Speed Turtle Easy Flash 2.0

Best money I've ever spent on a vehicle mod. It's literally plug-n-play. Just hook it up to the obd2 plug and let it do its self setup in a few seconds. You don't actually even need the switch or wire harness to activate it. Long press a particular button on the steering wheel of my 2013 Ram 1500 and all the lights start to flash in sync. I'll be wiring it up to a pair of switches though so I can activate just the front or just the rear lights. The configuration software is super easy to use to configure what the switches do.
