Just driving along and all of a sudden the battery light and parking brake light come on at the same time. Car still charged after 12 hours turns over okay. Major or minor issue do you think? Would appreciate your advice.

Welcome to 2CarPros.

I suspect that the alternator isn't charging. The battery, if in good condition and fully charged, will last a while before failing. With that in mind, I need you to check the alternator for output. It is very easy to do. All you need is a volt meter or multi meter.

Follow this link:

Here are a few links to help in general:

If you feel the vehicle is running properly, most parts stores will test the alternator output as well as load test the battery for free. You may want to do that.

If you perform the above test and find the alternator has failed, here is a link that shows in general how to replace one:

Here are the directions specific to your vehicle for replacing the alt. The attached pictures correlate with the directions.
