I want to replace the bulbs in my headlights (low beams) and my driving lights to Xenon bulbs. What are the best kits to go with?

 

I have these bulbs in my car. The brand I have is Plasma Industries. The quality is impressive, and there's a 10 year warranty on them.
Check out their website: www.plasmaindustries.com

Only thing is you can't buy them from their site.

I'm looking for a place that sells them cuz I need more, but I'm not going back to where I bought mine the first time.

 

Are those for 98+ only or will they fit say..my car?
