Brake light issue
Hi all
I have a 04 F150 FX4 crew and I'm having an issue with my brake lights. When I depress the pedal while the truck is on the flicker. As I depress the brake pedal, they then work fine. Only happens when I start to depress the pedal.
Also this doesn't happen when the truck ignition is off.
Any ideas?
Kind of thinking it is a resistor or something under the dash
Any suggestions will be helpful
Thanks
Jack

brake pedal switch itself may be taking a dump on you...

Like techrep said maybe the brake switch is going. I have seen similar happen when an alternator or battery is not fully charged. I know that sounds crazy! My friends BMW would do that after hr bought it because the battery wasn't at a full charge. If you're driving long distances and your battery is topped I can't see that bring the case. Is it a continuous flicker? Constant, flickering at the same frequency?
