Many owners of classic Jaguars find the dashboard lights dim and the instruments difficult to read at night. We've matched up the various Lucas bulbs with super-bright LED counterparts to solve the issue completely. These kits include bulbs for the instruments, panel lights, warning lights and interior lights. Because LEDs are polarity sensitive, please take note if your XK has been converted to negative ground. Finally, each kit is assembled from individual parts at the time of order, so not to worry when the kit part number shows no stock.
