1984-1989 Corvette Photocell Dimmer Restoration Kit
Cluster too bright at night, or too dim during the day?
The Photocell kit contains a photocell, dimmer transistor and capacitor, and correct solder
The digital cluster contains a photocell sensor which allows the cluster to attain full brightness during daylight, and to dim around sunset. This is still the case with the headlights on - the information should appear brighter in the daylight than it does at night.
Our photocell kit contains a new, factory-fresh photocell which is an electrical and physical size match for the factory part. No additional resistors or modifications needed! The kit also includes a replacement dimmer transistor and electrolytic cap, and a supply of the correct solder used in the digital cluster.
Example of Cluster with defective photocell
Signs your cluster may need this repair
The digital cluster is working properly, except that the information is very dim (or too bright).
The four bulbs that illuminate the cluster are very dim, not completely dark.
The cluster works at full brightness when the key is turned on, but goes very dim after a few seconds.
The cluster is dim with the headlights off, but works normally when the headlights are on.
This is a great time to replace the factory bulbs with our Xenon bulb kit! - Click Here
Replacement Dimmer Transistor
33uF Dimmer Capacitor
60/40 Tin/Lead rosin core solder (don't use acid core or lead-free solder on the cluster!)
