You don't have to touch them at all. Remove headlight by pulling up on the two tabs holding each assembly. Remove bulb connector and twist and remove bulb. Replace in the opposite order. Bottom line do not remove the silver covers. They stay in the assembly.
That's how it is on a generation 1. If I'm wrong please chime in.
You just take out the old bulb and put in the new. Don't have to mess with any tips....just remember not to touch the glass of the bulb when you put in the Silverstars.
That's what I put in mine.......big difference from the stock bulbs.
I also replaced my fogs with the Silverstars as well.
