They also have a conversion so that when you switch the ignition on only the sidelights come on until you flick the main beam on and then the lights will work normally until you switch the ignition off. This ensures you get the battery power available for starting the engine. I found that when I used this conversion I only needed the one extra relay as when I used 2 the lights would not switch off at all.
The lights should go off when you press the starter (at least my 04 does) as there's a relay to do precisely this. This, and what you say about the lights switching off, probably indicates that you had the wrong relays fitted.
There are 2 pin layouts (I've posted about this in a thread here years ago). One works correctly, the other seems to but in fact gives a constant current drain.
