So I took my headlights apart today. I took out the projectors from both headlights (the whole projector, not just the lens) problem is I didn't make any markings on either and mixed them up. I notice all the markings were the same on both except one said "1" and the other said "2". I tried bolting both up, and then switched them and bolted it up so they line up perfectly either way. Does it matter? If so, which is 1 for and which is 2 for?

TIA
