I'm glad everyone here confirms what I was thinking. The only component left out of my system is the load resistor, Narva have this one Narva |
12 VOLT 21 WATT L.E.D LOAD RESISTOR
That's the next job I guess.

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...
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 [bigwhistle] and took 2 or 3 weeks to arrive 2x 25W LED 6.8Ohm Load Resistor For Hyper Flash Turn Signal LED Controlle HOT | eBay
Just looked at the eBay ones compared to Narva. The Narva site says they must be mounted to metal as they can reach 170c and will melt plastics, carpet etc. They have an aluminium heat sink for that reason. The Chinese ones are all plastic.
