Im slightly confused over what LED's to use in the various versions of Half Canbus / Full Canbus steering wheel controls.
I use 0603 smd's for the Facelift controls and they work really well. Changed them quite a few times now.
Also Lee_GSI's excellent LED how to specs up 0805 smd's for the scroll type steering wheel controls.
Are the preface and facelift scroll wheel controls different in some way.
What spec of LED are used for the Half Can Button type controls.
