Okay, back in the day, when you had to replace the entire headlight, you could go and adjust the lights direction. Up, down, left, right, etc.
With the newer models, where you replace the bulb, is there any way to adjust their aim? I have a 96 Geo Tracker (stop laughing) and the lights seem to aim a bit higher than I think they should. But, I dont know how to adjust them, or if it is possible.
I usually suck it up and ask the guy at the auto parts store who "legally can't help me due to liability" (who then tells me exactly how to do it, offers me tools, and watches helpfully from the front door of the store as I make repairs in the "do not make repairs here" area called the parking lot.
Willful ignorance of science is not commendable. Refusing to learn the difference between a credible source and a shill is criminally stupid.
Given that you don't know a Unix already (I'm assuming this from your post, feel free to correct me), that you're using "legacy hardware" (i.e. slow as balls gear)
