It is compatible with all 2002-2005 Ford Thunderbirds, however, 2002-2004 Thunderbirds will require new sockets http://www.thunderbirdspecialties.com/shop/tail-light-socket-replacements-2002-2004-thunderbird/ (sold separately) due to a change in the configuration of the sockets which hold the tail light bulbs. (the 2005 Thunderbird has the correct updated sockets and do not require replacement sockets) Price is for one tail light assembly only. Please specify Driver’s (left) or Passenger’s (right) side tail light.
