Had a heck of a weekend, my low beam and day-lamp burned out on one side and my fog lamp burned out on the other side. I was cruzing the web looking for replacement bulbs that would sine brighter when I stumbled on your site. After reading reviews my questions are: I have a 2001 Chevy Silverado; can I just use the silverstar bulbs as a replcement bulb without the x2020 headlight kit? Does silverstar make bulbs for my day-time running lights and Fog Lights. Thanks for the Help!
