I have bought some LED replacement H6W bulbs to accompany my OEM Xenons, only problem is when I fit them the continually flash on and off with the same rhythm again and again.

Why the bloody hell is this?!

I thought about maybe putting a small resistor across the circuit to show the car it has a bulb in place as the LED's draw a lot less current than the 5w bulb they replace, maybe the car has some sort of dumbass sensing system?

I dont have DIS by the way.
