so my brake lamp light is on... and i checked my brake lights... and indeed they are. when i press down the brake pedal, the 3rd brake light doesn't light up, nor does my driverside tailight get brighter, just my passenger side. I looked at the noob guide, and found the bulb sizes... I THINK.

Tail light |1157 ----Is this the same for the brake light in the tails?
High mount stop light | 7440 ----- Is this for the 3rd brake light?

thanks guys!

 

brake/tail=same shit (1157),and yes high mount stop light is the 3rd brake light......
