Most lighting projects can be accomplished with field approvals or, rarely, an STC. Your cabin completion center can likely answer any concerns you may have about lighting projects, but to be sure, FAR Part 25.812 spells out what's required for emergency lighting, while the SAE's Aircraft Cabin Illumination Standards cover the general recommendations for cabin lighting in order to provide satisfactory illumination for.

Development of LEDs began more than a century ago, but the first practical versions were produced in General Electric labs in the 1960s. Until 1968, visible and infrared LEDs cost on the order of $200 per unit, and thus had little practical use. In 1968, Monsanto mass-produced visible red LEDs suitable for indicators. Hewlett-Packard advanced the concept for uses in alphanumeric displays, which were integrated into HP's early handheld calculators.
Duncan Aviation has developed an iPad-compatible wireless interface for cabin management systems. The iCabin application connects an iPad to an aircraft's CMS, providing passengers with a remote for sound, video and cabin lighting on aircraft equipped with Wi-Fi capability. The fully customized iPad application doesn't interfere with other onboard systems or change functionality, says Duncan. It also may be used to control most audio and video equipment. A wireless cabin control application for Android devices is also being tested.
