ROULER ProlinePI Magnetic Tow Light Kit 12V LED — 20ft Harness, DOT/SAE Compliant

ROULER ProlinePI is a DOT/SAE-compliant 12V magnetic tow light kit with super-bright LEDs and a 20-foot harness designed for secure, visible towing of trailers, boats, RVs, dollies and trucks.

This tow light kit combines high-visibility LED bulbs, a scratch-resistant magnetic base and a 20-foot wire harness with a standard 4-pin connector so you can attach lighting quickly and maintain full signal functionality while towing. Built to meet DOT/SAE standards, the kit gives a reliable temporary lighting solution for vehicles that lack permanent trailer wiring or for emergency/rescue towing situations. The magnets and base design are engineered to hold on steel surfaces during transit, while the bright LEDs offer long life and clear signaling.

How strong is the magnetic mount and will it stay attached while towing?

The magnetic base is designed for strong adhesion to steel vehicle surfaces and features a scratch-resistant housing to protect paint. Proper placement on clean, flat metal greatly increases holding power; avoid mounting on plastic or heavily corroded areas. Always check adhesion before driving and periodically during long trips.

• High-strength magnetic base for firm attachment to metal surfaces
• Scratch-resistant finish to minimize surface damage
• Recommended mounting on clean, flat steel panels for best hold
• Periodic checks advised during extended towing
