2005 silveado brake light keeps going out

my brake lights keep burning out. i checked the fuse,harness, and wires and all seems good. if i change the bulb i might get a day, or a week out of it. Its mostly the right side, but the left has gone out a few times also. the cab brake light has never gone out. is this a common problem? should i greese the bulb connection?
thanks

Not sure if this will help, but might be worth a try: Check your ground connections to the light assembly and sockets. Make sure sockets are free of corrosion and dirt. All I can think of. Good luck!

I had a 90-something Achieva and one of my brake lights was out - when I pulled the bulb, I saw the socket was full of something like grease. Once I cleaned all that crap out, the bulb worked fine.

check to see if their is a technical service bulletin from gm about this, you can find it online for free. with a multimeter check for low resistance to chasis ground at the socket. also have a helper step on and off the brakes while you check voltage at the bulb, while checking voltage have someone shake the truck look for voltage spikes. make sure the bulb is seated clean and secure. if its a bit loose apply a tiny bit of clear di-electric grease to a cleaned socket, after that its schematic time.
