INTERIOR LED's

eBay or Amazon ones are just as good as the ones at halfords etc - they're all made in china.

Try to go for ones with a warranty because about 20% will fail within a few months. The 5 led plastic ones are notorious for being poorly made, the canbus and aluminium ones tend to fair better. Bulbs marked with the popular LED brand 'Cree' may not actually be made by Cree, but will instead include Cree LEDs.

If you're interested give me a PM, I've actually got a variety for sale.
 
I've got the white plastic square LEDs in mine. Sorry if that sounds daft. Interior is pretty bright. Think Steve put them in when he owned the car
