My brake lights would not come on
do you have 12 volts into one side of the brake switch????? follow up
One thing that I could think of is the Bulb housing could be bad or has corrosion inside that it is not allowing the bulb to make a complete connection. This part might have to be replaced. The other item you said you replaced is the Brake light Switch. Is the contact plug inserted correctly> and make sure that when you depress the brake pedal that it is hitting the brake switch toddle on the switch.
Yes, need to know if there is 12V coming out from the brake light switch. But usually the problem is in the back, either at the wire connector or at the bulb socket. A test light is handy for checking to see where the power stops. Check ground wires in the back also.
I don't have 12v coming in to the pedal switch, as you probably know there is 6 wires going in to the brake pedal switch and none have 12v.
