Just one very quick question guy's anyone know which wires from an aftermarket replacement headlight ( green and yelow wires coming off it ) are positive and negative. I don't want to burn out the bulb by wiring it wrong. Thanks in advance

Hi Alan,

If it's a bulb (not an LED) then there's no polarity issue.

If it's an LED, then it can't be blown by reverse fitting BUT it CAN be blown by the _correct_ polarity if there is no current limiting resistor in series with it. All different colour LEDs have a different working voltage, but if you put a ~270 Ohm resistor in series (either wire, it doesn't matter) you should be able to drive it from any typical electronics we encounter in the HL tanks.

Thank you Nige. Will have to pop into town and get a resistor. All the best for now
