Hi Jeff,
I have to go with Tony on the cosmetic value, certainly puts an edge on the look and Randy nailed it on best illumination at night. They actually raced on the cars lights, none of this lit up stuff we have today for the TV cameras
Here's a couple of spins on the black out theme on CAV Canada customer cars, Angelo and John's Gulf livery rockets. Interestingly enough, you can find old pics of the cars racing in 68'9 with and without blacked out lower driving lamp opennings.
On Angelos' car we painted the edges of the driving lamp covers orange as per the original.
Cheers
