lights dimming

thank you very much i will upgrade my alternator so i don`t have to worry about it in the future

For the fog light fix, did you use a relay? I know on my older car it has a bimetal thermal overload. So when you have the lights on for a while with the increased load, it gets hot and opens the circuit. Until it cools and then restets itself. Like an auot reset breaker. If you hooked your fog light directly to your low beam this could be the case. Use a relay and take the power from your battery, don't forget to fuse it. Also make sure you have a good and secure ground. I've also seen some really cheap fog light that the bulb isn't actually that secure in the socket and the constant vibration of the car would cause similar symptoms. Good luck!!
