It really is a 5 Minuit job ,but it took me 4 hours and 5 Min's, I changed the main beam by mistake and that took 4 hours Duh!!!!. There is a lot less space to work in due to the rad tank, working with a mirror and looking thou the wrong part of my tri-locals proved to be rather challenging. After an hour I managed to release the clip then working from feel only I tried to remove the bulb, however it dropped into the head lite housing along with the clip, so another hour was spent trying to retrieve the bulb and clip.
Using fishing line ,string and a mirror I somehow managed to replace the retaining clip, only to find I had put in in back wards , so I have to switch it to the correct position. Not wanting to drop the bulb into the housing I used fishing line and threaded it Thu the bass terminals this part went fairly smooth, a bit of a struggle to replace the clip and time to test, "OH NO"
Replacing the low beam is a piece of cake,
I tried to remove the rad overflow tank, but there must be a hidden bolt on the underside of the tank,I also tried to remove the headlight assembly but again could only find 2 screws.
