Hi Jacob
As per rulebook secion III-C the vehicles must retain their main frame and drivetrain configuration (electric drivetrain).
If however, the team decides to change any part of main frame or drivetrain during the event, they will be allowed to compete only after completing the safety inspection for the changes made, also any scores awarded for the respective (original) design will not be credited to the team.
Both standalone and integrated lights are allowed and can be chosen as per the teams discretion.
