American Kyle Kaiser driving for Juncos Racing led a steady campaign where he finished every lap of the season in a season where no particular team or driver was dominant and in doing so essentially clinched the championship with one round remaining (he only had to start the final round). Kaiser won three races with an additional three podium finishes. Santiago Urrutia struggled during the first half of the season but logged six podium finishes in the last seven races, including two wins, to vault his way to second in the championship. Colton Herta won six poles, but was only able to convert that to two wins and he finished third in the championship. Brazilian rookie Matheus Leist had a brilliant stretch of races in the middle of the season, capturing three wins, but was otherwise unremarkable and wound up fourth. Zachary Claman DeMelo won a single race and finished fifth in points while 2016 Pro Mazda Championship winner Aaron Telitz bookended the season with his only two wins and finished sixth. Nico Jamin won three races but also suffered four DNFs and fell to seventh in points. Juan Piedrahita captured his first Indy Lights pole at Gateway Motorsports Park, his 57th Indy Lights start.
