I replaced the fog bulbs in my new '06 GT with Sylvania Silverstars-very good mod. I wanted a similar look in my headlights and since Sylvania hasn't brought out a Silverstar in the H13 bulb, I ordered a set from ImportsTuning. The bulb they sent me was a LUKS H13 bulb. This bulb is supposed to have the same color temp (4000K) as the Silverstar. I put them in and am disappointed, they look good, very similar to HID's, but from the drivers seat they look too blue and actually give somewhat less light on the road. I am really disappointed in Sylvania for not marketing a Silverstar for our cars.
