The 1993 Firestone Indy Lights Championship consisted of 12 races and featured the introduction of new Lola chassis. However, this season was also unique in that included a separate "B-Class" classification for drivers using the previous season's March chassis. However, the B class was not a success, never with more than four entries and many oval races only saw a single entry from B-class "champion" Jack Miller, the only driver to compete in all twelve B-Class races.
Bryan Herta put on a strong showing in the main championship, winning 7 races and defeating his closest rival by 91 points.
