📡Radar Detector

Radar detectors pick up the X, K, and Ka radar bands (and sometimes laser) that police use to clock speed, giving you a few seconds of warning before you're in range. Modern detectors filter out the constant false alerts from automatic-braking systems on other cars, which is the only reason a detector is still useful in 2026 — without good filtering, it cries wolf every mile. Hardwire it to a fuse tap and tuck the wire behind the headliner for a clean install. Note: detectors are illegal in Virginia, Washington D.C., and on any commercial vehicle over 10,000 lbs federally — and laser jammers are illegal in most states. Detection is legal almost everywhere; jamming is not.
