All have a common choice of lenses in 6 colours: amber, red, green, blue, clear & white.

Housings/bezels for 19, 22.5, 26.5 & 30.5mm diameter panel holes in chromed brass or plastic.

All (except neon units) can accept filament, LED4 or LED7 cluster LED bulbs.

All bodies screw to the housing. click here for housing range.

Bodies accommodate MES (E10) bulb caps as standard with the alt option of MBC (BA9s) bulb caps.


TMU -Transformer indicator. 

A low voltage bulb is supplied from the ac control voltage via a transformer. When a filament bulb is used its life can be increased by up to 4 times.

Standard supply voltages (ac only): 24V, 100/120V, 220/240V & 400/440V

Standard bulb voltage: filament - 6V 1.8W or LED cluster 4.5Vac Supply Frequency 50/60Hz

MTMU - Multi-test indicator for ac supply.

A transformer lamp as above with the addition of a circuit to enable group testing of lamps from a single pushbutton switch with the panel fully operating.

Standard supply voltages (ac only): 24V, 100/120V, 220/240V

Standard bulb voltage: 6V, LED cluster 4.5Vac

DTMU  - Multi-test indicator for dc supplies.

A direct voltage lamp with a circuit to enable off-line testing of a group of lamps from a single pushbutton switch. DC supply voltages: 6,12, 24, 28, 50, 60V Bulb voltages: as supply.

LMU - Direct Voltage indicator.

A simple direct voltage lamp holder suitable for filament lamps, LEDs or neons.

Supplies: AC or DC
