Quick fix for headlight lens 'bloom'.

Our 2004 Citroen C5 recently sailed through its MOT with a single advisory, noting that the Polycarbonate headlight covers had an external ‘bloom’ reducing light emission. Having spent many years in the plastics industry, my single and careful application of ‘Brasso’ removed most of the problem. Maybe owners of other modern cars that have similar moulded covers may find this tip worthwhile.
