I just got an '06 Altima 2.5 Special Edition last week.
The low-beam bulbs are the standard H1 Halogen. I want to replace them with better PIAA H1 bulbs.
The user manual says that the entire lamp assembly has to be removed and to take it to a Nissan Service Dept.
I decided to try and do it myself. I located two bolts on the top of the lamp assembly that hold it in place.
However, when I removed them, it feels like there is something more holding the lamp in place.

Can someone give me a step-by-step instruction on how to do this?
I rather try it myself than having to pay a service dept.

Also, how do you adjust the beam angle?

Anyone?
