RS's prices are pretty high for commodity LED's. You might just want to
get the assortment of 20 for $2.59. Most of them are going to be red,
anyway:
276-1622
You don't need the 12 volt model--it has an internal current-limiting
resistor; the forward voltage on most of these isn't going to get much
higher than about 2V at 20 ma.
The following should work just fine:
276-026
276-041
Cheers,
