I wanted to jot this down before i go to sleep this morn. I I hab a slight idea but dont kno. On headlights with seperate high and low beam bulbs. I was asked and was confused caus ei did not know either. On the low beam bulb in the headlight there is , on all i seen, sum kind of capsule that covers the tip or front portion of the buld. Wut is that there for anyway? The high beam sides never has this , so why does the low beam have it. Is it there to help reflect the light?
