I know we all love threads on white sidelights, so I thought I'd start another
I had some LED sidelights and whilst they were ok I wasn't fully satisfied with them.
So I bought some Extreme White Xenon Sidelights from this site

The light they give is better than the LED's and more what I was after

The problem with them was that when they were off they looked very blue through the lens.......
.......
not any more they don't
Removed the bulbs again this aft, cleaned them thoroughly and inserted them into a piece of polystyrene
Then found an old cardboard box and placed the whole lot inside.
Next comes the good bit
Take one small can of silver spray paint and aim carefully at the bulbs, the spray lightly, turn polystyrene round and spray the other side
Leave to dry for a few hours then replace in bulb holders and test
They only need a light spray, not covering solidly with lots of coats.
