my 78 sachs westlake keeps blowing the headlight. when it happens the tail light and speedometer light all go out as well. any idea why this is happening?

does it have a battery---something's letting too much power through-- unless vibration is doing it,
fuse it, at least you'll cook a fuse before an expensive headlight.
Gah, I played and played with the circuit to my peugeot for weeks this summer. First off, the speedometer and taillight are in series with the headlight, so if it blows then none light up cause none are getting power. Second, if it keeps happening, make sure you have the correct voltage and wattage on all bulbs in the circuit. The crazy magneto setup makes little or no sense to me: I just know that it demands having the factory determined wattages and voltages. If the taillight is wrong it may cause the headlight to burn too quick and hot or whatnot. Watch the amps. And yeah, a fuse would be a killer idea: of course it depends on what kind of power source you use what kind of fuse you get. Battery is dc, coil is ac, but if it is ac you still may have a regulator making it dc. Oh boy. This is what I discovered this summer. Fuse the thing though: a fuse is much much much easier to find that a 6 volt 22 watt bulb.
there is no battery on this one. i should also mention that i replaced the headlight with a 6V 30W light for a tractor or something and it doesn't blow even when there is no speedometer light, but it is too dim to even rid with at night. when i put in the correct bulb without the speedometer light it blows the headlight and tail light really quickly.
I had good luck for a while with mine- I put the correct 5 watt 6 volt bulb in the back, and a 12 volt bulb on the speedo. It worked OK. The headlight was always a little dim, but wouldn't blow. I'd recomend taking apart and cleaning your switch, and making sure it goes back together right.
