flicker is that a constant flicker or just once as the brake lights come?012chevy012 said:Hello silverado owners, here's another problem i just noticed, maybe somebody else has noticed too.
When I step on the brakes the headlights flicker a little when idling, just noticed the other night.
Exactly....wildchevy said:Totally normal to see headlight dimming in 06 and up trucks equipped with the fuel saving charging system, it is slow to react to extra demands like brake lights and power window usage. The alternator is controlled by a module and keeps drag on engine to a minimum in order to increase MPG. I have experienced the same thing on my 06 09 12 14 and 16 trucks from day one on each truck.
