Corvettes from 1978 to 1989 have a courtesy or dome light timer which leaves the interior lights on for a short period of time after the last door is closed. On a late C3, the courtesy light timer is located below the right A-pillar and behind the dashboard trim. On an early C4 Corvette, the dome light timer is behind the right side of the instrument panel.

Zip Corvette sells replacement circuit boards for both the 1978-1982 C3 and 1984-1989 C4 timers. With both C3 and C4 Corvettes, once you get the timer module removed and disconnected, you simply open the timer, remove the existing burned-out circuit board and replace it with Zip’s new circuit board.

If you are buying a board, there is also a choice of two light shut-off strategies. Zip Corvette’s standard dome light timer board has the stock delay on light shut-off after the last door is closed. Zip, also, has a no-delay circuit board which eliminates the delay, ie: when the last door closes, the courtesy lights go out immediately.

All of Zip’s Corvette Dome Light Timer Circuit Boards are made in USA. They are burned-in and tested before shipping. Each timer uses the existing stock connections so no wiring work is required for installation.

C4 Corvette Circuit Board Update – 2/7/11

1984-1989 C4 Corvettes could have three different interior lamp delay modules installed in them.  The modules can be quickly identified by the part number on the outside of the housing.
