Just replacing halogen lamps with new ones will often give quite an
improvement as they seem to age. The high efficiency ones can be better
too - but likely have a shorter life.
HID conversion kits can work very well and not dazzle - but this depends
on your reflector design. The projector type that use a separate flag for
cut-off usually work well. Those where it is part of bulb, usually not.
