Keystone Side Marker Light Reflector

Keystone Side Marker Light Reflectors: OEM-Grade Visibility You Can Count On

Side marker light reflectors are small components that carry significant safety responsibilities. Mounted on the front and rear corners of a vehicle, they make your car or truck visible to oncoming and overtaking traffic from the side — a critical requirement under Federal Motor Vehicle Safety Standards. When a reflector cracks, fades, or goes missing after a collision or years of road wear, replacing it promptly restores both legal compliance and roadside visibility. Browse the full Side Marker Light Reflector category to understand how wide the range of applications truly is.

Keystone Automotive Industries is one of the most trusted names in the collision replacement parts market. As a subsidiary of LKQ Corporation, Keystone Automotive Industries has built its reputation as the largest aftermarket auto parts distributor in the United States, with distribution facilities reaching most major markets in North America. That scale translates directly into depth of coverage — Keystone's side marker light reflector lineup spans 164 individual parts, covering a wide swath of domestic and import cars, trucks, and SUVs across many model years.

Two Tiers of Quality: Standard and Platinum Plus

One of Keystone's defining advantages in the lighting replacement space is its tiered product structure. Standard replacement reflectors are engineered to restore a vehicle to its original factory specification — correct lens color (amber for front-facing, red for rear-facing), proper housing geometry, and the same mounting footprint as the OEM part. For shoppers who want an extra layer of assurance, Keystone's Platinum Plus line goes further. Platinum Plus suppliers are required to meet a rigorous quality assurance program modeled on current ISO 9001 standards, similar to what OEM manufacturers demand of their own suppliers. Parts in this tier undergo third-party validation as well as internal testing before reaching the market.

SAE/DOT Compliance and Broad Vehicle Fitment

Every Keystone side marker light reflector in this lineup is designed to be SAE and DOT compliant, meaning they meet the photometric and dimensional requirements set by the Society of Automotive Engineers and the U.S. Department of Transportation. This is especially important for collision repair shops and fleet operators who need documentation-ready parts. Lens color options include amber and red configurations for both front and rear placements, with driver-side and passenger-side variants catalogued across a broad range of makes — from American pickups and full-size SUVs to compact imports and European vehicles.
