1984-1989 Cluster Bulb Replacement

Warning! The factory bulbs can damage your cluster!


The factory Halogen bulbs damage clusters. The heat they generate melts the light diffuser panels, damages the circuit boards, and even melts the solder off the boards! To keep your cluster running smoothly, you should seriously consider replacing all the illumination bulbs in the cluster with cool running Xenon bulbs. It's money well-spent.
