Whelen Inner Edge RST (Rear) - PIU
Whelen's Inner Edge RST puts a full-width lightbar inside the rear window of the Ford Police Interceptor Utility - lightbar warning power with a slick-top look, protected from weather, car washes, and tampering.
Key Features & Upfitter Specs
- Hugs The Glass: The RST tray is shaped to the Ford Police Interceptor Utility's rear window, so the bar sits tight to the glass with minimal blocked view and almost no flashback into the cab.
- Pick Your Colors: Every option is named by the LED colors you actually get. Options with a dash (like "Red/Amber/White - Blue/Amber/White") list the driver side first, the passenger side second.
- One Bar, Two Jobs: Multi-color Whelen heads let the same bar run red/blue warning and switch to amber traffic-clearing patterns.
- Trusted Platform: Inner Edge is the most common interior lightbar in law enforcement - proven optics and vehicle-specific fit from Whelen Engineering.
- Fitment: 2025-2026 Ford Explorer PIU. Mounts at the upper rear/hatch window (interior).
