Thanks, Steve, I just ordered a lamp, along with other items, from mouser.com, just about the same price, mouser doesn't have as big a selection, but the lamp I ordered is a 5v lamp. From what I have read, the lamp is run at low voltage, and when engaged, runs higher to give the "on" look. I measured the rails and it's 5v, so a 5v may not be the right value...
