I wonder why the 98-00 never got the green water stuff, i guess because our projectors actually move up and down internally.

the 98-00 LS has the green level on the NON-HID cars i believe. but ur right in that the HID equipped cars had Autoleveling, so the only way to adjust them to go higher or lower is conning a service tech into doing it for you.

Good write-up. Some additional:

The little bolt on the fender side of the headlight assembly is the vertical adjustment for the fog light. The fog can only be adjusted for vertical.

The main headlight, the adjustment **** is dual action and pulling or pushing it adjusts it either vertically or horizontally when turning it. There is an unlock tab you have to disengage before making adjustemnts. The tab is missing from PureDrifters headlight as pictured. So be gentle, our cars are getting older so these little plastic parts and gears are easily broken. If you peg the adjustment screw, don't force it, as you will wear away the gear teeth.

The green vials...are general guides but they aren't super accurate. Find a good wall and adjust to the beam charactersitics you want. BUT, there is limited adjustment and depending how the bulb is, the pattern changes. Take a dark towel and cover the headlight you aren't adjusting. This allows you to see how the beam is from the particular headlight. AND remember, go easy when adjusting. The plastic is aging so being too forceful may be a $$$ lesson if you need a new assembly.

Oh...cover the main headlight beam with a towel if/when adjusting the fogs.

Hello, recently someone hit my passenger side fender, damaging the entire headlight assembly. I was wondering when the body shop installs a new one, will the headlight auto adjust? I have a '00 LS400 with factory HIDS, thanks.

some adjustment will have to be made but the autolevel will help, on the 98-00 the headlight adjustment is different.

Default 1999 Lexus LS400 HID aiming

I have a 1999 LS400 with autoleveling HIDs and had to take it to the dealer after one headlight was replaced and wasn`t shooting right. Didn`t take long and was $61.**
