Here's my deal . . . first time I was in the dark, I had just changed my right bulb. Put it in (H-7) with tab to the top (the other one was installed like that). Nope, wrong way. Looked at diagram in manual and the bulb tabs were placed on an angle (going in at 7 o'clock) and noticed that the plug ins were at that angle too. So, put them in at that position, turning slightly to 7:30 o'clock and presto, that's how they go. Then back to getting the crossed-eyes adjusted. Went with the phillips for the bottom adjustment (oh, by the way, used a small drill driver on slow cause mine needed a LOT of adjustment. Bottoms are for "up and down" and top adjustment screws (done with 1/4" drive 8mm with a 6" and 8" extension with a universal swivel in between) are for left to right. And note from diagrams the direction of the arrows for proper movement. I've reached a good level of up and down but I think the "shutter" is ridiculous. Going into a curve at night leaves the apex in the dark. I've got the dims so high that I anticipate a lot of flashing lights back at me. NOT my favorite headlight system, shuttered projectors suck.
