Help! Upgrade of bulbs and angel eye ring install
 

I am in the process of upgrading the headlights in my e36 318ti and need some help please. I have seen the bulbs but am not sure of the bulbs that I need as everyone tells me something different.

I have also purchased some ccfl angel rings. Can anyone give me some tips on how to fit them.

In terms of bulbs. I have been told that I need H1 bulbs for the fogs. H4 for the main lights. H3 for the inner/flasher lights. Is this correct?

I take it that I will need to disconnect the existing parking light in order to use the halo. How do I do this?

Thanks.
