Bet you have a 2 -- 1 light switch as well (extra wire) good luck finding another if its faulty ! cost me £70 once I found one NOS, Looks like some one has shifted the coil up there and deleted the big green ressistor which would be fitted the other side? Prob has a Carrello head light too !

Well im no train spotter and it doesn't look like its ever been apart. All new parts will be BGM so no use to us with this resistor. ill put the photos on tomorrow showing the forks. hub. And wide wheels. Ps yes it is a ...Carrello head light
