<VV> Head Light Problem...

[JVHRoberts at aol.com]

1. The low beams have two filaments, one for low, one for high, so, it's  
like two bulbs in one, just like the tail/brake lights or parking/turn signals. 
2. You could simply have a burned out low beam. 
3. You could have a bad wire or terminal to that low beam, on the low beam  
only wire. Best way to check is to pull the bulb, and with it still connected,  
check with a voltmeter or 12v test light to see if the power is getting to 
the  bulb. Make sure you figure out which of the three is low beam, high beam, 
and  ground! The center one is the low beam, and the two outer terminals are 
high  beam and ground, but I am not sure which is the left and which is the 
right  terminals!  
4. Probably not the dimmer switch, since it feeds both low beams.

67 with  parking lights wired to come on with head lights.

Changed the head  light control switch about 2-months ago.  All was  fine 
until  today: have no driver's side low beam with the dimmer switch calling  
for  
low beam. When I press the dimmer switch, selecting high beams, all  four  
headlights (as would be normal for high beam selection) come  on. It would 
seem  the 
problem is not with the left side low beam, as  it does illuminate with the  
high beam selection.

Pearls of  wisdom, anyone?

Thanks,
