Going for a really bright, high-lumen output fog light makes sense if you live in an area that gets really dense fog multiple times per year. On the other hand, if you live in an area that does not get fog or any other visibility-impairing weather conditions, lower-output fog lights are going to suffice.
Contrary to popular belief, a larger fog light does not always translate to more visibility. The reality is actually really different as wide and long rays of light can actually lower your fog visibility. Try to go for a size that is recommended and tested for a Bronco Sport as you don’t want to make this mistake.
Most fog lights out there are either white/bluish or yellow as those are the colors mandated by the US government. Whatever you do, do not go for red fog lights as that can confuse other drivers into thinking that they are looking at the back of a car. Yellow fog lights are usually the best as they cut through the fog better than white or blueish lights.
