Precision Digital offers three different light configurations in its line of Light / Horn devices. 

The first option is a factory ordered Light / Horn with a color of either red, green, yellow, blue, or white. 

The second option is a Light / Horn the user determines the light color (red, green, yellow, blue or white) by connecting the appropriate wire. 

The third option is a Light / Horn with red, yellow, and green layers the user can turn on independently. 

The light on the Light / Horn can be wired to flash (not available on PDA-LH5C) or stay steady on and the horn is rated at 85 dB. 

The light and horn can be controlled independently of each other via separate relays on the Precision Digital meter; and since the meter's relays can be reset in a variety of ways, there are several ways the Light / Horn can operate. 

For instance, the horn can be programmed to silence at any time via the Reset Button or F3 front panel button (on ProVu models), and light to turn off automatically when the alarm clears.
