Making white lens red.

Quite right ...



Quite wrong. White LEDs have a coating that fluoresces at various points in the spectrum, giving the appearance of white. If you block all but the red parts with a filter, the red will still show through.

Then I'll go back to my first response.

Ha!

By a strange coincidence I was in a Motor Factor a few years ago and a 'yoof' came in for some little coloured bulbs to 'pimp his ride'. After he'd gone, the guy said that all they did was to dip clear bulbs in nail varnish and sell them for twice the price
