This HUD is a fall back in case our automatic aiming fell through. The red lights (on right and left side) indicate that the driver needs to turn left or right. The green light indicates a clear shot and the yellow light tells the driver that the camera can't get a lock on the main light. I really like this guy since the lights do absolutely nothing to distract the driver while being perfectly visible. The coolest thing is that the LEDs are hooked up to cat5e it's super easy to connect and disconnect. Has a bit of a Borg look to it doesn't it. Resistance is futile!
