On the topic of HID...
I have original circa mid-2014 HIDs in my S and about 150,000km on the clock. Headlights on probably 50% with my driving mix and latitude for daylight hours.
These were the best by far headlights I'd ever got on a new car, back then.
I am envious of the super bright whiteness of my wife's model 3 headlights and what they do for short range is noticeably better than my HIDs. I can't unsee them. They make my HIDs look yellow and dim. Which got me thinking... is there a lifespan of HID bulbs that I should consider to replace them?
I notice when they first come on, when they strike up an arc there is a very bright flash like a flash bulb, then they settle down. Over time, do they settle down further and further and in slow decay... so as you might not notice them fading over time?
New bulbs? Stock.. ?
Different bulbs? Higher brightness option?
New HID controller? Higher power option?
Anybody hack add-on LEDs somewhere on the front of the car.. best of both worlds (?)
Thanks for any ideas of actual light output mods for model S you may have encountered.. I'm pretty happy with the look of the headlight housings themselves.
