WHDZ LED Double Panel Line Board — 5V USB Paintless Dent Repair Lamp, Dual-Color Reflective Faces & Suction Mount

This compact light board pairs two contrasting reflective faces with built-in LEDs and an adjustable holder so technicians can clearly see surface warps, even in low light. It uses patterned reflection to make dents visible: distorted lines pinpoint problem areas so you can accurately push or pull metal back into shape without repainting. The unit runs off 5V USB power and mounts with powerful suction cups for hands-free work on flat vehicle panels and glass.

How does the WHDZ line board show dents more clearly?

The board projects crisp linear reflections across a vehicle panel; any deformation bends those lines and makes the defect instantly obvious. You align the reflected pattern so the distortion is centered, then use your PDR tools while watching the lines return to straight. This visual feedback helps you control pressure and movement to avoid overworking the metal.

• Double-sided design: white/black and yellow/black face options for contrast on different paint colors
• Built-in LEDs illuminate lines in dim or indoor environments
• Thin printed lines increase sensitivity to small surface deviations
• Adjustable holder allows changing viewing angle and distance for precision

What power and mounting options does the lamp provide?

The board operates on low-voltage USB power (5V) for compatibility with common chargers, power banks, and vehicle USB ports, keeping setup simple at the shop or roadside. Two strong suction cups secure the unit to flat metal, glass, or plastic surfaces for a stable working position without clamps or adhesive. Positioning at roughly a 45° angle is recommended to maximize reflected line definition.

• 5V USB input: works with power banks or vehicle USB ports
• Two 2.5-inch suction cups for firm mounting on smooth surfaces
• Adjustable holder for angle and height control
• Compact footprint (approx. 8.3" x 13") for maneuverability in tight areas

Which face should I use for different paint colors and lighting?

The board’s two-sided faces give you visual flexibility: the white/black side offers strong contrast on darker finishes, while the yellow/black side improves visibility on lighter or high-gloss surfaces. Choose the face that produces the sharpest reflected lines for the panel color and ambient light where you’re working; switching faces can reveal subtle distortions that one color alone might miss.

• White/black face: higher contrast on dark paints
• Yellow/black face: improved clarity on light or reflective finishes
• Built-in LEDs cut through dim conditions and nighttime jobs
• Flip or reposition quickly to compare reflections

How do I use the board safely and effectively with PDR tools?

Mount the board securely on a smooth section near the dent, set the board at about 45° to the panel, and align the printed lines so they cross the affected area. Work slowly with your dent tools and watch the reflection; when lines become straight and parallel again, the panel is restored. Keep movements controlled and avoid excessive force to prevent creating new distortions.

• Attach suction cups to a clean, flat surface for stability
• Position at 45° and choose the face with best contrast
• Adjust holder height and angle for an unobstructed view
• Monitor reflections continuously while making small adjustments

Who is this for: The WHDZ LED Double Panel Line Board is built for paintless dent repair technicians, mobile detailers, body shops, and DIY enthusiasts who want a portable, reliable visual aid for assessing and correcting surface dents. It’s particularly useful for night work, roadside repairs, and situations where quick, non-destructive diagnostics are needed without paint removal.
