I need a flasher module or other device that acts as a flasher module to control our lights. Do you have a product that can perform this action? We would like to control it with a PWM signal. The LED would ideally run on 8.4 V and 750 mA. The LED would need to turn on and completely off within a set time period. Less than 1 second.
I don’t see a flasher module anywhere on sparkfun’s site. 
Any device that can that operates on a pwm signal that can act as a switch?
