Cevap
A broken red rear lamp lens that permits bare white light to shine directly toward the rear of the vehicle.
A broken red lens that allows bare white light to emit toward the rear is a safety defect and regulatory violation. Exterior lamps must have clean, intact lenses of the correct regulatory color (red to the rear, amber to the front and forward sides). White light emitted rearward creates severe glare and misleads trailing motorists about vehicle orientation.
