Hi,

With negative earth it’s easier. Seems for positive earth a caravan relay may help you.

You could always get a negative earth flasher, fitting it completely isolated from the vehicle, allowing it to be on a positive earth vehicle.

thanks for the suggestions

Some Lucas are both polarities - the one on my positive earth landrover is, but it is only 47 watts

I'll keep looking

many thanks
