Why would the brake light and battery light stay on in a 1995 Nissan 200 sx while driving?

the brake light could be on for 2 reasons, first check your brake fluid level under the hood and make sure it is above the "min" line. if that's full enough, you will have to take off the cover around your emergency brake and there will be a small bolt with a rounded top under the brake lever. make sure it is at the right height when you pull up on the ebrake.
