Bicycle lights

a) Isn't it frustrating to have to pay a fine of 400-900 kr for not using bicycle lights?
b) Isn't it annoying when people steal or brake your bicycle lights? Therefore you should carry them with you when you leave the bike but:
c) isn't that also annoying?

One solution:
This is a normal old style bicycle light that is less likely to be stolen because it's mounted with a nut and less likely to be broken by drunk by-passers since it looks old and "broken".

As you may notice, this light has a switch on the side. That switch goes to a battery pack (2xAA), a suitable resistance and a white LED (a Light Emitting Diode, en vanlig diod) in series. Voila! You have a light that you a) don't get fined for, b) wont get stolen or broken and c) don't have to carry around!

Ask me for help if you want to build one :)
