There’s nothing in the manual about this light, and nobody seems to even know what it’s called, which makes it hard to explain to people what the problem is. Part of the problem is that it flashes all the time, whether the car is locked or unlocked, and when it’s being driven. That’s a problem because it’s clearly visible at night if you stand in front of the car and, at least in the UK, it’s an offence against the lighting regulations for a motor vehicle to show a red light to the front. That makes it technically illegal to drive.
