does it matter on the brightness on the bulbs you put on the fog lights and headlights itself, or is there a limit to the amount of brightness it can be? same question to the rear lights.

 

you gotta check out the wattage, because if you have bulbs too powerful for your car you can melt or burnout your wire harnessing. If you want a certain set of bulbs that are too powerful for your harnessing you can always upgrade your harnesses.
