Phillips PR21WC1 Fog Light Bulb - Rear

OE-Style Rear Fog Light Bulb

The Phillips PR21WC1 is a 12-volt incandescent fog light bulb built to match original equipment standards for exterior lighting applications. It uses a clear glass bulb body, a BAW15s base, and a single C-6 filament to deliver consistent rear lighting performance for select vehicles.

Phillips Standard - Single Commercial Pack is the brand’s OE-focused lighting line, offering the same type of quality used in factory lighting systems. For drivers servicing a Hyundai Kona Electric rear light, Audi A6 rear lighting, or Saab 9-3 rear lamp application, the PR21WC1 provides a direct replacement option with standard-fit construction.
