Permanent light element with incandescent bulb
Permanent light elements with BA15d sockets can accommodate incandescent bulbs (sold separately) with either 5 or 10-Watt power, for optical indication.  Common signal Lenses can be used with either LED or incandescent bulbs.  The bulb used determines
the voltage range.

Permanent light element with LED bulb
Permanent light elements with BA15d sockets can accommodate colored LED-lamp bulbs (sold separately), providing vibration proof optical indication, with long service life.  Common signal elements can be used with either LED or incandescent bulbs.  The bulb used determines the voltage range.

Blinking light element with incandescent or LED bulb
Blinking signal elements with integrated blinking circuit and a BA15d socket.  The blinking frequency is approximately 2 Hz. Blinking signal elements can be used with either LED or incandescent bulbs.  The bulb used determines the voltage range.

Blinking LED bulb
A blinking circuit is built into the LED bulb.  This bulb can be used to turn a standard permanent light element, into a blinking element.  Available for 24 VAC/DC applications only.  The blinking frequency is approximately 2 Hz.

3 Joule or 6 Joule Flashing light element
Flashing light elements are ideal for providing light indication for large bright areas, due to the high intensity light created by the integrated Xenon-flash tube.  The  flash frequency is approximately 1 Hz.  The elements are offered with either 3 or 6 Joule light intensity.  Voltage ranges include 12-48 VAC/DC, 100-120VAC and 220-240 VAC.

Audible signal element
Audible signal elements provide an extra level of indication or warning.  The buzzer module can either be installed separately or on top of a stack light. The tone can be set to continuous tone, pulse tone or two-tone via an internal switch.  Volume and frequency can be adjusted via internal potentiometers.  Voltage ranges include
12-48 VAC/DC, 100-120VAC and 220-240 VAC.

Permanent light/ buzzer
These unique elements combine the functions of a buzzer element and permanent element into one module.  Elements can be installed separately or on top of the stack light and can be used with either LED or incandescent bulbs.  The tone can be set to continuous tone, pulse tone or two-tone via an internal switch.  Volume can be adjusted via internal potentiometer.  Voltage ranges include 12-48 VAC/DC, 100-120VAC and 220-240 VAC.
