Bought meself a nice shiny wee number plate light from hein gericke today to replace the POS motrax one I currently have fitted which goes mental in the rain (dunno why because it's always dry inside when I check it and all the wiring's fine...) and doesn't really suit the bike. The new one's small and very tidy and should just have been a matter of removing the old one and fitting the new one with a wee bit of wiring.
The trouble starts when you take the light out the pack and see there's only one lead coming off it

...
It looks like one of those wee LED bolt thingies but bigger with a proper bulb in.
Any ideas?
