This is a brand new original Lucas SPB354 RED warning lamp for the dashboard of most British cars from about 1962 through the 1980s. This lamp fits a 1/2 inch hole and will work with just about any application. We sell these lamps in red, amber, blue and green.
We do occasionally get the earlier, multifaceted Lucas dash warning lamps, but they are becoming rare and have not been made for thirty years. Contact us if that is what you are looking for and we will try to help.
