If you own a dually Super Duty and want brighter, longer-lasting side markers without cutting or splicing, these DERMOKA units are engineered as a plug-and-play upgrade for factory locations.

Will these fit my Ford F250/F350/F450/F550 dually truck?

These marker lights are made to match the original side marker mounting points for 2011–2022 Super Duty dually bed fender assemblies that already have side markers. If your truck uses factory-style marker housings, installation is straightforward.

• Compatible with 2011–2022 Ford F250/F350/F450/F550 Super Duty dually trucks
• Designed for trucks with existing side marker housings
• Sold as a set of four lights for complete replacement

How do these LED markers perform compared to OEM bulbs?

DERMOKA equips these markers with high-power LED chips that deliver significantly higher output than standard incandescent bulbs, improving side visibility and making turn/parking signals easier to see. LEDs also run cooler and maintain brightness for many more hours.

• Approximately five times brighter than typical OEM bulbs
• Rated lifespan beyond 55,000 hours for long service life
• DOT & SAE certified for road-legal use in applicable regions

How difficult is installation and what tools are required?

Installation is plug-and-play—no cutting, splicing, or complex wiring is necessary—so most installations take under 15 minutes per side for a standard swap. The lights are made to drop into the existing mounting points and use the truck's original connector, minimizing risk to the factory wiring harness.

• No modification to the truck’s wiring or housing required
• Typical install time: under 15 minutes per light for experienced DIYers
• Only basic hand tools may be needed for access or panel removal

Are these lights durable for everyday and off-road use?

The housings are injection-molded ABS with a tough smoked PC lens and environmental sealing to withstand road vibration, moisture, and dust. They are built to resist typical automotive stresses, making them suitable for regular highway driving and work-site conditions.

• Weather-sealed: waterproof, dustproof, and shock-resistant
• Durable ABS housing with impact-resistant smoked polycarbonate lens
• DOT & SAE certifications indicate compliance with many safety standards
