I just about a week ago finished my light upgrade project on the 1200 GX. It took up quite allot of time and I only had night time to do the conversion.

1. Get yourself some semi sealed beams that looks similar than the 1200 lights. They are 7" in size.
2. Get some 25A silicone wires and two relays 30A each.
3. Connect everything up. I replaced the stock wiring of the existing connection with the thicker silicone wire and used the two original wires coming from the cabin as triggers for the relays.
4. Buy yourself some Philips H4 Vision Plus bulbs. they are rated 55/60W.
Install and enjoy. It is a HUGE difference. White bright light.
My 2004 Nissan Pulsar's lights doesn't come close to these lights now.

this sounds like a good project as i have no auto electrical experience at all

No problem ZigZag. It is not difficult. The most difficult part for me was to organize the wire to look original again and to tape it up again to look neat and as mentioned, original again. I also don't have much auto electrical wire experience but I managed.

Here is a link to a picture showing how everything must be connected.
