When viewed from the side you cannot see whether the turn signals have been activated or not. On the 1999 Neon the side marker lights flashed in sequence with the front turn signals. I asked the question at the dealer on whether that was how they were supposed to work and the answer was yes. I'm not sure whether that's a safety defect or just poor attention to detail but I thought it should be brought up.
