Restore proper wiring and bulb function to the driver's-side rear lamp with the Standard Ignition Tail Light Circuit Board CBT111. This LEFT-side circuit board drops in as a direct-fit replacement for the 1999-2005 Pontiac Grand Am — see the Buyer's Guide tab for engine-level fitment. The circuit board carries the sockets and printed wiring that route power to the tail, brake, and turn-signal bulbs; when corrosion, heat, or a cracked trace interrupts that path, replacing the board is what brings the affected lighting circuits back online.

  • Direct-fit replacement: designed to install out of the box for a straightforward swap.
  • Tested to OE specifications: extensively tested to help ensure consistent performance and long service life.
  • Restores tail light function: once installed, the board is intended to restore proper tail light operation on the listed applications.
  • Meets or exceeds OE performance: built to give the technician the quality needed to get the job done right the first time.

If a failed left tail light circuit board is the cause of dim, dead, or intermittent rear lighting, this CBT111 replaces it. Confirm your vehicle against the Buyer's Guide before ordering.
