I have a 1984 Morgan 323 with Xantech interior lighting. These are two postiion fluorescent 12 volt light. Maybe the postitions are one for white and one for red? Does not seem to matter which position they are in. The ballasts are starting to wear out so I would like to either get parts or replacements. These lights are 2 1/4" x 24" and I really like them. Thanks for any help you can offer.
