Signal Light for Android - Download Free [Latest Version + MOD] 2025

Whats new in Signal Light v1.0.4

3 things about Signal Light

1. This app is based on the old mechanical “signal lamp” which is a manually-controled shuttered spotlight used on warships to communicate securely while maintaining radio silence.
2. Use it to communicate with distant friends using Morse code, tap out a beat for a human-powered strobe light, or get the attention of rescuers.
3. Put a paper towel tube on the flash to make a tight spotlight and you’ve got a line-of-sight communication tool that only you and your partner can see.
