Follow Up and a couple Qs
I received my Quad HID Projector retros from Retroshop.us last week (there's a whole story to tell about FedEx at a later date). I had Friday off so I installed them plus the switchbacks I ordered. I've not been out driving after dark yet, so I cannot say much, but I have a couple questions.
Where I live, it's hard to find a level spot with a nice surface to project onto for alignment... so before I started the replacement I marked the position of my OEM beams on my shop door at a known distance of 16'. Right beam was about 2 inches above the left one.
Why do the light patterns on these new ones "zig" up and to the right on both beams?
sorta like ____/------
Which of these "levels" is used to adjust the light angle (not knowing better, I split the difference).
How much higher SHOULD the right one be?
I'm thinking about rigging up a deal where I can create an artificially "level" surface by running a string from a known point on the rear wheel, all the way to the shop door, with the string passing over the same known point on the front wheel. Did I read correctly somewhere that at 25', the beam should be 2" below the headlight's height? What is the reference point on the headlight it should be 2" below? Top, Bottom, Middle?
Thanks!
P.S. My dealer doesnt have an aimer... they pull up as close to their wall as possible and turn the adjuster and eyeball it a couple inches up or down, based on whatever the customer is complaining about (poor lighting, or drivers flashing them).
