LED vs Halogen vs HID in Headlights with Reflectors

[dr. d]

i stand and squat some distance in front and a little to the side of the vehicle at night, mimic-ing oncoming traffic, and see if the glare is acceptable. i adjust accordingly, if possible.

LED is brighter than filamented bulbs.
uncontrolled glare that may be tolerable using filamented bulbs, can become uncomfortable when using LED, using the same reflector.
