Drivers side brake light problem

[new97v6]

I replaced the bulb with a new one since old one didnt work. i guess thatw asnt the problem though because when i step on the brake the parking light part of the bulb lights and not the brighter stop light part. anyone have this happen to them and know of a fix before i order a new socket? bulb type i put in is 2057. and it is on a 1997.
