brake lights

I just put a new brake light switch on my car and now only 1 light lights up when i apply brakes. Why would the other one not light up? it turns on when you turn night lights on.

This might be a dumb question but is the bulb good? the night lights and brake light is different filaments one could be broke and the other still work.

?
was the bulk you used an 1157?

it may be a bad socket or more likely, a break in the wire from the bulb to the harness.

if it is the right side bulb, look between the right side wire and the left side socket.
