Hazard
In yellow flashing lights equipped on road maintenance vehicles, manufacturing variations in the main gear that rotates the reflector can cause the gear to contract at low temperatures, eliminating the clearance between the main gear inner diameter and the bulb socket boss. When this occurs, the main gear and reflector become immobile, causing the flashing light to cease flashing.
