Low beams do not work and bought the car with a salvage title and the dmv wantsa lights and brakes inspection to registar it. Any suggestions?

If you bought it from a used car dealer, it is their responsibility. If you bought it from a private party, it's probably on you. Say hello to your credit card or checkbook...

You still have to have the inspection, but check the fuses for the low-beams. They are separate from the high-beams

However, if the DMV says "you need this to register it", you need it to register it. They are probably going to ask for a safety inspection, as well. If you didn't make arrangements with the seller, then it's your problem. There are no "lemon laws" to protect you with private party used car sales.
