more headlight issues

I keep blowing low beam on my headlight. Hi beam works everytime, just the low keeps going. I got to replace it evry year, last year twice. could it be that im just buying bad lights? This time when it went, I was in the garage, and noticed when I reved it, the light beam would viberate badly, then went out. Is a car light, and a motorcycle light different? What do you guys think? thanks

A car light is different from a bike light. I know one difference is in the pattern of the cuts in the lens. Cars are designed to have two lights, bike have one, and the patterns are different because of it.

Do you use car sealed beam units? If so, I would suggest looking in JC Whitney for their mototcycle light upgrade to H4 halogen. You can also find heavy duty H4 bulbs in any auto store / walmart. Maybe that's what you need is a heavy duty bulb.

Vibration will kill a sealed beam light!! try to stop the shaking ( if it does) or go to H-4 hallogen

no the low beam is different wire than high beam and is prone to the vib.
