Swapping out lamps for LED's in guage cluster ?

[snookers]

A while ago, I read with interest a thread pertaining to swapping out the existing incandescent lamps in the gauges and indicator panel on a R1100RT. I even kept the web sight which was provided within that thread directing me to the seller of the LED's.

Problem is......the web sight sells a multitude of various led's and I am at a loss to what I should be aquiring. I cannot find the thread of yesteryear to direct me in the proper direction either. the reason I wish to persue the LED's is that many of the existing lamps are burnt out......and the work involved in getting to the guage cluster is ridiculous, so I would like to do this properly.....and only once....preferably.
Is there anyone out there who has done this swap or can remember this subject and direct me to the thread I am talking about?
Any assistance is greatly appreciated.
