Whoever's done this, can you answer what this extra stuff is that came in each projector box? Or the nut behind the projector lamp mounting bracket (which just doesn't seem to serve any purpose)? Nobody has mentioned any of this in any guides I've seen.
The top four items I know what to do with. The screws and other things seem useless, but then why would they be included?
Edit: Also, should I have gotten 4 bulbs, or just 2? There are 4 bulb holes total, and I only got 2 bulbs. I'm assuming I use the OEM bulbs for the inside lights (high beams/DRLs? I don't even really know what the inside ones are for...), but then they won't match the other headlights.
