TINY BULB ILLUMINATES POLICE BADGE AT NIGHT

So that railroad police assigned to yard duty may readily identify themselves after dark, an illuminated badge has been introduced. Flash-light cells mounted on the back of the badge provide current to light a small bulb when the user presses a switch as shown in the photograph above.

    Is it a good idea to light up the target for the bad guys?

    It isn’t, that is why the bad guys don’t wear illuminated badges today.
