The automatic range adjustment isn't necessary on these Xenon/Hid-headlights due to being only a 25 Watt Xenon/HID (D5S) bulb (you don't have to have "headlight-sprayer/washer either).Though the headlight range adjustment system might be an issue, particularly for those of you int he UK who have to go through MOT inspections...
Don't know if this is a problem with the new LED-headlight, but if the switch is an indicator (it has manual adjustment, which is never combined with automatic adjustment) that's not a problem either.
This is based on the regulations we have here in Sweden, which usually is in line with the most strict regulations.
My guess based on my work is that switching to the new LED-headlight is bolt on, however, I don't recall seeing the option for "LED headlight" in AlfaObd. I will have a look when I find the phone that have the software installed....
As stated in my thread, the dealer most likely can't change the software-setting due to some limitations set by Jeep/Fiat.
Biggest problems are prices, a pair of new Xenon/Hid-headlights are roughly $1 200, and I guess the LED:s aren't cheaper.
