They sell "HID" conversion kits that use 30W per bulb. I know several people who have used them with good results. Its all asethics to them to get the "white" light or "blue" light look. But these directly plug and play with any common size bulb 9004, 9005, 9006, etc, and H1, H4, etc. Look around and see what they have for your Corsa.
