Basic headlight wiring diagram - Here is a regular socket for an h4 bulb. Your cord hues can be special, however the layout might be the same. This photo is from the back of the connector, i.E. No longer the side the bulb plugs into. Your unmarried bulb has two filaments, one for the low beam and one for the excessive beam. If you observe the returned of the headlight bulb, there may be three prongs. One is for the low beam, one is for the hello beam, and the closing is the shared floor. The low beam and hi beam want to be grew to become on and stale independently, so you need two relays.
I have motorcycle with 35 watt hs1 bulb and that i want to improve brightness of headlight so i determined to place h4 60/sixty five watt xenon bulb. An expert in this forum advised me to use relays as the brand new bulb calls for more electricity. I did some google to recognize relays and a way to wire new headlight with relays, however the confusion is that the links and films for relay wiring that i found on-line was for automobiles and automobile has two head lights in order that they have used two spdt(bosch) relay for that however for my motorcycle i need only one bulb so i wager unmarried 30 amp spdt relay might be enough but i am stressed what must be the circuit diagram for unmarried spdt relay to manipulate headlight hello-lo beam. I recognise instead of making setup from scratch by myself many of you would advise me to head for japanese beaver h4 kit however the problem is that i am in india and that i dont have any paypal account to pay for package and even no longer certain whether this kit could be inexpensive for me or no longer thats why i determined to make this setup by myself.
