    How much is "too" much? I'm completely new to lighting and electrical. I want to put some lights on as well.

    "To much" would depend on the size of your alternator vs the amp draw of the lights you want to use.
    Example:A pair of 130w lights would draw 21.67amps.(divide the total watts
    of the lights by 12 =amps draw)

    Do you do a lot of off roading or are they just for looks?

    how many amps is a second gen 4 banger good for? and how many does it draw stock? ie. how many can you add before you need to consider an aftermarket alternator?
