Interior Dome Light Bulb for Select Ford, Lincoln, and Chrysler Vehicles

Phillips 916LLB2 is a dome light bulb built for interior lighting service in select Ford, Lincoln, Chrysler, Dodge, Plymouth, Buick, Mercury, and INFINITI applications. It uses a clear bulb color, push-type base, and W2,1x9,5d bulb base type for direct replacement in supported dome light positions.

Key Features

  • Phillips LongerLife product line focused on value-oriented replacement lighting
  • Clear bulb color for standard interior illumination
  • Push-type design with 2 contacts for supported dome light sockets
  • 7.29 watt rating at 13.5 volts
  • Single-filament construction for interior dome light use
  • Part number 916LLB2 for accurate ordering and catalog matching

Product Details

The Phillips LongerLife - Twin Blister Pack line is positioned for drivers who want dependable replacement lighting without overcomplicating the repair. This dome light bulb is specified for interior lighting applications and is listed across a wide range of vehicles, including the Ford Taurus, Ford Explorer, Lincoln Navigator, Chrysler LeBaron, and Dodge Neon. The 916LLB2 designation helps confirm the correct bulb style when replacing a worn or failed dome light in supported upper, rear, front, inner, or liftgate positions.

Compatible With select 1983-2012 vehicles, this bulb is used in interior dome light locations where the original socket calls for the same base and electrical specification. The Phillips 916LLB2 is also a practical match for owners searching for a dome light bulb for Ford Taurus rear interior lighting, Lincoln Navigator upper dome light service, or Chrysler LeBaron rear lamp replacement.

What This Bulb Helps Address

  • Dim or failed dome light output
  • Interior lighting that no longer matches the original bulb specification
  • Intermittent illumination caused by an aging bulb filament
  • Replacement needs for rear, upper, front, inner, or liftgate interior lamp positions
  • Catalog lookup for a direct replacement using part number 916LLB2

Installation Notes and Tips

Verify the original bulb base, contact layout, and wattage before installation. Match the socket style to the W2,1x9,5d base and confirm the vehicle position listed in the fitment data, since this bulb is used in specific interior lamp locations rather than across every dome light application. For best results, handle the bulb carefully during installation and avoid forcing it into the socket.
