Kind of a dumb question, but in the very first post he mentions cutting open the headlights, I'm assuming he just means if you want to change the projectors or add one for high beams? Also for those of yall who've done this how hard would you say it is? I'm thinking of hmgetting the Hella ones but a little worries about the wiring since I've never done anything like this before, especially adding a circuit to the fuse box
