Low Beams do not function

[blackace4]

My 2007 Yaris Hatchback has a problem. My day running lights do not come on, and low beams also do not work either. My high beams come on when I move the control arm is in forward position as well as when I pull the lever towards me. When the lights are turned in the on position the little clear bulb comes on only but not the low/high beam combo bulbs. Also the blue high beam light does not illuminate anymore on the instrument panel. Turn signals, rear lights, etc are all fine . Do I simply replace the bulbs? My daughter noticed 2 days before this happened the right side bulb was not on when the other side was during daytime running position. When she turned to low beam position it worked.
