The stock marker & turn bulb holders lock into the back of the headlight housing below the main bulbs so it's almost sealed. I labelled the bulb positions with their bulb types.
Low Beam - H7
Hi Beam - H1



Note the galvanized adjuster screw at the bottom of the screwdriver channel. I added white paint pen to its Up/Down labels. The screw head is both a hex (8mm IIRC) and a #2 phillips with a large integral washer whose lip is serrated so that it can be driven at a right angle by a long #2 phillips. That's why it's set into that channel - to keep the screwdriver shaft in-place as adjustments are made to the low-beam's vertical alignment. Horizontal alignment isn't as critical with projectors. Alignment isn't as critical for the hi-beam.
