Dispatch App Rebranding

Main goal and my role: Redesigning logo, sign up/log in page, User experience/UX/UI design, navigation flow, interaction design, log in page low fidelity, high fidelity design, Figma, Illustrator, Figma plug ins.
The most rewarding work - why? Have you waited tow truck on freeway or middle of no where in mid-west?
This company want to improve customer's waiting time and provide better communication between drivers.
Stake holders keep telling me no pastel colors, drivers need to see the message at night and able to read.
Design solution: Dark mode with color panels to distinguish message from other drivers or dispatch towers.
