Hi, I just bought a used 2017 Tahoe and there is a **** next to the headlight control I do not recognize and the salesman was also perplexed by. Picture attached.

Does anyone recognize this?

Almost looks after market - maybe for the flux capacitor??
BTW, Welcome to Chevy!

Thanks! Haha, yes very flux-capacitor-esque and definitely seems after-market.

I did a reverse image search and found the same exact thing in a listing for a 4-runner but without caption. I have turned it and pressed the button and cannot detect it doing anything. Seems to light up when I brake. Really odd! Hopefully some hero out there knows what this is

that's hacked in.
What does it do? crank up the gigawatts?

If it lights when you brake maybe it's for trailer brake control
