Marker Lights LED Top Roof Lamps Fit for International Prostar

In this review of the Marker Lights LED Top Roof Lamps, the bottom line is simple: these are a no-nonsense, direct-replacement set of cab roof marker lights for International Prostar, Durastar, and Workstar trucks from 2008 to 2018. The reviewer found the plug-and-play fit and solid build to be the single biggest reason to buy, as they replace worn or damaged OEM 3524553C94 lights quickly and restore visibility without electrical modification. Owners who want a durable, waterproof LED solution that installs fast will appreciate this practical upgrade.

Key Features

• Direct fit: Designed to match the OEM 3524553C94 footprint so installation requires no wiring changes and saves time.
• LED illumination: Provides brighter, more consistent marker light output than aging incandescent bulbs for improved visibility.
• Durable construction: Waterproof and treated against UV to resist fading and handle roof exposure over time.
• Plug & play installation: Easy to install right out of the box, reducing downtime for fleet vehicles or single-truck owners.
• Aftermarket quality: Built from high quality parts meant to serve as a reliable, direct aftermarket replacement.
• Warranty support: Includes a one year warranty and seller support for questions or issues.

Who It's For

The Marker Lights LED Top Roof Lamps are best for truck owners and fleet managers who operate International Prostar, Durastar, or Workstar models from 2008 through 2018 and need a straightforward replacement for worn or broken roof marker lights. They suit technicians or DIYers who prefer a plug-and-play solution that restores proper marker illumination without chasing connectors or adapters.

These lights are less appropriate for very old or non-International models, or for owners who need custom lighting shapes or integrated electronics beyond standard marker functions. If a vehicle requires a different size or non-standard wiring, another assembly would be a better choice.
