Caravan Indicators Flickering When Plugged In

[Saitch]

As stated, the indicators are strobing when the van is plugged to the Disco. They still work properly otherwise. Do I need some resistors or something to lessen current?

If the van has led lights they will strobe. Also the Disco will not detect "towing mod" and will not indicate on the dash. There are a range of features activated when a trailer is detected
The leds dont draw enough current and a dummy resistor is required. The overcome the the strobing a relay is also required
You can buy a pulse buster or make your own. I posted a design by Colin Pederson on here. That is what I used the build one for my RRS
I will try and find the old post link
