Touch Bar light is very dim

Hello sohrab90,

I understand that the Touch Bar light on your MacBook Pro is dim and you can't see the Touch Bar options. I am happy to help.

• Change the brightness or volume, or ask Siri: Tap the buttons in the Control Strip. For brightness and volume, you can also quickly flick left or right on the buttons.
• 
• Expand the Control Strip: Tap , or press the Fn key on the keyboard (if you customized the Touch Bar in Keyboard preferences to expand the Control Strip).
• Tap the buttons in the expanded Control Strip to access additional settings and macOS features like Mission Control and Launchpad, or to control video or music playback. For some settings—such as display brightness—you can touch and hold the button to change the setting.

Use the Touch Bar on Mac

Let me know if that resolves this issue for you. 

Thanks for using the Apple Support Communities. 

Take care.
