Q&A

After a crash in formula 1, why do the rev lights that tell the driver when to change gears always flash in an unusual sequence? | Q&A

The steering of a F1 car can cost up to $50,000 alone! These have made the cockpits more and more clutter free to the extent that dashboards no more exist on Formula One cars.

 

All the data is displayed here and many settings of the car can be changed by the driver using various dials, switches and buttons. Imagine remembering all the positions and settings of each button subconsciously so that you can use them even in the middle of a corner while hot-lapping!

The shift lights are the Formula One driver’s best friend. They tell the driver precisely when to shift. The order in which they light up is all to the driver’s preference. They don’t have to be of any particular color, as long as all the colors used are contrasting.

Above all, they give vital information about the status of the pit-limiter and tell if there’s a yellow flag or not.

When the pit-limiter is ON, the white lights light up alternatively on either side of the steering.

In case of a yellow flag, they flash alternatively in yellow. These warn the drivers to start looking out for debris and other hazards that may take them out of the race or reduce their pace.

If a driver is breaking any regulation while on the track, they light up alternatively in white. They also indicate a danger zone.
