Regarding clear lenses for the indicators - I got mine some years ago from SVC - here
http://www.s-v-c.co.uk/category/indicators/At the time they only had the front (more modern) ones, and this was well before they were available from Librands or Morgan. The MCC units are excellent value! For the rear indicators I sourced clear Lucas L691 from Ebay and bought the bulbs separately. The orange bulbs are a good colour and I have never had any problems at MOT time. You can get silver-coated orange bulbs that don't look orange when unlit, but they're not quite as bright. I also have clear side indicators (see another thread) which were made for me but I couldn't get suitable orange bulbs, so I used Tamiya clear orange paint (for modelmaking) on standard clear bulbs, which has stood the test of time.
I'd like to change all the lights to LED but would prefer a properly designed, chrome plastic reflector rather than just sticking a "LED bulb" in the pathetic standard Lucas lamp unit. It's the reflector design that makes an LED unit - they are so directional that with a poor reflector they give a very uneven pattern and particularly poor coverage at the sides. I think though that the wing-top "torpedo" lights could easily be fitted with a bright white LED for a very effective "day running" light.
