If I recall correctly....
484 had a pair of Pyle National switches, one for each headlight, set up (from front to back) as Bright, Off, Dim.
488 had the same.
487 had a sexy "all in one" Pyle National switch set up in this order (front to back): Dim Front, Bright Front, Off, Bright Rear, Dim Rear.
489 had two basic knife switches set up like 484. I always figured 489 had those funky things because it got a new cab after the 1926 wreck.
497 had an other sexy "all in one" the D&S put it in. It had an added switch that if you flipped it, the opposite light from the direction you had selected would show dim (like "bright forward, dim back"
463 basic knife switches.
I have no idea what is in them now.
Now, don't ask me how I can remember such useless stuff....
