these are after market halogens of same wattage i.e. 55/60 watts, only the color tone is a bit different.
Stock halogen are like 2800K which is orage or yellow light, does not look good to me
these are 4100k, neither yellow nor white, in between, just the right color tone to suit the capability of my eyes.
u can see in the picture the reach of hi beam, goes till end of lane, almost a kilometer
