Hi, I recently changed my headlight with a H6024 from GE. The light pattern is sliightly different, but, its much brighter than the original Stanley light bulb. The main difference in design is the internal filiment is smaller and weaker in a auto headlight when compared to a M/C light, therefore may burn out sooner. Many posts on this site lists folks with this same bulb for over 3 yrs without problems. Hope this helps. Dr Mark
