I don't use my auto lights for that reason, and I always have my lights on regardless of what time of day (with the exeption of when the sun is very low - makes it harder to see you than easier as the bright lights may blend into the sun when people are looking in the direction of the sun)
When the fog is bad enough to require front facing fogs, you are supposed to drop to sidelights and put the fogs on, the theory is they cut under the fog whereas the dipped beam reflect back at you off the fog:
Front fog lamps
A pair of yellow fog lampsFront fog lamps provide a wide, bar-shaped beam of light with a sharp cutoff at the top, and are generally aimed and mounted low.[10][11][12] They may be either white or selective yellow. They are intended for use at low speed to increase the illumination directed towards the road surface and verges in conditions of poor visibility due to rain, fog, dust or snow. As such, they are often most effectively used in place of dipped-beam headlamps, reducing the glareback from fog or falling snow although the legality varies by jurisdiction of using front fog lamps without low beam headlamps.
Use of the front fog lamps when visibility is not seriously reduced is often prohibited (for example in the United Kingdom), as they can cause increased glare to other drivers, particularly in wet pavement conditions, as well as harming the driver's own vision due to excessive foreground illumination.[13]
The respective purposes of front fog lamps and driving lamps are often confused, due in part to the misconception that fog lamps are necessarily selective yellow, while any auxiliary lamp that makes white light is a driving lamp. Automakers and aftermarket parts and accessories suppliers frequently refer interchangeably to "fog lamps" and "driving lamps" (or "fog/driving lamps"). In most countries, weather conditions rarely necessitate the use of fog lamps, and there is no legal requirement for them, so their primary purpose is frequently cosmetic. They are often available as optional extras or only on higher trim levels of many cars. Studies have shown that in North America more people inappropriately use their fog lamps in dry weather than use them properly in poor weather.[14] (wikipedia)
Yes there is an indicator light on the dash panel but i do struggle to see it, in the daylight, even in the dimness of the fog it doesn't really show up.
