can you just plug in different bulbs? for the xennon lights or road lamps? Are all of the upgrades really involved? (dont like to wrench)

 

What do you want to do? You can't make the low beams any brighter. They are HID, that's not bright enough for you?
You can change the color of the HID to a more blue with different 6K kelvin bulbs, but they won't be any brighter.
The high beams you can put in better bulbs. The road lamps as well.
Nothing is that involved.

 

I like my HID's i dont know why would u want a brighter

 

any recommendations for the road lamps (fogs)? preferably something cheap and easy
