>> I want the most lighting I can have at night
Though looking great from outside as car decorative feature, in my experience, fog lights are not designed to provide any 'proper light'. They will only add some value 5-10 meters in front, which is not where I need extra light. I don't know who designs this stuff or perhaps something is wrong with my eyes
The only option with 'more light in right place' than my xenon pluses is when I switch to high beam. But that, of course, doesn't help drivers ahead of me.
And yes, Xenon Pluses are just great. I've seen brand new sets available on German eBay for under 1000 euros recently. You will love them!
P.S. I like yellow colour of your foglights. Did you put any specific bulbs there?
