It has 3 wires. Connect one to ground, one to the parking lights and one to the turn signals. It flashes when you use the turn signals. It stays on all the time when you use the headlights or parking lights. But if you have your parking lights on and use your turn signals, it doesn't respond. It just sits there, lit like a parking light but without blinking or changing brightness. The case is also fairly hard plastic and the fit in the 3/4" hole is VERY tight. I pushed it in with a rubber mallet and almost destroyed it, prying it out with a screwdriver to pry it back out.
