Hello, Mclaren and Callaway's endurance lights are not working for me. The other cars worked fine though.
I turned on the endurance lights for the Mclaren and Callaway and when I load up a track, it still has the sprint lights.
I personally didn't notice any problem with my McLaren and C7 but with the AI cars i saw that they were on sprint headlights. This is done because you have to also force the ai to use that upgrade.
