Every light needs a source. For these hats, it’s a 4.5V power supply built from three AAA batteries—simple, dependable, and thoughtfully positioned.
Battery Configuration: Three standard 1.5V AAA batteries in series, providing a steady 4.5V output.
Holder: A compact, lightweight battery holder chosen for durability and ease of maintenance.
Custom Exterior Cover: Crafted from cardboard and reinforced materials, this protective cover shields the battery holder while anchoring it securely to the outside of the hat, just behind the left ear. This placement keeps the power source accessible while preserving interior comfort.
Shielding Layer: To prevent any discomfort or electrical interference, a thin aluminum insulating shield is placed inside the hat. This layer ensures safety and adds another degree of protection without compromising flexibility.
This configuration was designed for long runtimes, comfortable wear, and practical assembly. It powers the red and blue LEDs for up to seven days of continuous glow, standing as a quiet engine behind every moment of visibility and honor.
“What powers the light is often unseen—but never unimportant.”← Back to Page 1: Introduction
