Ok so i was driving home lastnight and my headlight started flashing on and off then all the sudden they just went out, once i got home i turned the bike off and tryed to start it up the button isnt work and my headlights arent on.
do i need a new kill/start switch or is it something else?
If those check out ok - check to make sure power is getting to the fuses and connectors and the start switch. You will need a multimeter, simple tools, and about 15 minutes.
key is turned fuses are good the kill/start switch is getting power cause the fuel pump still kicks on. the button use to cause my headlights to flicker on and off and finaly it has just gone out all together no lights and the button wont work
had no idea the headlights were connected to the kill switch or start button...on any bike.
if the switch housing that has our hi/lo beam selector on it is not working, take it apart and inspect it. You may find you have to clean the copper plate inside or a solder point has come loose.
Whenever I have seen this in the past it was due to the charging system going bad. When this happened the bike would run straight off the battery until the battery went dead. Before the headlight went out, with many bikes you could tell because if the charging system was working (if you look closely) you could see the jump in power in the light when you would rev the throttle from idle. When the charging system fail you would not see this at all, just a fading out, then no light, then the bike stops.
If your bike's charging system is running, once it is started, you could disengage the battery and the bike's charging system will close the loop, as if the battery was still connected.
Once it is started and running, if you dis connect the battery and the bike stops, your bike's charging system may need to be replaced.
I have used a car battery (car engine off or disconnected) to jump start a bike and give a little "oomph" to the bike's battery, if it is not completely drained with no problems.... I am NOT telling anyone to do this, however.
I am not telling you what to do, just my thoughts on it.
I don't know if this helps, but that's my idea.

the high-low beam switch works fine its the right side start button when i press it nothing happens. the button and my headlights both went out at the same time, use to start button would cause my lights to flicker not due to powerloss when i press the button in to start it the lights go out for a split second untill i let off the button and the bike starts. now when i try and start it the button does nothing and my lights are still out do i need to get a new right switch to fix this? also the bike did not stop or die i still have power the fuel pump works blinkers tail lights etc. just not my start button or headlights

I think he got it the first time! Freaking wacky site, I think Moto Bro fucked it all up. Either try to clean the contacts, check for loose wires in switch, or replace it.
You seemed to say that both the high and low beam started flashing on/off and them went out. What about the console backlight? If it was flashing too, the B/W ground at the connector in the left cowl might be bad. If only both headlights were flashing, the problem is probably in the power to the lights. Turn the ignition on and measure the voltage at the Horn/Brake and Ignition fuses. If the voltage is zero (or low) either the ignition switch is bad or it's not getting power. If it's +12, measure the voltage at the headlamp fuses. If it's zero, there's a problem with the Start switch or the associated wiring.
DUde its your kill switch take off the red cover and clean the connection I had the same problem. the connection just needs a little sand paper and make sure you gently pry the connection point.
My bike is doing the same thing. I've traced it to the starter switch as well. I'll probably try cleaning it this weekend. Right now I have a jumper wire in the fusebox so I have lights.
What NOS says makes sense as the starter switch cuts power to all of the various lights while the bike is cranking. A jumper from the top (I think) of either the Horn/Brake or Ignition fuse to the top (I again think) of either headlight switch will bypass the switch but the bike will probably crank a bit weaker as the lights will stay on. The real solution is to take the switch apart and clean the contacts but cycling the switch a bunch of times with the ignition switch off may be enough to get it to work for a while.
Yeah Bill right now my lights don't turn off when I start the bike but it doesn't crank any slower than normal as far as I can tell. I still have the original battery in my bike as well.
I tore mine all apart today. The starter switch assembly is ok. The issue is with the plug on the end of it. It sits right on top of the valve cover and because I ride my bike in the rain water gets up there and corrodes the connection. Suzuki doesn't use a sealed plug so water is able to get into it from the backside. Cleaned the connection and it works for now. I left the small jumperwire loose in the fusebox so I can hotwire it in an emergency if I need to.
