LED are still yet to be as good as HID but are rapidly getting better.
Interestingly on my recently sold Perentie 48-852, the lamps were a dim yellow orange. I swapped them with a pair of reflector units from a civilian 110, with the headlamp buckets and wiring tail off the same 110 and ran a new ground wire back to the firewall on both sides (picking up the original ground post behind the outer mudguard in the process). The change in the brightness and colour was significant.
