EL lamps are a good option for backlighting membrane switches.  They are lower priced compared to fiber optics and offer additional design flexibility. Some common colors are blue/green and yellow/green, white, blue and orange. The life of an EL lamp varies based on the way it is used. EL lamps have a half life; once they reach their half life the brightness starts to fade rapidly. If the light is just being turned on when you hit a key on a switch the lamp will take a very long time to reach its half life of approximately 3000-8000 hours depending upon the quality of the phosphor being used.
