I have now put Narva Arctic Blue bulbs in - and also replaced the park lights of which one was stuffed.
Next was replacing the flasher unit - what a B@#&H of a job, unless u have hands the size of a 5 year old's!!
Another day of learning the weird and wonderful ways of the Japanese Wiring System!!
To my surprise it had an AIR HORN!! in there for good measure although not connected properly and therfore not working - now removed!
