Thread: Discovery 3 LED trailer lights

All modern vehicles have this issue with LEDs on trailers, not just Land Rover, Prado, 200 series, the new Y62 Patrol, VW, BMW and the list goes on, from what I've heard.

AND at the risk of reposting, look at this everyone.

Baz, no issue with leds on trailers with the 200. Best mates perfectly fine with his 3 led fitted trailers.

I had a problem about 5 years ago with my Touareg....software written to fix that, and since then no issues at all.

It can be fixed but obviously not a priority for LR to do so.

Some bloke on another forum was whinging about his Prado and he mentioned his mate with a 200 had the same issue, maybe the early ones had the issue and Toyota fixed it.

It's not a big deal on the D4 really, I've towed a trailer with LEDs, just turned the headlights on and all good, I don't have to worry about parking sensors, we had ours turned off and the trailer symbol not working is no big deal.

Sorry if it was stated before but i didnt read that whole huge thread but there is a simple and quite cheap fix for that problem now: NARVA LED Load Resistor 12V 21W - Supercheap Auto Australia

If you had read the thread you would know that a simple resistor doesn't fix the issue. The trailer lights will still flicker/flash like a christmas tree

I apologise that i didnt read it all but it fixed the issue on my D2, my brother's RRS and a friend's D3(no D4's around me), so did for the guy at page 24 post #232 too... also i can't imagine why a dedicated and especially calibrated resistor wouldn't fix it as long as it emulates the bulb which was there, for the system it's a simple current draw issue and the current with that resistor is the same like with the original bulb... there might be some exceptions but IMO on those the problem is something else

D4
A simple 10-15$ resistor wired in parallel with a single LED indicator light on the trailer will fix all issues.

D3
The simple resister fix will address some of the issues but is not a complete fix. A 'pulse buster' or similar device involving relays is required.

Do we really need another thread on this?

hi all,

really struggling with the wiring diagrams and trying to connect the two led resistors and two relays with wiring on trailer but cannot seem to work it out. is the ground pin 85 white wire the earth ?

i have a 4 pin relay, 87 pin to led lights, not sure how to use 86 and 30 up. 86 is switch and 30 + battery but which colours are these on the typical trailer wires, there is no + battery or switch wire is there ?

spent good amount of time on these and cannot get it to work, to suit D3.
Any help much appreciated. thx

OK, gotta ask as Im a klutz. When wiring the Narva LED load resistor, I connect one end to either indicator wire and the other end to earth to create a parallel circuit?

Correct!

Just bought one of these last night. I am trying to avoid paying $180 on eBay for the plug set up. I didn't tick the LED box when ordering my trailer but it still came with LEDs.
