I believe the wattage of the stock fog light is 23 watts.
Don't want to start an "illegal versus legal" debate, but from what I understand, using the Rigid (or similar) type of light is for "off road use only". The only reason I mention this is because you said "not being able to see the lines on the road".
I don't think the BBL lights, in those housings/adapters will allow you to run an amber color.
I was going to try to run these bulbs as my fogs
to see how they'd work out. They get mixed reviews, but at that price point, I think it may be worth a shot.
