Abstract
A microprocessor 4 detects the voltage delivered by a vehicle battery 3 in operation and energises light-emitting diodes D by enabling an on/off current to flow from the battery to the diodes with a duty-cycle which is variable in a predetermined manner in dependence on the value of the battery voltage. The duty-cycle is generally decreased as battery voltage increases, and may be lowered if a vehicle light 6 has been turned on. The microprocessor 4 controls airflow devices (P-Z) in response to sensor and controls (A-N).
