Sorry if this has been asked multiple times.
I have ordered a pair for 5900K Xenon Halogen Lights
Do I need a conversion kit to run them on the stock mustang set up?
I drive a 2008 Mustang V6 Premium

 

Followup question: What white lights can I get to run on the stock set up? (without any conversion kits)

 

Xenon Halogen bulbs are simply halogen bulbs with a blue tint or gas filled to give the appearance of HID lights. These bulbs don't use ballasts or igniters; just plug and play. The downside is their longevity. For white lights check out Silverstars (4300k - 5000K).
