2015 Fusion Energi Headlight DRL Function Question

Recommended Posts

Guest utsteve90

Greetings All - I have a question for those experienced in Fusion Energi headlight electrical theory. The halogen low beam headlamp also serves (in a dimmed state) as the user configurable (new for 2015) DRL - does the DRL circuit operate by pulse-width modulation (PWM) or simply a constant, but reduced current to the headlamp bulb socket? Thanks for any insight.

Good day to you I have a 2011 f150 that i found out after the fact that a tech could go into the computer and enable the DRL function for my headlights.  With saying that they go to half brightness when I place the truck in drive.   Then as light conditions change goes to full brightness as needed by the sensor.  So my best answer for you would be a reduced current condition to the headlight.

Hope that helps

Bob
