What is the advantage of the switchback function?

The switchback function allows the LED halos to operate as both a white DRL and an amber turn signal. This provides increased visibility and a custom look for your Sierra 1500.

Do I need any special tools to install these halos?

Professional installation is recommended since the headlights need to be opened to install the halos. You'll also need to use the included T-tap connectors to connect the drivers to ground, parking signal, DRL, and turn signal on each side.

What kind of warranty does Diode Dynamics offer on these LED halos?

Diode Dynamics includes a 3-year replacement warranty. This covers any defects in materials or workmanship.
