2009 Prius - Driver side headlight

Hello all,
I bought a 2009 prius with very low mileage. Happy about it so far. I just realized that the driver's side headlight is not coming up every time I switch it on. The passenger's side is fine. I also here a buzzing sound - for a lack of a better term - if it does not. I suspect there is a lose connection somewhere. Since it's out of warranty, I like to get it checked and repaied at the cheapest possible way.
I'm in Orange County, CA. Any recommendations are appreciated.

Regards,
