Like the front wing, the rear appendix will be a wider element by 100 mm with more depth. The changes aren't expected to have much of an aero impact however, except on high-downforce tracks, like Melbourne, Monaco or Singapore, where a greater DRS effect will come into play.
Rear wing endplate lights
With safety always at the forefront of the sport's concerns, F1 will introduce rear wing rain lights to help improve visibility when conditions are poor.
A vertical row of flashing LED lights - similar to what has been used in the WEC - will be mounted on each side of the rear wing and compliment the large center light located at the rear. The use of the light will be mandatory whenever a driver is using intermediate or wet tyres.
