headlight is dim

does this mean the bulb is bad?

Depends upon many variables. Was your bike running? If so, was it idling or mid-high RPMs? What kind of headlight do you have? What's the wattage? Etc.

I dont know too much about the wattage.....the bike is running and has a brand new battery......I am assuming I have the stock headlight.....sorry I dont know too much about what I have

You will have to look into your factory service manual and see if you have a "reserve lighting device" on your bike. If so, it will run your Hi-Beam at half voltage if your Lo-Beam burns out. your owners manual may have that info also.

ok I will do that, thanks!

I'd drop the headlight(remove it) and check the voltage at the three prong socket the plugs into the headlight(at the top of the list).
