Thanks to everyone for their help on Part I (electrics).
I am now trying to source some thin (5 - 10mm) tubing that I can use to hold the bulbs, and to take the wire. Microbore copper tubing would be ideal but I don't want copper. Ideally I would like stainless steel.
Any ideas where I might find this, or similar? I guess it might be used in pneumatics or high pressure systems? Who else might sell such tubing?
Thanks again. Paul
