I own a Jeep Wrangler with clear fogs and use them only when driving at night with little traffic. Mine are very useful because they light up the sides more so that i could see deer faster. And this has happened and saved me from hitting a deer.
I used to use my fog lights all the time with my low beams on until i started to notice how bright the other jeep wranglers lights were when the fog lights were used and approaching them. Not needed in the city!!!
There should be laws prohibiting their use in the city.
Have respect for other drivers, and if you blind them, you are only increasing the chance of them hitting YOU!
