LED Cab Roof Marker Lights Compatible with F250-F550 Super Duty

In this review the LED cab roof marker lights are assessed for truck owners who need brighter, weatherproof clearance lights for Super Duty models. These five-piece marker lights are a direct replacement for OEM part HC3Z-15442-E and promise significantly higher brightness and IP67 waterproofing. The bottom line: for drivers who want improved nighttime visibility and a DOT/SAE approved upgrade that is plug-and-play, these lights deliver notable improvement in light output and durability while fitting most 2017-2022 F250 to F550 trucks.

Key Features

• Direct fitment: Designed to replace OEM part HC3Z-15442-E on F250, F350, F450 and F550 Super Duty trucks from 2017 to 2022 for a straightforward swap.
• High brightness: Built-in five rows of high-power SMD LED beads provide roughly 5-10 times the brightness of stock lights, improving visibility at night and in bad weather.
• Weather resistant construction: ABS housing with a high-density foam filled back and IP67 rating helps the lights resist rain, snow and fog for reliable performance.
• Plug-and-play installation: Direct replacement wiring and shape mean the lights install without modification, and factory hardware is recommended for the best fit.
• DOT/SAE approved: Legal for on-road use and supplied as a set of five cab marker lights to restore the truck's top clearance illumination.

Who It's For

The lights are best for Super Duty owners with 2017-2022 F250 through F550 trucks who want a brighter, OEM-style upgrade without cutting or splicing wires. Fleet vehicles and personal pickups that run in poor weather will benefit from the improved night and rain visibility offered by the high-power SMD LEDs.

Those who should look elsewhere include owners of older or newer model years outside the listed fitment and drivers who require a custom mounting or a different lens color, since this set is specifically a clear lens with white light and intended as a direct replacement.
