Its rotary knob with push-button and ten tri-color LEDs lets you monitor and adjust braking power quickly, while the main module mounts out of sight behind the dash. Designed for modern tow vehicles, the Spectrum pairs vehicle-specific plug harnesses, automated leveling, and simple calibration to make installation fast and reliable.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Spectrum deliver more controlled braking?\u003c\/h3\u003e\n\n\u003cp\u003eInstead of a timed or user-guess method, the Spectrum uses a triple-axis accelerometer to sense the exact motion of the tow vehicle and trailer. That motion data translates into proportional brake application so the trailer brakes match vehicle deceleration for more consistent stops across varying loads and road slopes.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eTriple-axis accelerometer continuously measures longitudinal, lateral, and vertical motion\u003c\/li\u003e\n  \u003cli\u003eProportional output applies brake power scaled to actual deceleration\u003c\/li\u003e\n  \u003cli\u003eCompensates for uphill and downhill stops for steadier braking\u003c\/li\u003e\n  \u003cli\u003eReduces trailer surge and uneven brake wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the dash-mounted knob do and how easy is it to use?\u003c\/h3\u003e\n\n\u003cp\u003eThe user interface is a compact rotary knob with an integrated push-button and ten tri-color LEDs for visual feedback.
