 When I went out to the car last night at the Club meeting, I had exactly the

 same problem.   I wonder what we'll find?

Two possible sources that I can think of:  

1)  Stone chip --the obvious one 

2) For Euro/Aero factory flush mounted headlights.  Blocked headlight vent
hole(s).  Hard to see unless you remove the headlight lens assembly.  On my
V8Q, for example, there is an upper vent at the inner headlight housing and
lower vent at the outer side.  Also, there are rubber boots attached that
angle downward, presumably to prevent water from directly entering the
headlight.  If you have the headlight out, remove the rubber boots and check
for blockage.  I found that some of the chromed plastic for the reflector on
the pass. side had not been suffiently cleared before assembly, so I used a
knife to bring it to its rightful size.  These vent holes serve to keep the
humity factor equal between the inside and outside of the lens.
