AND A ride height laser puts out a beam of red light, just like a laser pointer. A team typically has 4 of these on the car, one at each corner. It is impossible to see these when the car is at speed on the track. More likely, what is being seen is a slip angle sensor. This makes a bright light under the car, as if a flashlight is being ponted down from the car. There are usually 2 of these (but sometimes only one) per vehicle. These sensors tell the team engineer how much the car is in yaw, or how much the front end is sliding in relation to the rear end.(2-2-2004)
