There are some variations to these, but there is nearly no exception to steady amber meaning the tanker is ready and steady green meaning the fuel is flowing.  The lights can also have a different arrangement, but usually there are two bulbs of each color either in the lamp or as two separate lamps.

According to MIL-A-19736A, section 3.7.5.1 the signal lights should be automatic for these circumstances:
; Yellow light:  Turned on only when the hose is within 5 feet of the trailed position and the tanker is ready for engagement.
; Red light:  Turned on when the hydraulic pressure at the hose reel is too low for proper response action.
; Green light:  Turned on when the fuel is being transferred to the receiver. The light shall be controlled by a primary element which senses actual fuel flow.
The light can be dimmed and the yellow and red lights function for both dry and wet engagements.
