928 641 923 00L - Printed Circuit foil 78 - Aftermarket

The original circuit Foil at the rear of the instrument cluster used on all 1978 cars is no longer available. With age they also delaminate causing spurious issues with warning lights and instrumentation. Fits ALL 1978 cars USA/CAN/ROW
Bryan Lutz designed a replacement that incorporates modern technology and components. 
The replacement uses circuit boards as the base and updates both the warning and illumination bulbs to LED.
Very easy to make the conversion and the Instructions are clear and well detailed.
A similar circuit board is also available for 82 to 84 cars as that circuit foil is also no longer available.
