1. In most modern cars, turning on the headlamps will dim the instrument cluster and or LCD display of radio or MFD. For example, in Optitron-equipped Toyota models, the instrument cluster becomes really dim if you so much switch on the pilot lamps or headlamps.
2. Energy saving - read somewhere that switching on the headlamps consumes about 300w of power, compared to about 30w for LED DRLs. This translates to higher fuel consumption, and possibly more wear and tear on electrical components of the car.
3. On the road in daytime, I try not to have my tail lights on (can't be helped if you switch on your headlights) as I feel this makes the brake lights less "obvious" to vehicle behind me - which means higher chance of being rear ended.
4. Again, I feel that in day time, switching on the headlamps makes the front turn signal lamp less obvious to opposite traffic.
5. You have to manually switch on your headlamps, which introduces human error (in this case, one forgets to switch them on).
1. Yeah noticed this, but isn't it due to the fact that the car thinks that you are at nighttime? but your point stands, that the instrument would dim during day time, when you need them to be bright due to the glare.
2. What about the pilot light? need to find out about this
3. fair point, i havent thought about that
4. fair point
5. yeah, and even in modern cars with auto on headlight will not auto on during daytime for obvious reasons.
OK I see the point of actual DRL
