walls can be tilted

 

Good call. I actually thought of that, but not until after I posted. I was hoping no one else would, either I failed.

 

[Forum Jackass mode] Ever seen the leaning tower of Piza? You think those walls are "vertical"? Have you seen buildings after a mild to moderate earth quake? You call those walls "vertical"? How about older buildings that have settled badly? You call those walls "vertical"? Maybe he's going to park in front of a poorly built fence. It may not be "vertical", either? Geezus H. Fricken Murphy! I'm trying to help the guy out and you're trying to argue semantics with me? How about coming at me about the "flat" wall statement? Aren't all walls "flat"? You wanna tell him to go do this against a stippled wall? We're talking 2.1 DODDAM inches, here. You wanna try and measure 2.1 inches on a wall with bumps on it? [/Forum Jackass mode]

OK, done. Ya know I love ya.

Ouch...I've been told
I will get you on something sometime. You'll slip up and I'll be there to throw it in your face

Good info on the headlight adjusting though for those who don't know.

 

I would make another thread but ...


I've searched here and I couldn't find out if people adjusted their headlights after lowering their car, or if you had to do it.

 

If you lower the car evenly (as in the same front and rear), the measurements won't change. You would still be 2.1 inches below the actual height of the center of the lens. If you lowered and changed the angle (attitude) of the car, then you need to re-align the headlights.

 

Thanks.

 

But would the angle not have to change slightly to project the light as far as it did before? Maybe say 2 inches instead of 2.1 or something stupid like that? If you lower it evenly the angle would stay the same, but the light wouldn't go as far...

 

It's all based on the initial angle, so 2.1" would be the same for a lowered car as xviper said.

 

The 2.1" is based on the attitude of the car. Granted, any lowering will only be about an inch or two anyway, so we're not going to get into a situation where the headlights are going to be a few inches off the ground (in which case, your notion would have some bearing on the situation). If you angled it up to shine the light on the same landscape as before, if you were an oncoming car just beyond that landscape, the lights would be shining in your eyes. We're already making oncoming traffic think we're on "brights", so this would not be such a good idea. If you look at your headlights on a wall, you will notice that the bottom edge is sharp and distinct and the upper portion of the cast beam is more broad and difuse. A car lowered by an inch or two (evenly) won't affect the illumination of the landscape in a detrimental way. Of course, I'm talking about the low beams (HID). If vast illumination is required, we still have the hi beams. Low beams are more for us being seen, moreso than for us to see, although both are important.
