ah fog and snow, i worked for a water taxi company for many years as well as tugboats and personal boating and fog is certainly the nemisis, after trial and error we discovered that since fog lights are designed to work best low below your driving lights we would make drop brackets for the bow of the boat to get the fog lights as close to the water as we could and as far below the driving lights without putting them in danger of the water and what a difference it makes than mouting them on the deck pointed down at the water. above or beside the driving lights
so if you really want to improve visibilty yellow fog lights are a must but mount them as low as you can for best performance, if you mount them on the bottom of the bumper you will get better visibility than on top of the bumper this i discovered when my factory lights died and rusted out I mounted the baja walmart el cheapos to the bottom of the bumper and while it looked like crap it made a huge difference like on our boats, the only downfall is they get in a position to be hit when offroading but if you dont wheel or wheel alot i would suggest this....
