Today's LEDs are a different breed.

These are not the LEDs of years-gone-by. No longer do you need to put up with florescent harshness or the bluish-white of early LEDs to gain significant power-savings over conventional and halogen bulbs. Today's LED technology allows for 'warm' yellow lighting in high watt equivalency with minimal heat (MUCH safer than halogen) and minimal power draw. In fact, LED lights are so much more efficient that you could run every single light on board for 12 hours and still draw less energy than one halogen accidentally left a-lit.

You can pretty much replace every light (or bulb) on board with an LED alternative. The easiest of course is to simply replace the existing bulbs you have on board with an LED replacement bulb.
