[Raph]

Hello everybody!!

I live in Brazil, and I've a Suzuki GS500E. I want to change the headlitgh, uising 2 headlights, Busa or GSX-R 1000 one. But this bike use H4 lamp, and the models that I want use 2 diferent lamps. I know, in USA have a GS500F, and this model use 2 lamps in headlight. The question is: when we use high bream in this bike, the 2 lamps are ON? If no, I'll need to modificate the bike eletric system. Can I have some problem of batery??? I waiting for a help. Thank you very much!
