XK-150, Later, With Tachometer Generator, Cars Converted to Negative Ground. 8 Pieces. Sample shown in photo; actual kit may vary. Please note kits are assembled from individual components at time of order and will not show in stock. Many owners of classic Jaguars find the dashboard lights dim and the instruments difficult to read at night. WeÕve 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 positive ground XK, Early Sedan or 3.8 E-Type has been converted to negative ground. This kit will not show as being in stock as it is assembled from individual pieces when ordered.
