2 HID bulbs,
2 15watt (Light blue) fuses
3/4" drill bit
This install is very easy, and probably won't take you any longer than
I started with my driver side..
Since you are dealing with some expensive bulbs, I would highly recommend
loosening your headlights to give you some room to work with, which is what
I did. Now I have access to professional aiming devices so the cost of
getting my headlights aim is not a worry of mine, but if you do loosen your
headlights, yes you will have to get the aimed again.
See how much little space you have to work with...
And how much more is created just by loosening the headlights:
So, that said.. I loosened the driver side headlight and pulled it out just
enough to give me some room. Very easy, 3 8mm screws, two on top of the
headlights, one between the turn signal and headlight.
Once that done open up the rear of the low beams by taking out the
protecting cover, take out the existing bulb and replace it with the new hid
Now, take the cover and we'll have to drill it. DO THIS AT YOUR OWN
RISKS!!!! I have LOTS of drilling tools so this was easy for me to do....
I first tried to use a wood drilling bit...
Didn't work as good as I wanted it to, BUT it's perfect for starting a hole
Then I took out my "MAC DADDY" drill bit
The hole only needs to be ~ 3/4" look at the gasket that is right behind the
hid's it should be a bit smaller than it.
And this is what it's supposed to look like drilled and with gasket
Then connect all the wires, unless if you're trying to, you cannot go wrong
in this step, and if you do... humm... maybe you shouldn't try this
Put the headlights back on, make sure the gaps are even all around.
Before turning lights on!
CHANGE THE FUSES!
Since I did it one headlight at a time, I changed the fuses one headlight at
a time, if you want to do replace both headlights at once and then start
them, then replace both fuses at once:
But just in case:
Your driver side low beam is protected by fuse #11 , and the passenger side
one by fuse #12
Now, it's the same exact thing for the other side...
Once you're done with all this, get in the car, and turn those new suckers
on and ENJOY:
