Alternate flashing halogen lamps with an adjustable flash rate between 1 to 4 seconds.
Kit includes PCB, two halogen lamps with bases and all electronic components.
Note: Do Not Use An Electronic Transformer. This circuit can be powered from either a 12V car battery or from a conventional 12VAC halogen lamp transformer (eg, Jaycar MP-3044). Electronic (ie, switchmode) transformers are NOT suitable for use with this project, as their high switching frequency will cause the bridge rectifier and electrolytic capacitors to overheat.
