What does this sentence mean?
Okay, I'll sweeten the deal. I'll throw in a lighted mirror on the visor.
Thanks a lot
The visor is the shade that pulls down to shield the driver's and front-seat passenger's eyes from the sun when it is low in the sky.
There is usually a mirror fixed to it so that when it is pulled down you can check your make-up.
A luxury feature in some cars is that this mirror is illuminated, or lighted, for use after dark.
To throw in means to supply for no charge.
Also known as a "vanity mirror."
