The DRL debate rages on sort of......Nothing to do with bulb longetivity.
If the DRL had a dramatic benefit I might be on board......trouble is, the majority of other manufacturers don't provide it in the US and I don't see any more 'other brands' wadded up more than those with the system.
I remember back in the 70's, it became compulsory to operate a motorcycle with the headlights in operation....I cannot, to this day, determine if that helped one bit......left turns in front of me as well as driveway pull outs seem as frequent as ever.
I contend a driver actually paying attention (that means, quit looking at the phone/radio/stars/moon/GF/lady on the sidewalk/yada yada would help and since they aren't looking where they're going I could mount a operating lightbar and they won't see it in their lap.
Remember, these are the same folks that turn in front of police cars and fire trucks.....lights and sirens........or turn in front of a tractor trailer.
If they survive the ordeal, the story is the same....."I did not see it" is what is said as opposed to "I wasn't looking".
All of my sons trucks are set up to operate, 'All Lights On'......when I'm driving one, I must be invisiable.......Black with red fenders, lights on, says Peterbuilt....still get a oncoming left........they look at me (finally) when they can hear the trailer tires dancing......and then some of them flip me the bird.......cause my presence scared them I guess.
But, for my own car(s)......I just prefer them off.......
