Ok Halfrauds, 501 bulbs replaced all overhead LEDs and the two footwell LEDs. about £7 for 6 bulbs.
No more disco, corsa, rice boy...car back to stock

Done.
The footwells pop out of their position and are encased in a light metal shell, you just gently prise this off to access the bulbs.
I can relax in the knowledge that I won't be bathed in blue light.
If anyone on here wants 5 Blue LEDs free of charge, PM me your address details and I will pop them in a jiffy bag and put them in the post.
