Parking brake less than 50% (mark as a dangerous defect)

Headlamp not working on dipped beam (major defect)
side repeater not working both sides (major defect)
shock absorbers has an excessively worn bush offside front (top mount) (major defect)

oil leak, but not excessive (monitor and repair if necessary (advisory))
tyre slightly damage/cracking or perishing (both rear badly perished) (monitor and repair if necessary (advisory))
suspension component mounting prescribed area is corroded but not considered excessive (both rear inner sills) (monitor and repair if necessary (advisory))

First one will be easy to do, that just means tightening up hand brake cables
Second should be easy to do, The two lights side light and dip headlight might be a fuse or just bad connection.
Third going to present a problem, think they are on about top of the strut this will not be easy to replace
