10-40v 2 Output Flasher Unit, with 5amp max on each output
With a choice of 15 flash patterns, from simple flashing, alternating, intermittent, hazard and 'emergency service' options.
Supplied with an extra 'momentary switch', you can decide to solder this to the 'selector' wire to make changing the program simple: This is not required for the flashing unit to work.
