Personally I think the Quad headlight conversion is the best aftermarket solution. You do have to cut the headlight buckets so not easily returned to stock, but the conversion doesn't require any paint work. It improves both the lighting and the look as the headlight buckets now raise to about level with the road, losing the 'frog eye' look.
Versions are available from Kirk Evans, Ted Mitchell and more recently www.saccrestorations.net or some people have even done their own.
