The Switchback and Amber DRL LED Boards for the 2016-2018 Chevrolet Silverado add a brilliant amber turn signal along with either an amber or white daytime running light. These boards are a direct replacement for the factory LED panels inside the headlight — no modification required. Here's the full walkthrough.

Installation Instructions
Step 1 — Remove the Reflectors
With the headlamp open and lens removed, remove the six T20 screws holding the DRL and turn signal reflectors in place. Remove the turn signal reflector and set it aside. Then remove the DRL reflector housing the factory LED boards and disconnect it from the headlamp housing.
Step 2 — Swap the LED Boards
Remove the four screws holding the factory LED boards in place and remove the factory boards. Place the new Diode Dynamics LED boards into position — all holes should align perfectly. Replace the original screws to secure the boards. Note: The third board will not be replaced.
Step 3 — Connect and Reassemble
Connect the included wiring harness to the boards (it doesn't matter which connector goes to which board). Reinstall the DRL reflector into the headlamp using the alignment holes and replace the top two original screws. Reinstall the turn signal reflector and replace the last four screws.
Step 4 — Route the Wires
Run the wiring harness outside of the headlamp, sealing any holes you create. Repeat for the other headlamp.
Wiring Instructions
Step 5 — Connect the Driver
Connect the board to the Switchback driver, then connect the driver to the pigtail. Tap the pigtail wires to the factory wiring harness per the included wiring diagram. The black wire must be grounded before any function will work.
Important: Do NOT plug the LED panel directly into the pigtail without the driver. The LED boards must be connected to the driver first to control power.
Step 6 — Mount and Reinstall
Mount the driver outside the headlight for serviceability, in a location away from the engine block to avoid excessive heat buildup. Tuck all wires. Test thoroughly and reinstall headlights onto the vehicle. The install is complete.
