Low beam out

On my 1996 Impala SS, the low beam in one of my headlights just went out. Is this something I can fix easily or should I have a shop do it? Is it just a bulb to replace or the a whole sealed beam headlight? Any advice on what to do will be welcome.

It takes a 9004 headlight. They have a little clip that hold them in from the back. Just unplug the light, remove the clip and the bulb will come out. Install the new bulb, do not touch the glass. Plug in the connector and you are done.
