Today while driving in fog (by compulsion not by choice) I realized the importance of the pair of yellow BOSCH fog lamps fitted in the front of my car. After a little roadside adjustment of the beam angle, i was able to drive in fog with a lot of ease. I kept the main beams switched off.
...and these lights, which otherwise looked useless with its low intensity light, really made the difference today.
