and... a LED requires some form of current limiter (e.g. a resistor) as it's not a 'resistive' device like a light bulb (which is really a light-weight resistor in a vacuum). If you wire a LED between v+ and eath, you make a short and the LED has extremely short life, a resistor between the LED and v+ will prevent this. LEDs are also a diode, current has to come from correct direction to flow thru and light up.
jaycar are selling some light-bulb replacement things using LEDs - probably a bit pricey if you can make small PCBs but for the non-geeky, non-soldering-iron-savvy they might be what you're after - tho for the mini lights in your dashboard, you might have to make it all yourself.
there are some super-bright LEDs on jaycar's web site <www.jaycar.com.au>
