changed my turn signal bulbs last night and the bulbs a i changed them with "looked" the same but it was kind of dark and couldnt see the number....now this morning on my way to work...one side signal (from the inside) just stays on constant, and the other side flashes but doesnt make a sound

..
wrong/type bulb?? thats my guess....cant do anything till i get home this evening but i thought that would be the problem? just hoping its not something more........expensive...
