LED lamp replacement for old Type 47 bayonet lamp?

Need advice,

I'm fixing up an old Hallicrafters Tube radio and I look to replace the original type 47 bayonet lamp with a long lasting LED lamp. Specs for a type 47 lamp are as follows:

Miniature Bayonet (BA9)
Circuit volts 6-9v
Rating volts 6.3v
Rating Amp 0.15a
Life 3,000
MCSD .52

I've found this link:


Where can I actually buy some of these is small quantities?

I am going to use the LED lamp for a dial faceplate and don't want extremely bright; as a matter of fact, I'm looking for a dim Red glow...
