## What is Signal Lamp?

Read the lamp. Read the hoist. Answer the bridge.

Signal Lamp is a complete naval visual signalling course for officers, cadets and watchstanders — flashing light (Morse code), semaphore, and the international flags and pennants — built around practice, not just reading.

WHAT'S INSIDE • Flashing light — Morse timing, full alphabet and numerals, playable samples and procedure signals. • Semaphore — every arm position with clear figures and reading drills. • Flags and pennants — alphabet flags, numeral pennants, substitutes and single-flag meanings. • Four interactive drills — Morse receive with adjustable speed, Morse send by keying, semaphore recognition and flag recognition. Randomized, no repeats. • Knowledge checks — ten-question randomized tests per module with immediate feedback and an 85% standard. • OOD Bridge-Call Simulation — incoming flashing light at 8 WPM, flag hoists on an approaching warship and semaphore from a replenishment vessel. 12 seconds per signal, 85% to pass, and immediate failure for misreading hazard signals such as Bravo, Foxtrot and Charlie-Golf. Includes a rapid-fire warmup. • Progress and mastery — see which modules you have really practised.

NO ACCOUNT. NO TRACKING. No sign-up, no email, no password. Your scores stay on your device and can be erased at any time.

IMPORTANT Signal Lamp is a training aid. It is not an operational publication — always work from the International Code of Signals and your own fleet publications.
