What I love seeing is people driving gray or silver cars around, in the rain, when it's foggy, WITHOUT their headlights on. Brings a wry smile to my face.
Um, why would anyone accept those conditions as 'safe'?!?!
It's like they're begging for a head-on collision.
If nothing else, might save you some insurance $$$ in the long run.
To wit:
I converted my 6000lb 1977 Dodge M880 5/4 ton truck to all-wheel disk brakes a few years ago, after I couldn't stop in time for someone who stopped suddenly in the middle of the road in front of me to make an unsignalled left turn. That little nasty jacked my insurance up about 3X. I was then paying about $800/yr, for straight liability and medical. Now, years hence, I've been LUCKY enough to stay accident-free. My current rate for the same coverage? $360/yr. The savings in the FIRST year covered the cost of the disk brake swap, plus interest.
I mean, what would stop any intentional driver from just reaching down and flipping the headlight switch on? And, just about every car made in the last 8 years has a switch position that AUTOMATICALLY turns on the headlights whenever the car is running!
I think some people believe that having the lights on stresses the battery/charging system (PHFFFTHTT!).
In all fairness, the amp draw of the new LED headlights is a tiny fraction of the old headlights. [My M880 has aftermarket round LED headlights.] This DOES make a huge difference to the old-style analog headlight switches. That amp-draw creates heat in the switch, which begets corroded contacts. And, then, more heat due to added resistance at the contacts caused by the corrosion. Can be enough heat to cause a fire under the dash. Not an issue with newer vehicles.
