shorted together.

I just picked up some kits from LR today, if anyone needs one let me know. I am working on figuring out how to place a resistor in the module our outside that would keep LED lights from flashing.

I'll keep you all posted.

I have bought the OEM trailer wiring kit to install on my 06 HSE. I too, have a utility trailer with LED lights (haul my golf cart to the beach, etc). I haven't installed it yet because of the postings I have read about the pulses (lack of resistance) on the LED lights.

This seems to be a common problem on imported vehicles as noted on the BMW, Mercedes, and VW forums. I came across an inexpensive solution on the VW forum that a gentelman at UHaul came up with. I emailed him and he said he is confident it will work. It appears to be a simple plug for $30.

The problem apparently with LED's is their low voltage usage. It sends a signal to the computer of the vehicle that a bulb is out...Therefore, some resistance needs to be created. Here is the link....Please comment as I have not bought this yet. I must admit, I am not very electrical savvy.

Sorry to drag up an old thread but your link no longer works. What product were you referring to?

Thanks

I wired my 2004 with the OEM trailer wiring kit, and added my own wiring for the brake controller since that was not included, see the main site at http://www.rangerovers.net/outfitting/t ... ntrol.html

I have towed out livestock traler with LED lights without major problems except for the ranom flashing of lights that I ignore!!

IF anyone finds a better solutio please email me so we can add it to the site for the benefit of others

Cheers

John

Got my wiring harness installed in my 2006 HSE. It went without a hitch but it sure didn't like my LED trailer lights. Luckily, I had the original bulb type lights which I swapped out and it is working fine. Would like to go back to the LEDs but want to find a solution for the blinking and fast turn signal issues. Interested to hear if anyone has figured this out. Find it strange with the proliferation of LED lights that LR doesn't have a way to address this officially.

Thanks

Anyone find a solution for this?

When my Range is off, the trailer LED's pulse once every 5 seconds. I think it's the Range "testing" to see if there is a bulb out. But this test micro-electrical-burst turns on the LED lights because of how efficient they are.

I can have my electronics guy wire in a couple of relays so the Brake and Turn Signal wires are "off" when the vehicle is off, but this still won't solve the issue of driving down the road with my LED lights pulsing once every 5 seconds.

HELP!!

I have a 2006 HSE and just installed the electrical harness.
Since I have a boat trailer with led lights...I received the message to check lights.
The trailer lights blink on their own, and the turn signals flash very quickly.
I checked out the LED Light Trailer Module, but it seems to be for VW and Audi.
I then called someone in the trailer business to see if he was familiar with this issue.
He did not know of an item to fix the issue on the Range Rover,
but suggested I place a regular light bulb in line and that should satisfy the computer.
My trailer (and boat) are in a paint booth now and I won't have access for a week, but
plan to try this idea.
