These days non-standard bulbs such as coated bulbs with white-blue color, high power consumed bulbs and HID(High intensity discharge) bulbs were widely sold in the market. Non-standard bulbs are short of standard of automotive bulbs and can be caused glare to oncoming drivers and pedestrians. In this study, three kinds(100/90W, 130/125W, HID)of non-standard bulbs were used in this experiment. Photometric characteristics of non-standard bulbs are investigated using photometric measuring equipment. In addition, fuel consumption rate was predicted from experimental data of reference. Temperature of the inside of headlamp was measured using thermometer. The experimental results were compared with those of standard halogen bulb(60/55W). Consequently, photometric performances of non-standard bulbs were much inferior to standard halogen bulbs.
