Does any one who did HID headlight adjustment can tell me which cut line should I have to measure for the height ?

I used 'HyperSprite Tech' website

For 06 and up 350Z has different projector which gives you different shape of cut-off line. There are bottom and top cut-off lines.

This guy said that measure to the Hot-Spot with 26". I don't know that hot-spot will be the bottom or top cut-off line.
So which cut-off line should I use to measure the height of 26" ?

Thank you.

 

If your looking at the cut off beam...the left side should be lower than the right , to avoid blinding incoming drivers. Im assuming 26 inches would be the same level at the headlights from the ground...so go with the right line.

 

thank you for your tip. Right I knew that the left side of headlight should be a little lower than the right side. However, I have question about measuring the height of the beam. To measure the 26" height, which cut-off line should I measure? 'Bottom' or 'Top cut-off line ?

Thanks

 

Do it from the middle, make sure your car is pretty far away.. say 100ft or so,

 

100ft will be too far lol
the best way is 25ft from the wall.
If you can't, 8ft will be okay too.
You said "go with the right line". I guess that is top cut-off line

 

thanks alot. helped out perfectly
