I'm looking to replace my C900 dash bulbs with LEDs but having trouble finding a match. These bulbs

look similar tothe smaller ones, but the base of the existing bulbs is squarer thanthe base in that picture appears to be. Will that fit? And what is the spec for the larger gauge-illumination bulbs? They're Philips W3W 12V 3W, but I can't seem to find any information for the base type. I've looked through Bentley but either I'm overlooking something or such fiddly details are beneath his notice.
Thanks!
