Flickering brake light

Picked up a used 2017 Ram ProMaster 2500 last year for my mobile workshop setup. Lately, I've noticed the brake lights flickering intermittently. Anyone else run into this? What should i check?
 
Flickering brake lights on the ProMaster are usually caused by a loose ground connection, a failing brake light switch or even moisture in the light housings. I'd start by checking the bulb sockets and grounds for corrosion, then test the switch on the brake pedal before chasing any wiring issues.
