I have had an HID kit in my 2016 for the last year. I got it form XENON HID . com. Simple clean plug and play kit. Went with the 5000K bulb and 55w ballasts. It has been working well, until recently. The light is obviously brighter than the halogens. Even after I upgraded the stock halogens, the light was better but not great,and I was only getting about a year out of the sylvania bulbs I was running.
In the last couple of weeks, I have noticed that my driver side HID is acting up. It sometimes takes two on/off cycles of the switch to get it to light, and it is also has a slight purple/pink hue to it, which means it is dying. I have priced out a replacement pair, and they are at least double the cost of a high end halogen pair.
I do like the light of the HID, but for $65-85 cost, compared to $30 for halogens, I am going back to the halogens. It seems I will get about the same life span out of each them and for half the cost and the simplicity of the stock halogens, I will do with slightly less light.
As for LED's...I know that LED lights do not throw light downrange as far as HID or halogens. The light diffuses sooner, although brighter and draws less power at the source, which translates into less visibility. Check youtube for info on LED lights. Lots of videos comparing them to the other options.
