Thread: Disco 4 LED Towing Module Problem

The resistors also activate the flashing trailer on the dash when the indicators are used. If only 1 resistor is installed, all the functions above are activated, except the trailer light only flashes turning one way.

Thanks Tombie for this.

So I only need the 2 x indicator resistors to turn off the rear parking sensors?

Is there any reason to install resistors to any of the other light circuits?

Do any of the light circuits on the Disco 4 run pulse width modulation?

How much can I load the existing light circuits before running into "fuse blowing" problems?

Hi Peter,

Only the indicators (both sides if you want the Dash trailer light to function on both).

Each circuit will handle at least 10a

If you towed it with a normal vehicle the D4 will do it..

If the horse float has an internal light etc you could wire it to the 12S plug and have Aux power...

Let me know what you're looking to do etc and we can easily work it out..

The D4 has separate tail light and brake light circuits, so doesn't use PWM to dim the LEDs like other European vehicles (or even my Korean motorcycle!).

I know that this would be irrelevant to the current trailer socket discussion but I thought the front DRL LEDs used PWM to dim when either the headlights or indicator are on? (The strip LED version since MY14)
