Let's learn how to install the 2015-2017 Ford Mustang switchback LED DRL sequential turn signal lamps. The LED daytime running light assembly is the ideal LED lamp to impress other drivers and command their attention as you signal a turn or lane merge. Featuring switchback technology, the LED lamp assembly runs the daytime running lamp in xenon white by default and flashes sequentially in amber yellow when you turn on your turn signals. The lamps switch back to xenon white when you complete your turn or lane merge.

The Mustang LED DRL turn signal lights include a relay wiring harness and a pair of in-line load resistors to prevent hyper flashing. Because the turn signals are LED, they draw less power and are prone to hyper flashing.

Step by Step Instructions
1

Take out the stock turn signal light bulb from your stock turn signal harness and plug the turn signal. Twist lock the connection to keep condensation from forming inside.

Connect the resistor decoder box to the additional socket. Mount it onto a metal surface or let it hang.

Connect the red wire to your car battery (+) and the black wire to a ground or your car battery (-). Tap the yellow wire to your ACC 12V (+). The additional white wire is optional.

Tap the blue wire to your tail light (+) to enable the sequential flashing feature.

Pull out the incandescent parking light bulb from your stock parking light harness. You will not be using this harness. Plug the unused parking light harness into the opening on the backside and twist lock to keep condensation from forming inside.
