This switchback LED bulb is specially designed so that it functions as a rear fog light as well as a backup light. Switching from your stock bulb to the new switchback LED reverse light/fog light bulb is not complicated and involves some pretty straightforward steps. This LED rear fog light/reverse light upgrade is compatible with 2011-up Chevy Volt and the new 2015 Ford Mustang.
Step 1: Remove the Hex and Torx screws circled in red that are located at the bottom of the vehicle’s rear.
