My 6v Honda keeps blowing dip and main beam bulbs, I,ve renewed the battery, regulator thingy and cleaned the earth points. My local bike shop told me to fit a resister in the wiring (the power feed to the switch). Does anyone know the resister rating Please, or any other ideas. TA.

I use to put a 12v bulb in it.

I know that some bikes ( most commonly crusers) often blow headlight bulbs due to vibration , so could it be that causing it ?

Make sure all the wiring behind the light is sealed and no water is getting in, that caused mine to blow. also as above vibration can do it, try to ensure all light fixtures and light securing clips etc are tight.

My cg used to blow its rear light when it was only switched onto sidelights. Never had a problem when I used the full headlights. It was something overloading the electrics (needed an extra buffer resistor), but I never bothered to fix it. I just replaced the bulb and remembered not to use my sidelights!

Sometimes starting the bike with the lights on can overload the lamps. Due to induction frequency stuff and gizmonikry.
Modern good quality lamps are not so susceptible to vibration.

Thanks for the suggestions, I renewed the whole front headlight to try and cure the problem but it still persisted, I've checked for loose connections, nuts and bolts, they're all ok. thanks for the ideas though, I'll try all and let you know if any solves the problem. cheers

Any bulb can be damaged by vibration (low pitched).

Lamps I buy and fit here in UK never fail due to vibration.

Lamps from lesser countries I have worked in do fail.

Normally due to on off cycles or vibration.

This is more or less eliminated by modern lamp design and construction using quality materials.


"Frequency Response Model
We can view the solution of a vibration problem as an input/output relation--where the force is the input and the output is the vibration. If we represent the force and vibration in the frequency domain (magnitude and phase) we can write the following relation:


H(ω) is called the frequency response function (also referred to the transfer function, but not technically as accurate) and has both a magnitude and phase component (if represented as a complex number, a real and imaginary component). The magnitude of the frequency response function (FRF) was presented earlier for the mass-spring-damper system."
