Red is a wrong choice - a color harder to detect. Automobiles
designed by engineers (not by fashion designers) use orange (amber)
rear turn signals. Orange cuts through fog, smoke, rain, etc; and is
easier to see at dawn and dusk.

Sources of motion sensors include those $1 electronic pedometers or
game handles from Wii video games.
