I have done the conversion suggested on my classic its brilliant ,the light are now superb BUT its only a small but ,you will find theres a lot more power going through the dipswitch ,after a while the springs go in the switch!!!!new switch needed...however if while you are on you should fit a couple of relays in the wires to the headlights,you can buy em in pairs on a bracket,find the wires coming from the dswitch to the high and low beams and cut them wire them up to the relays at one side supply power to the other side and use the wires from the dipswitch to trigger the relays ,now you have very little power going thro the switch,the relays take the strain ,,,simples...ps dont forget to earth the relays or they wont work.....hope this helps ..dave
