The microprocessor controlled REDARC AHLF200 is suitable for FIRE and other emergency vehicles. It has two outputs, each rated at 200W, to provide alternating LEFT-RIGHT headlight flashing for 12V or 24V negative earth vehicles. When the AHLF200 is on and the PARK light switch is off, the headlights flash alternately. When the PARK light switch is on, the AHLF200 is disabled (the PARK lights over-ride the AHLF200). This allows both headlights to operate normally, regardless of the position of the "ON" switch.

The AHLF200 is rated at 200W per side and may be used to flash either HIGH or LOW beams.

The flash rate is 90 flashes per minute.

The microprocessor controlled REDARC BUSF200 has five outputs for school bus hazard lights on 12V or 24V negative earth vehicles. The alternating outputs and strobe output draw their current from the main supply input, with a small current drawn by the "ON" switch. The alternating headlight outputs, the strobe output and the high beam disable operate only while the door is open. The alternating amber flashing lights ("WIG-WAG") outputs operate while the door is open and for 20 seconds after it is closed.

The two "DOOR OPEN" inputs allow for either a positive or ground signal to trigger the BUSF200, depending on vehicle door switch wiring.
