Thanks for the responses. VLED has 20% discount through 9pm PST tonight, so I ordered the MICRO EXTREME H7 6K low beams and MICRO LIMITED 9006 HB4 3K fog lights.
I am a volunteer ski patrol in the NC mountains -- we had super think fog this weekend, which made me decide to go for the 3K fog lights. VLED only offers the 3K light in the MICRO LIMITED model (i.e., 2500LM vs 3500LM produced by the MICRO EVOLUTION).
For the low beams (H7), I thought about getting the 5K, but went with the 6K. I had purchased a set of XSTORM H7 LED from Amazon about two weeks ago, as I liked the idea of 6 sided / 360 degree LED, but I have not had a chance to install them yet. I have a 2006 WRX, so I will use the XSTORM H7 LED's in it -- they will replace an older set of HID's that have been acting up recently.
I ordered the LPR 1800LM LED REVERSE LIGHT SYSTEM as well for the WRX, so I will be all lit up both coming and going for both cars now... ;-)
