Blue Headlights?

[The Bedford Boys]

The blue headlights aren't bad to drive with at night. I've driven a carrier at night with clear lenses and I could see better when I turned them off! My understanding is that in NZ at least they started off making them with blue lenses and by the end of production weren't putting the blue film in between the two glasses that make up the lense. This may have been due to lack of material to make the blue part, or they deemed it unnecessary for some reason. The blue definitely makes for a better light to drive at night with.
