Wire wound resistors silicon coated / metal film resistor silicon coated are used with the 22.5mm size, while potted ceramic wire wound type resistors are used with the 30.5mm size to make these indicating lamps adaptable to the various standard control voltage range in AC & DC systems. Coloured lenses are used with the filament types, to emit Red, Green, Blue, Amber and White lights.

Good quality coloured LED Clusters are used in the LED type, emitting Yellow, Red and Green light through transparent lenses are offered.
