I have the files for the transparencies that i can give out if wanted. All that would need to be fixed is the headlight symbol and make the hole in the middle a little smaller.

The el foil i bought off ebay from a hong kong seller (the smallest i found that could be used to make 4 of these overlays) and it came with a single inverter. The inverter was for 12v and it makes a slightly loud whine, so i ordered a few 9v inverters and some lm7809 voltage regulators to bring down the voltage from the car down to 9v to make the intensity and whine go down. The prices are pretty good to buy the el and inverter (around 16 shipped if i recall correctly), the transparency was $3 from kinkos, and the self-laminating sheets were $2.5 for a package of 3 (brand scotch).

The guy i bought the el from seemed very nice and shipping was within 4 days or so (even from hong kong).
