Lincoln Mark LT Headlight Bulb Size

Additional Notes

• The 9008 bulb is the sole bulb type listed across all headlight positions for the Lincoln Mark LT, covering both high beam and low beam functions for the 2006-2008 model years.
• The 9008 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 65W for high beam output and one rated at 55W for low beam output.
• Because the 9008 handles both high and low beam functions within one unit, the Lincoln Mark LT uses a single bulb per headlight housing rather than separate bulbs for each function.
• The 9008 operates on a 12V electrical system, which is standard for passenger vehicle applications in North America.
• The 9008 carries an ANSI designation, indicating it conforms to standardized performance and dimensional specifications recognized in both the United States and Canada.
• The bulb uses a P26t base, which is a specific bayonet-style connector type. Bulbs with differing base types are not physically compatible with the Mark LT's headlight sockets, regardless of voltage or wattage ratings.
• The 9008 designation is interchangeable with the H13 designation, as both refer to the same bulb specification under different naming conventions used by various manufacturers.
