I'm searching now but after a very cold day with some snow my batt light and p-break lite are now perm on. I ran some checks and by pulling the 4j connector off the alt the light's go off. Which seems to point to an alt problem.. But the car is running fine for several weeks as it is (lights on).

 

get to a parts store where they can check the battery and alternator for function- the starter for acceptable draw during use, cable condition etc
Its all free too
They will not tell you to buy parts you dont need- they only want to sell what you need

Things to look at for you- age of battery
amount of time you use the battery for stereo with engine off

DO NOT drive around with a problem- that just makes the repairs more expensive
