Sounds like the alternater is on it's way. I will add something to this. I messed with a couple of alternator replacements but the last time the warning lights started coming on, I pulled the plug out of the alternator and gave the contacts a good cleaning both on the wiring harness plug and the socket of the alternator. You don't have to pull the alt to do this (at least on the '90s pickup) although it is hard to get that dude out of there. Anyway, no more problems. Actually, I have found on Toyota and Nissan both that anytime a warning light comes on it is very prudent to disconnect the suspected part (sensor, sender etc.) and make sure those contacts are clean. This has saved me buying and replacing a Nissan alt, a Toyota A/C compressor and a couple of O2 sensors on my personal vehicles and the advice has saved a few friends some expensive repairs too. Definitely worth the cost of some contact cleaner from Radio Shack or the parts store and the little labor to disconnect and clean the connectors.

What might be wrong with a Mitsubishi Galant if the lights only turn on when the driver hits the breaks?

Are you talking about ALL the lights, or just the dash lights? If it is just the dash lights, you might have a bad ground for the dash electronics, or bad connection at the Dash Dimmer control. But if you are talking about headlights, too, check the gound wires on the battery... perhaps wiggle them around until the lights flash. The brake light switch should not do this. It only controls the back lights. if its only the dash lights lighting up when you hit the brake, check the brake bulbs and make sure that they are the correct bulbs. (dual filament) and that the base of the bulbs contacts arent touching

well if you have allready cheaked the brake fuse it could be that the bulbs have burnt out check that.......As for me we tried to go the easy way with installing a toggle switch and manually turning them off and on, but today the wires melted completely from the battery to the brake lights themself, as of tomorrow we are going to buy a brake light switch and install it. I was told that is what is causing all of this trouble. I hope I helped.
