If both rear turn signals bulbs light up then I would check the "Tail" fuse its a blue 15A fuse under the driver side dash. If this fuse is not burnt then the next two parts to check is the relay. The relay in under the driver side dash above the fuse box. Then the headlight switch itself (I wouldn't suspect this switch if the front park or amber light turn on).
The only way to isolate this is to use a DC volt meter to see if power is getting through to the relay and switch assuming the light bulbs are good.
There is a chance their is a broken wire somewhere so I would have a mechanic search for this because it could be any any where from fuse box to the lights bulbs. Another likely spot is were the wire go to the lights in the middle on the trunk where the wire bend.
