So I saw Freddie's post and the JDM accessories catalogue for their Galant Fortis:

I was keen to get this done.
Unlike Bro Freddie and the Japs, I used a neon tube as opposed to LEDs.
My neon tube was bought from a local company [url="http://www.aerpro.com.au/list.php?pcode=NE24B&cat_name=mobile%20lighting&cat_no=01&cat_sno="]Aerpro. 24" long[/url], water resistant and costing A$18/- after 20% discount.
And unlike Bro Freddie and the Japs, I wanted 2 ways for the nose background light to come on:
a) When the door of the car opened, so triggered by dome light circuit; &
b) An override switch next to the ASC switch, so I could turn it on when I wanted e.g. chasing down someone in the night
So I had to design an auto electronic circuit for this. Using 2 x 4 pin relays (A$10.00) , a 3m length of wire (F.O.C. take from Science Labs) to tap my battery and for jumper wire, I pulled them into the car cabin through the hole in the driver wheel arch.
I also had to tap my dome light circuitry which I found behind the panel where your front bonnet opening lever is to act as the trigger for the neon. You will also need a diode (1N4002 about A$0.25) and a capacitor (~50uF about A$0.25) to do this.
I used a 34.5x20mm switch (A$2.50) which fits perfectly in place of the dummy swith next to the ASC button as the override and a couple of 10A in line fuses (A$4.00) to complete the circuit.
I also used 8 cable ties (A$2.00), some 3M industrial double sided tape (bought for other projects), both to attach my neons behind the license plate so the glow directed towards the radiator and some plastic wiring shell to protect the exposed wiring in the engine bay (10m for A$2.50).
Here is my pin out guide for the relay assembly. (Sorry too lazy to draw it out but if you need me to send PM)
Relay 1 (To Neon):
Pin 30 = 12V Batt through 10A fuse (Line1)
Pin 85 = Grounded to body
Pin 86 = from both Pin87 Relay2 & Acc from switch
Pin 87 = to neon
Relay 2 (from dome light circuit):
Pin 30 = 12V from Batt through 10A fuse (Line2)
Pin 85 = to (gnd) of dome light circuit
Pin 86 = to (+) of dome light circuit
Pin 87 = to Pin 86 Relay1
also solder the capacitor between Pin85 & 86 to prevent chattering of the relay as the dome light circuit dims down
Switch (LED on switch best so you can see if it is on)
Power =12V from Batt through 10A fuse (Line2)
Acc = to Pin 86 Relay1 through diode
Ground = Body of car
Lots of protection from the fuses and the fact that a cascaded relay arrangement will protect the wiring I set up and the car's own.
Here's an image of my override switch:

and during operation (driver door open so dome light circuit triggers neon):

So total damage < A$50/- !! Way cheaper than the Japanese quotes of Y28,350 (~ A$404.75)
