JScan Configuration for the Sight LED Headlights - JK Wrangler

 Jeep Wrangler JK LED Headlight Conversion - JScan App

In this article, we run through how to use the JScan App to configure your JK Wrangler for the Teralume Sight LED Headlight conversion.

What's JScan?

Without going into too much detail, JScan is an application for either iOS or Andriod that allows you to deep-dive your Jeep's ECU and BCM to fine-tune a range of different settings.

Although you can have a field day in the JScan App, learning all about cool things you can change and setup, we're going to be focusing on the headlight settings for this article.

 

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.
