These Ion Yellow fogs lights are actually what I consider a fog light to be. They not only have a great appearance and are much brighter than stock but in actual fog situation they are night and day over a white bulb. I will put these in every car i own !!

<p>These bulbs are super yellow but bright as daylight. I'm not sure they are DOT approved for low beams. But, when paired with ion blue head lights, (I think that's what they were called) you get the full spectrum at night.</p>
