After market brake lights

[CoachH]

My 15 year old daughter and I are restoring a '54 Chevy Pickup for her first car. I'd like some added safety features and am wondering if anyone knows of a good place to find an aftermarket brake light that I can mount in the back window of the cab. I'd like to find something similar to what newer cars have nowadays where there is a 3rd brake light in the rear window.

Im also looking for side mirrors that have the same round look of the early 50's but maybe larger that the stock ones.

Yep.... Im a little protective of my little girl! But super excited she bought a classic truck for her first car.
