This panel set is for the Vanagon gauge cluster to allow the original OXS warning lamp to be used as a check engine light. It is necessary for California conversions but it is helpful for all conversions to indicate engine malfunctions and for reading blink error codes.
Available in the stock color or in white to match Small Car's white gauge faces.
For vehicles without an OXS light, another LED can be added in the blank lower left position and it will work the same way.
