i bought these over a year ago now, still working fine. http://www.ebay.co.uk/itm/10x-NO-ER...arts_Vehicles_CarParts_SM&hash=item1c25dbcd16 10 is enough to replace all interior lights including boot, and number plate, hope this helps
Far as i remember at the time reading on the forums the canbus ones were required or you get error messages on the dash. They have a resistor on them to stop the errors AFAIK.
