Description:
Where the V1 keeps the factory flashing behaviour, this version adds the sweep — and on a car as wide as the Mark X, a sequential indicator running the full lens width has real presence. Fiber light guides give the continuous glow that makes the original bulb clusters look dated, and a built-in bulb-failure resistor keeps the dashboard quiet after the swap.
Features:
• Sequential Turn Signal: Full-width sweeping indicator.
• Fiber LED Illumination: Continuous light guides instead of visible bulb hotspots.
• Warning-Light Ready: Built-in bulb-failure resistor plus supplied hyperflash resistors.
• Cold-Climate Compatible: Fits rear-fog-equipped cars without modification.
• 90-Day LED Warranty: Coupler-on connection with a built-in reflector.
For Mark X owners who want the modern sweep as well as the modern glow, across every 120-series grade.
