IMO, fog lights are usable ...in foggy condition. I used to live in San Francisco and when it's foggy, the headlights would be too scattering and blind others. Fog lights really helped. Driving lights (can also be placed in fog light location) are usable in dark condition when you need a little more light. I had a set of PIAA 1100 more than 10 years ago and still remember how bright these were. I had them on my Runner and even big SUV got blinded by these lights. I only had them on when I was in dark zone and noone was near me.
For the GS, esp with the self adjustable HIDs on luxury model, unless you live in a foggy area, fog lights are more for look IMO. It may give you a little more light but really insignificant compared to the self adjustable HID. I'm very happy with the VLEDs. Every evening when leaving the office, I drive through and into some stores with glass front. It always puts a on my face when I look into the glass. I too prefer complete fill vs the rectangular. But I guess fashion is what that is different. Or people say whatever floats your boat.
For those who want to know how the VLEDs look, here is a shot I took the other evening.
bnlexus, what bulb did you get from VLED? Did you replace the halogen bulbs with the VLEDs? And use the same housing for the new VLEDs, right? Thanks.
