I would advise against getting the bulbs on ebay, simply because you have no idea what kind of LED's you're buying. You want to know what the lumen capacity is and a rough idea of the power draw, otherwise I'd stay away from them. Also, get colored lenses, not just white. The lenses are there to filter out the rest of the spectrum except for the color you want to see, if you get the same colored bulb right off the bat you will have a brighter light. Also, if you went for clear lenses later on you don't have to re-buy the bulbs.
