Historical information

Blackout headlight covers were commonly used during World War II and post-war military operations to reduce vehicle visibility at night and minimize detection by enemy aircraft.
They were especially used in military convoys, air raid precautions (ARP), and civilian vehicles during blackout regulations in wartime cities.
The small opening and louvered slats allowed some light for safe driving while preventing full illumination, which could have exposed vehicles to enemy attack.
These covers may have been used on military jeeps, trucks, or civilian vehicles following wartime restrictions.

Physical description

These are four round headlight blackout covers, used to restrict the amount of light emitted from vehicle headlights.
Each cover is circular, designed to fit over standard vehicle headlights, with a small open hole for limited light emission.
A horizontal slotted section with ridges or louvers allows some light to pass through while preventing full illumination.
Three of the covers appear to be painted black, while one shows significant rust and wear, suggesting it is made of metal and has been exposed to the elements over time.
The surfaces show signs of chipping, scratches, and general age-related wear.
