This unit of competency specifies the outcomes required to select and install light emitting diode (LED) systems into signs. It covers identifying the appropriate LED system to achieve job requirements, laying out and installing the system into position, and connecting and circuit testing the system to ensure consistent distribution of light.

The unit supports sign manufacturers producing illuminated signs. It applies to signs illuminated using LED technology, including light boxes and fabricated letters which, depending on how the modules are positioned inside the letter, will produce either face-illuminated or halo-lit signs.

Where LED lighting is less than 240 volts, no licensing, legislative, regulatory or certification requirements apply to this unit of competency at the time of endorsement. Should lighting be above 240 volts, relevant state and territory regulatory authorities should be consulted to confirm licensing, legislative, regulatory or certification requirements that apply to this unit of competency.
