How To: Adjust Headlight Beam Height

Here is the easy & proper way to do it as shown to me by Jens Heydel of Park Ave Acura.

All you need is a phillips head screwdriver!

These picture show you how to get to the gear you need to turn with the screw driver from a zoomed view all the way too close up.

Concentrate on where the arrows point and ignore the gold bolt that dominates these pictures... pay attention to the circled silver bolt/teeth in the close-up.

Once you find these "teeth" all you need to do is insert a phillips head screw driver and turn in either direction. The teeth I describe look like the spikes on a kings crown... I think it may even be called a crown gear or something of the sort.





This is the crown gear you need to insert your screw driver into. The object is to get the screw driver into the teeth... a typical standard sized screw driver is sufficient.


Finally... here is a picture of how the screw driver goes into the gear. Just turn right or left...



Yes, its that easy... whole process shouldnt even take you 60 seconds.

The hardest part is finding flat ground with a reflective wall to aim against. A garage door usually does fine if your driveway is flat.

No, this is for your low beams... the Xenons.

The reason you would want to do it is they often become aimed too high or two low... and this is a neccessity after any sort of suspension modification... especially springs.

The reason this was posted is because people keep asking how to do it... so now they know.

Well, further instruction then...

To do this...

Park your car on a flat surface facing a flat reflective wall. I'd say about 10-15ft away maybe?

When you turn your lights on you will see a sharp distinct line where the beam ends on the wall.

Mark this line as a place holder and make only slight adjustments.

1 inch above that line really makes a big difference in the height of the beam at a distance.

Look at bottom center of the following pic...

There is an embossed symbol on the plastic that looks like this "U <-> D"...



That tells you the direction to turn... if your facing the cabin of your car up is left and down is right.

But like I said... just mark where your lights are on the wall before you adjust them... and you will be able to know exactly what direction youve changed and how much.

Mark where your front bumper is too that way you can come back after testing your lights to adjust them further if need be.

grrrrr......i tried this and still my HID bulb refuses to budge. the drivers side bulb is still positioned much higher than the passenger side bulb....and its still annoyingly bright. when i clear out my headlights im going to try to lower the bulb manually (w/o touching it with my bare hands obviously). is that a bad idea? if that doesn't work its dealership time.... blah....

hmm. does the gear move?

if the gear moves and the light doesnt... then go to a dealer.

dont try to do it yourself... thats what a warranty is for.

just have them check it at your next service appt.

gear moves and light doesn't. guess i'll have to get it checked at the dealer. think they will give me crap if i have cleared headlights by then? Having a CAI doesn't void the warranty does it?

Yes they will prolly give you shit if youve cleared your lights... depends on the dealer.

Just bring it in before that.

And no, the CAI wont affect your warranty but it can give you trouble at the dealer if there is a problem that could relate to it.

your headlights arent related

I fixed it!!!! my headlights are stright now!!
I used a 10mm. and turned it to the left.
I also tried using a flat head, but that was for ajusting the lights from right to left.
For adjusting the light up and down. there is a 10mm bolt on the other side that can but turned also.
