Huge lot of 50 industrial pilot indicator lights for control panels in yellow, orange & red

Large lot of about 40 assorted industrial panel status indicator and pilot lights. These lights are marked "Dial Co - NY" and "75W 125V". These lights measure about 2 inches long and 5/8" across and 1/2" high on the colored lamp globe. One of the terminals is stamped with a positive symbol "+" and the other terminal is unmarked. The globes are plastic and unscrew to reveal the light bulbs. 

There are about 23 yellow, 19 orange and 8 red lights.

These indicator lights are all from the estate of an electrical engineer / industrial control integrator and many have solder on the terminals where they seem to be recycled and reclaimed from other projects.
