Ahh , crazy brake lights, this is weird HELP
Ok, my top mount brake lights are not working, so i thought maybe it was the bulbs themselves, so i went to autozone and brought two new ones. well i pulled the cover off and the bulbs looked fine, but i recplaced them anyways. NOPE still didn't work. So i get my digital multimeter and test the voltage. 11.5 volts when brake pedal pressed. 13 volts when car is on BUT,, this is with the bulbs OUT. i put the bulbs back in, tested the voltage, probbing the SAME place, ZERO volts. 
it makes no since, so i take out just one bulb, and leave one in. still ZERO volts, i don't get it. when the lights are in, the voltage goes down to zero, take them out, it goes up to 12.
wut is causing this? its so confusing
