What colors are flashlight cones used when directing traffic?

• A. Red And Clear
• B. Red And White
• C. Blue And Clear
• D. Green And Clear

Answer: (A)

Directing traffic with a flashlight relies on using a signaling color that stands out and a clear illumination option that keeps your visibility intact. The red portion of the cone is used because red light preserves your night vision and is immediately understood as a warning or stop signal by drivers. The clear portion lets you illuminate the area normally without distorting color perception, so you can see hand signals and the roadway clearly.

This combination—red for signaling and clear for illumination—gives you the best of both worlds: a noticeable cue for drivers to stop or proceed with caution, plus bright, reliable light to read the scene and your signaling gestures. Other color options aren’t standard for these cones because they don’t convey the same clear signaling or can interfere with night vision and visibility.
