See LED discussion for part numbers at http://www.pearsonariel.org/discussi...igation-Lights - it is a couple pages, but good reading.

(As has been discussed here previously by Bill, et al. ... and with all due respect to the website's functionality.... searching google with "site: pearsonariel.org LED" or whatever you are looking for after pearsonariel.org (e.g. site: pearsonariel.org peanut butter) is a much more fruitful search option than using the search option here.)
