What is causing my headlights to turn off & on while driving ?

What is your question?

New battery, alternator, headlight switch, headlights, been in shop over last 6 months w same issues! Gear shift cable replaced to! Help! This is horribly hazardous!

What makes this problem better or worse?

It’s random, seems to happens when using blinker to switch lanes or turn onto a road and drive a few feet.
