where in the hell, in that hole is it? angled or straight down? i looked after removing the plastic cover and i couldnt find it.. my driver side is slightly higher than the passenger side. TIA

 

better off leaving the cover on, you dont need to remove it. the cover has a slot where you can slide a screwdriver in. and the hole is angled

 

thanks! now i have to go buy a screw driver long enough and with the proper teeth to turn the screw (8" #1 screw driver?)

 

hmm yea a clear explanation of which type of screwdriver needed to adjust the lamps woudl be appreciated...

after i did my lights i know it's off and probably a pain in the ass for oncoming drivers

 

ok. ill take pics tomorrow and let you know what screw driver i used

 

Ok, so maybe i DONT need to adjust my headlights. i was able to take a pic (that i cant put up at the moment but you'll get the idea) in my parking garage at work. i THINK this is normal. it looks something like this (of course over exaggerated):

This is the low beams only. the high beams looked pretty cool too, lol.

 

Photo of headlights (i was on a SLIGHT decline, as you can tell from the parking deck and the angle)

 

That pattern is correct. The left headlight is lower so it doesn't blind oncoming traffic.

I just bought an 07 TL-S and noticed the same pattern. It seemed odd b/c my previous car (97 Accord) didn't appear to have the same alignment mismatch. I concluded that the left beam was lower to avoid blinding oncoming traffic (mostly so I would stop worrying about it). Glad to see that it is apparently standard.

 

thanks for the info, mine are aligned with that same pattern. the left is a bit lower than the right one.

 

As was previously said, the driver's side is aimed lower due to oncoming traffic. Additionally, the passenger side is higher to illuminate road markings/signs.

I took the stuff below from a post on HidPlanet.com.

DOT cutoff has a short slope between the cutoff lines, this allows them to be aimed higher without blinding traffic. The DOT design also incorporates a way to let small amounts of light out above the cutoff to reflect off road sign on the right, as you can see from the faint upward flare of light. Here is a DOT valeo projector cutoff.



ECE also known as E-code is what they use in Europe. Alot of these projectors have different bowl designs and can offer increased light output based on the design. The most important part of an HID projectors performance comes from the bowl. The lens can be changed to make a sharper cutoff with clear lens, but the actual output beam is controled by the bowl shape behind the lens. The cutoff also has a much larger slope, and there is no light above the cutoff because Europe has lit road signs. If you use E-code projectors in the USA, they must be aimed lower so they don't blind traffic. Here is a cutoff from the E46 BMW M3 ECE projectors.
