 Head Up Display
 
Difficulty - **
This is a Renault Megane, ready for the HUD.  
Get your ass onto www.google.com and image search for large image of a set of lit up speedometer clocks / rev counters.

So look for:
- Speedo Night
- Clocks Night
- Dash Night...... Etc Etc..

Copy it off the Internet Explorer, and paste it on the car image
 
Hit Ctrl+T and use the grab handles to flip it, and then skew and change the shape of it to fit in with the windscreen...  

OK.. head for the layers box.. Ok, go down the list and pick the layer setting; Screen.  
It should look a bit like this. Looks good on darker window screens and night time scenes.  
As seen on my Opel Astra..
