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.
