It's nice to finally be able to read the gauges at night... one thing I find really odd is the glow in the bulbs when the battery is disconnected. I hope it's the capacitor in the distributor, not the car slowly disoving and generating its own electricity...
We had a household LED bulb that used to do that. I read that it can be caused by poor quality bulbs and a switch that lets through a tiny amount of when off, or an earth wire with very high resistance or not making a good connection. Another reported reason- and this takes some believing - electromagnetic induction allows one cable running alongside another to pick up sufficient juice to just let the lamp glow. The latter cause is, I suppose, just like laying an induction loop alongside the live rail of the electric train line at the bottom of your garden and getting a free supply to your garden shed.
That's all very well, but when the battery is disconnected, the source of electricity is my greatest concern!
...and if you want induced current, your probably best trying an AC source. I'd stay away from the rails if the 750v DC third rail induced current into its neighbours.
