Why do my LED headlights flicker?
Firstly, this is normal! If you've purchased a set of Sight LED Headlight for your JK, you may notice a 'flickering' when they're on at night. The flickering is caused by the sensitive CAN bus system that runs your JK. Essentially, your JK's having trouble adapting to your new LED headlights, as they draw less current than the typical old halogen.
There are 2 ways to correct this known issue:
1. JScan App
Using the JScan App is the best way to rectify your flickering headlights. The app allows you to change the settings in the vehicle's computer to natively accept and run the Sight LED headlights.
