60-66 cab lights...

[jocko]

Always thought of these as dealer options that a buyer could order. The 66 data book lists them as "Custom Features (Dealer Installed)". But this picture seems to make one wonder... If they're on a smattering of assembly line trucks, then that doesn't seem like a dealer add-on, now does it? Thoughts? I know there were no factory guide lights like the 67-72 era (with roof pads), but always thought they yankee style were dealer only. This style is kinda growin on me....
