I wouldnt get hids in your foglights, it might reduce their effectiveness when you need them lol
I haven't got foglights on my current Grande and when it's foggy, which is all the time because I live on a river by the sea, I can live without their functionality
The cornering function of my new cars fogs is the only use for them for me really. So if there switching on every 5 seconds round corners I want them to match the headlights. Think I'm gonna stick to blue tinted xenon gas charged normal bulbs for both fogs and headlights.
Would look ghey if they were different to the headlights with the amount they will switch on round corners lol
