TOPDON ADAS Corner Reflector (LAC05-03)

The TOPDON LAC05-03 Corner Reflector is a calibration target accessory designed for use within the Topdon Phoenix ADAS calibration system. If your shop handles ACC (Adaptive Cruise Control) radar calibration or BSM (Blind Spot Monitoring) corner radar verification, this is the physical target that makes static radar calibration possible.

Corner reflectors work by returning radar signals back to the source with a known, predictable signature. During static ADAS calibration, the technician positions the corner reflector at a specified distance and angle from the vehicle's radar sensor. The calibration software uses the returned signal to verify alignment and set the sensor's zero-point. Without a proper corner reflector, you cannot perform accurate static radar calibration — a fact that matters every time a customer comes in after a front-end collision, bumper R&R, or suspension alignment that disturbs radar mounting geometry.

What It's Used For

• ACC Radar Calibration: Used as the primary static target for front-facing radar sensors that control adaptive cruise control systems.
• BSM / Corner Radar Verification: Supports static verification of blind spot monitoring radar units mounted at the vehicle's corners.
• Phoenix ADAS System Integration: Designed to work with the Topdon Phoenix Mobile and Phoenix Smart calibration frames as part of a complete ADAS calibration workflow.
• Post-Collision and Bumper R&R Work: Required any time radar sensor mounting position has been disturbed — including bumper removal, front-end repair, or sensor replacement.

Who Needs This

If you already own or are building out a Topdon Phoenix ADAS setup and you're taking on radar-equipped vehicles, the LAC05-03 is a required component. Shops doing windshield-only work may not need it immediately — camera calibration uses flat target boards, not corner reflectors. But if you're handling full ADAS calibration including ACC and BSM radar systems, you need a corner reflector in your kit.

This is also the right purchase if you're replacing a lost or damaged corner reflector from an existing Phoenix ADAS kit, or adding a second unit for shops running two calibration bays simultaneously.

What's in the Box

• LAC05-03 Corner Reflector unit — the calibration target itself
• Any included mounting hardware or storage case as shipped by Topdon (confirm current kit contents with our team before ordering if this is critical to your workflow)

Important Notes Before You Buy

• This is an accessory component, not a standalone calibration system. It requires a compatible Topdon Phoenix ADAS frame and software to function as intended.
• Exact placement distances, vehicle coverage lists, and calibration procedure details are managed within the Topdon ADAS software. Consult your Phoenix software documentation or contact us for guidance on specific vehicle applications.
• If you are unsure whether this reflector is compatible with your current Topdon kit version, call us before ordering.
