Amber Headlights is an album by Greg Dulli.
 In 2001, Dulli started to work on the follow-up to The Twilight Singers' debut album "Twilight as Played by The Twilight Singers".

 The song "Cigarettes" became "Follow You Down" on "Blackberry Belle".
 Three years later, Dulli decided to release the songs on his own label, Infernal Recordings.
