Cleaning the headlights
 

I've been meaning to do this for ages and the before and after pictures below show that it was worth the effort.

I used a Holts kit; https://www.amazon.co.uk/Holts-11750.../dp/B075KFP3H5

Plus, and this makes it much, much easier and less likely to scratch the headlight lens, this pad between the drill attachment and the wet and dry discs: https://www.ebay.co.uk/itm/293224647248

And I ordered more wet and dry discs as there weren't enough in the Holts kit: https://www.ebay.co.uk/itm/285825781902

Reading this prompted me to do what I promised last October (here: https://forum.a8parts.co.uk/showthread.php?t=17118 ) and go back to improve mine.
A few more minutes work on the errant (nearside) headlight resulted in further improvement, almost back to normal. Brasso and Silvo again.
I just opened the bonnet, unscrewed the trim strip below the headlight and swung it aside and worked on the headlight section, the indicator isn't too bad.
