Owner report 11311568 · 2020-02-26 (February 26, 2020)
LED HEADLIGHT DO NOT GENERATE ENOUGH HEAT TO MELT ANY SNOW. A HALF AN HOUR DRIVING TIME IN STEADY SNOW RESULTS IN THE LIGHTS BEING TOTALLY COVERED BY SNOW AND COMPLETELY USELESS FOR ILLUMINATION AFTER DARK. STOPPING ON THE SIDE OF THE ROAD TO CLEAN OFF THE LIGHTS EVERY 15MINUTES IS NOT A REASONABLY SAFE ANSWER TO THIS PROBLEM. LENSES MUST BE HEATED.
