Yep, seen that one.

Just trying to get the message across, it's something that doesn't seem to be sinking in with D4 owners.

Another thing, just turning the headlights on will solve the trailer LED issue, sure the trailer indicator on the dash doesn't work, is it that important.

I only asked about LEDs in the bullbar because my Defender detects them in my ARB bullbar and the trailer symbol is always illuminated, so I wondered if D4s would be different.

Are you sure your bullbar indicators are actually LED?

On my D2 the ARB bullbar was supplied with normal incandescent globes for side and indicators, my D2 saw the additional current draw from the indicators and assumed I had a trailer so flashed the dash trailer icon.

I later upgraded the bullbar lights to ARB LED ones (The same type supplied with the D4 summit bullbar) and no longer had the trailer icon when indicating. Even with my camper trailer (With LED lights) attached to the D2 the current draw of two additional LED indicators (Per side) was still not enough to illuminate the dash trailer icon. The same is true with my D4 with summit bullbar and LEDs lights. Which is why I bought a pair of load resistors and a switch, the fitting of which is on my growing list of things to do...

That's the next job I guess.

I balked at the price of the Narva one so bought a pair from eBay at a fraction of the cost. I haven’t actually fitted them yet but have measured their resistance and it was 6.8 Ohm, within 5% anyway, which works out as 21W at 12V. I know a D4 is more likely to be at 14V but assume a normal 21W incandescent globe is rated at 12V, but I’ve never actually measured the resistance of one. They came from China, so probably made from Australia aluminium and copper and took 2 or 3 weeks to arrive 2x 25W LED 6.8Ohm Load Resistor For Hyper Flash Turn Signal LED Controlle HOT | eBay

dash trailer indicator works regardless of headlights on or off as it’s from the indicator, not the headlight or drl circuit, agreed the trailer stability control is active regardless

Not on our D4, if I tow a trailer with LEDs and don't have the headlights on, the right indicator on the trailer won't work, soon as I turn the lights on it works but the trailer light on the dash stops working, for me it's not a big deal.
