I am fitting three illuminated push-button switches to my dash, and I can put a little icon in each one of them - I'll print it on transparent inkjet printable plastic and then insert it behind the lens on the switch.
So I need some black line drawings that fit into 10mm x 10mm squares and intuitively mean:
Front Spotlights
Roof-Mounted Spotlights
Rear Spotlight
300dpi is nice even though the printer probably won't really achieve that.
By the way these are sexy switches that I got from Dick Smith:

The red ones are $12.48, the otherwise identical green and blue ones are $4.93, and when I went to buy two blue ones the chick charged me $2.48, so I grabbed a couple more

Anyway, I can probably do something myself but I know there are people better than me at this stuff, thought someone might be moved to assist me.
