Upgrading to LED is one of the most effective ways to modernize your Jaguar's appearance and safety profile. Since your XJ8 uses a single H7 LED bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Don't forget the 9006 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
