B&T VP9 and their Station six nine. Not saying it was that, but just saying they exist on the market today. So a welrod-alike can be had. But it would absolutely leave a paper trail as its a unique gun.

I would disagree. Factory, unmodified vehicles with factory fit LED lights are more often than not utterly blinding. Honda models come to mind first. Stellantis, especially Ram trucks (again, not the lifted or modified ones) and Cadillac SUV’s are all painfully bright from the perspective of my average height Station Wagon.
