Chuff,
    They tell me there is no such thing as a silly question.  Actually both.  I have checked it sitting still and with it coming down the track.  It is so dim that you can't tell it is on when it is moving unless it is right in front of you.  In fact at first I thought it was burned out.
Thanks,
Jon

Thanks, guys for the replys.  Now, could you please explain to me in simple terms where to find the resistor I need to change and what to look for.  I am a novice at this sort of stuff and really don't know where to start.
Don't want to screw it up.
Thanks,
Jon

I have a brand new Bachmann Shay with the factory installed sound system.  Everything seems to work and the sound is great.

The only problem I have is the headlight is dim and I can't figure out how to get it on bright.  I am using a digitrax dcc system.

I've been through the manual and still can't figure it out. Can you help?  Please make it simple.

Thanks,
Jon
