Or like at a railway crossing. The flashing lights indicate danger, and the barriers drop. According to GP, the lights should flash when the barrier is not dropped, because now it's unsafe, FFS.
Reprogram your brain for "Red means danger, green means safe" and you'll do a lot better.
Red at a traffic light means there's a danger so you stop. Green means it's safe to proceed.
Red on a gun safety switch means danger because it's live.
The red wire is live and dangerous. The green wire is earth and safe. (at least true in Europe).
Red lights on top of towers isn't trying to tell planes and helicopters to stop, its telling planes to exercise caution around the tower.
