New Mexico Headlight & Wiper Law
New Mexico runs the half-hour night window and a 500-foot visibility trigger (NMSA 1978 66-3-802). No separate wiper statute, but rain, blowing dust, or snow heavy enough for the wipers pushes you under 500 feet, which trips the rule. Low beams in fog and dust — high beams reflect straight back and blind you. DRLs and 'AUTO' don't light your tail lamps, so flip the full switch on.

Night, low visibility, and daytime
- One-half hour after sunset to one-half hour before sunrise, and any time there isn't sufficient light to clearly see persons and vehicles 500 feet ahead (NMSA 1978 66-3-802).
- No statewide work-zone headlight mandate; obey posted 'Headlights On' signs on mountain and pass sections, where the sign is its own duty. DRLs aren't required and don't meet 66-3-802 — front-only lamps leave your rear dark. Turn headlights fully ON, low beam.
