High Quality Content by WIKIPEDIA articles! The 2008 Indy Racing League Firestone Indy Lights Series season, formerly the Indy Pro Series, began on March 29, 2008 and consisted of 16 races. Due to the discontinuation of the United States Grand Prix at the Indianapolis Motor Speedway, the series lost its Liberty Challenge double header typically held that weekend. The Liberty double header were replaced by the addition of a second race at the Mid-Ohio Sports Car Course and a return to the Kansas Speedway, where the series has not raced since 2004. All races were shown time-delayed on ESPN2. Live stream video was available on the IndyCar Lights Series website. It was announced on March 22, 2008 that Firestone signed on to be the title sponsor of the Indy Pro Series, and thus the series was retitled the Firestone Indy Lights, in reference to the old Indy Lights development series which ran under CART from 1986 to 2001.
