Interestingly, the older HID headlights seem to have a higher intensity, more even spread and superior reach (check out the objects in the far distance beyond the bollards), so they may actually be more suitable for open road driving.
The LEDs have better clarity (ie. everything looks sharper), so they are probably more suitable for city driving where you need to be able to read street signs clearly. The LEDs also have a beautiful daylight colour balance whereas the HIDs give a warmer glow.
Note that all photos were taken with same camera settings in manual mode so that you can make a direct comparison.
Excellent job on the photos!
Thanks for doing that.
