T25 Syncro Diff Lock Optic Conductor Panel

Replacement light guide for the differential lock control panel fitted to Volkswagen T25/T3 Syncro models.

This optic conductor, also known as a light guide, is fitted within the differential lock control panel assembly on Volkswagen T25/T3 Syncro models. Its purpose is to transfer light from the dashboard illumination source to the differential lock symbols and indicators, ensuring the control panel remains visible in low-light and night-time driving conditions.

The Syncro differential lock system features a dedicated dashboard control panel containing the controls and indicators for the front and rear locking differentials. This light guide channels and distributes illumination evenly across the panel, helping the driver identify the controls and monitor differential lock operation.

Over time, original light guides can become damaged, discoloured, cracked or lost during dashboard repairs and restorations. A damaged optic conductor can result in poor illumination or uneven lighting of the differential lock panel. Replacing this component restores the original lighting performance and factory appearance of the Syncro control assembly.

This part is an important finishing detail for anyone restoring the differential lock control system or rebuilding a Syncro dashboard to original specification.
