I didn't think it was too much of a big deal on my Prelude. There was a slight gap of darkness between my headlight beams and the foglight coverage. I didn't see any problem with depth perception.

I think using yellow fogs is okay, as long as like all OEM fogs, there's a cover on the outside of the bulb. The little APC fogs you can buy at Advanced/AutoZone/etc. don't have that. They basically just project the entire light out straight foward really blinding people. Those are worthless, they don't even accomplish what a foglight is supposed to do.

If yellow foglights are what you want, you need to get ones that actually accomplish the job.
