Hello, I've been reading lots of posting on this forum, but this is my first time actually posting. I recently ordered a Blinder m-20 extreme, and mounted it on my 1999 honda civic, in the grill. I set them pretty darn level to the road, but I was wondering how crucial it is to have them 100% level, as I think they may not be level as the road slope changes, or depending on how fast you are going. Also, when I turn it on, it beeps and goes from red to green, so I'm assuming it is working? Thanks.
