Product Details

Phillips MasterDuty is the commercial-duty lighting line from Phillips, focused on durability in demanding operating conditions. The H1MDC1 uses halogen technology, a clear finish, and a glass bulb body to support consistent exterior lighting performance. Its compact 0.33-inch diameter and 2.46-inch length help it match the original bulb form factor in many fog light and headlamp positions. This part number, H1MDC1, is listed across numerous fitments such as 2018-2020 Ford Escape, 2011-2019 Volkswagen Amarok, and 2017-2019 Hyundai Creta, making it a practical choice for drivers and fleets that need a dependable replacement bulb.

This part cross-references common H1 applications for the same bulb style and base configuration.

Common Uses

• Restores fog light output when the original bulb is dim or burned out
• Replaces a failed high beam or low beam bulb in listed halogen applications

Installation Notes and Tips

Verify the bulb base, voltage, wattage, and lamp position before installation. This H1MDC1 bulb is used in multiple positions depending on the vehicle, including fog light, high beam, and low beam applications, so match the original bulb specification exactly. For best results, avoid touching the glass with bare hands and confirm proper alignment after installation. Fitment examples include 2014-2020 Ford Transit Custom, 2015-2019 Ram 700, and 2007-2013 BMW X5, with position and headlamp configuration noted in the vehicle listing.
