Interesting I already have Koito headlamps so maybe previous owner changed it as it is a 90's model. Sealed or semis I wouldn't have a clue but they are very easy to change. Finally got her running properly and back from workshop, which during the time I changed the el cheapo fleabay try-hard "HID" colour H4s to Osram Nightbreakers so hoping that will be a big improvement along with better angling. If that's not enough I'll consider those Raybrigs...
