Keystone Roof Marker Light

Keystone Roof Marker Lights: OE-Quality Cab Clearance Lighting

When it comes to keeping your truck visible, legal, and road-ready, roof marker lights are far more than an accessory — they are a federally mandated safety item for trucks over 80 inches wide. These small but critical lights run across the roofline, signaling your vehicle's width and height to oncoming traffic and reducing the risk of side-swipe and underpass collisions, particularly at night or in low-visibility conditions. Choosing the right replacement matters, and Keystone Automotive is one of the most trusted names in the aftermarket parts industry for exactly this kind of job.

Keystone Automotive Industries, a subsidiary of LKQ Corporation, is recognized as the United States' largest aftermarket auto parts supplier, and its reputation is built on delivering high-quality, low-cost alternatives to new OEM replacement parts. As an ISO 9001-compliant distributor, Keystone holds itself to rigorous quality standards across its entire lighting catalog — including cab and roof marker lights designed to meet or exceed original equipment specifications.

Keystone's lighting lineup covers a broad range of truck makes and models, making it a practical go-to for both professional repair shops and DIY enthusiasts. Their roof marker lights are engineered to be direct-fit replacements, meaning installation is straightforward without modification — a crucial factor when you need to get a commercial truck back on the road quickly. With SAE/DOT-compliant designs, buyers can have confidence that Keystone's marker lights satisfy Federal Motor Vehicle Safety Standards (FMVSS) requirements.

• SAE/DOT compliance for legal road use on vehicles where marker lights are federally required
• Compatibility with popular truck platforms, including domestic and import pickups and heavy-duty commercial vehicles
• Both incandescent and LED-compatible options to suit OEM-spec replacements or modern efficiency upgrades
