      I have fitted a combine with a couple of strips of 12v  AMBER flexileds (3 leds per strip)  (the 3030 types as I find the 5050 types too bright.

       I connected them to a Lith 400 MAH PP3 via switch.  Works ok on 9v and I am not bothered about reharging  times spacing...

      Battery charged  via its own self contained socket from a Lappy via min/usb cable available for these batteries.

      Does for me.

      don't know what happened to the description on this but again: placed 2 AAA battery holder along with small slide switch purchased at RC hobby shop in clearstory of roof, 10mm x soft white LED's were installed on styrene rectangle tube and were powered by copper foil used to make stained glass windows with to limit wiring hanging down. Left one on by mistake and found it a week later still lit. If 1 wanted a more yellow light I have covered it with yellow from a highlighter. light on

      I did get magnets and batteries and the tests have proven successful. However, when a mechanical engineer messes with electronics, generally some big chunk of metal ends up in the circuit. I really like the 'wave a magnetic wand' method of switching the passenger car lights on and off, and since latching reed switches are mostly unavailable, I came up with this genius solution. This is part of the battery box inside the roof so I can use a magnet outside the roof to move the ball bearing between the wired and unwired boxes. Mechanically it works a treat but electrically, when shaken around as if travelling on my branch line level of track maintenance, it reintroduces the dreaded blinkys. I even applied dielectric grease to damp the oscillations - no luck. 

      Back to square one. I want the battery box, wiring and lights all self contained for easy removal for battery charging so an external magnetic off-on capability would be a plus. Has anyone been able to find a source for reasonably priced and readily available latching reed switches lately?

      I did find THESE but no retail source. Anyone?

      Dave Bodner demonstrated such a set up at out club once. I would see if he knows.

      David - I once sold such latching reed switches on eBay - I had a good source but it has since dried up - I still have 50 or 60 left- how many do you need?

      There are some notes and a short video here
