I like having fogs but the amount they're used I don't think they're necessary. The A6/S6 ones look awesome
....When I investigated DRLs on my Mk5 GTI I discovered that unless I changed the panels to the horizontal slatted grills like the GT has, the crash bar would have to be cut into for S6 DRL units. So, a no-no.
Because I live in an area where fog/sea-mist is common, I thoroughly tested my use of the stock fog lights before deciding that they were fairly useless in how much they helped - I use my Xenons dipped for fog.
Why is it that some cars are factory supplied with front fog lights and others aren't? Mk5 GTI and R32 for example.
