Not sure these answers have helped the original poster, as 2003+ halogens also have same reduced amber for turn signals as litronics.
Litronics have a approx 2.5 inch round circle from which the main beam projects a very focused light. You can see this clearly when looking at the headlight, even if it is not on. Non-litronics look like regular headlights.
