Upgrading to Large Touchscreen in Dodge Ram 1500 morsunled.webflow.io

One of the most overlooked aspects of upgrading to an aftermarket touchscreen is its interaction with your Ram's headlight system. A large, bright screen can be a significant distraction or annoyance at night if it does not automatically dim when you turn on your headlights. Factory stereos utilize a dedicated illumination wire (typically orange or orange-white) that tells the radio when the 2018 Dodge Ram 1500 headlights are active, triggering the screen to switch to a dimmer "night mode" with reduced brightness and often a darker color scheme. Aftermarket head units rely on this same signal to function correctly.
