Evening all

I am about to wire up the lights and will be using a combined stop tail bulb. Does it matter which element does which? If so which is which?

Cheers

Yes, 1 element will be 5or10 watt (tail) and the other will be a circa 30w for the stop. Im not sure of there is standard but it should be easy enough to tell by just lighting them up and seeing which is brighter.

Ok thanks.

The bright one (21w) is the stop. If you wire it the wrong way you would have bright side lights that you wouldn't be able to see the brake light. Not sure which terminal is which but a bit of wire and a battery will soon tell you.
