I have it and it's fantastic. Straightforward to fit but only with an electric fan mounted in front of the rad. Yes, Alasdair can be a little slow to respond to emails. I seem to recall he has somebody who helps him manage the Facebook Messenger channel so try that as well.

Yes. They work fine but you'll need a dimmer as they are very bright. I made one per Bob's design above and it works a treat. BTW I don't know what market had green dash lights. Both my large dials have blue diffusers. Not that they did much; the original lights were always a dim yellowish glow!
