Have to say I'm delighted with the way it looks now. Big improvement. Even the missus noticed the difference and believe me that is saying something!
The credit goes to the guinea pigs who went first though! rjkflyer in particular. Cheers

Your resistor values do indeed work with regards fooling the lamp failure monitor and theres not too much heat at all. You can easily keep your finger on them so no danger of melting anything! Also glued the resistors to the covers.
Its the same type of bulb from the drls that goes in the rear cluster for indicators etc. Tried it very quickly as it was getting dark tonight. Looks pretty cool but not so easy to do the resistors. Gonna take the lining away from the boot tomorrow to see if there's enough space. Very difficult to show the effect properly but the LED binary on-off rather than dimming and lighting as per the filaments looks much better (just like my old m3!). LED lamp is in the cluster on the right shown below.
And, before anyone asks, yes it is the same car! just the front is nice and clean for the first pics!!
Just for reference, also a pic of the front in the twilight.
