Triton Labs has created a Gameboy Advanced with an internal lighting system called the Afterburner. It looks exactly the same as a regular Gameboy Advanced with the exception of a new switch that turns the light on and off. A single kit is only $30.00 USD, so all of you GBA freaks go check it out. Press Read More for further info and pictures!! There is no comparison in our opinion. Other lights are mere gimmicks when compared to the vastly superior internal lighting solution we've put together. We have found no adverse effects whatsoever throughout our extensive testing. Visually, the system looks exactly the same from the outside with the exception of a new switch if you choose to install one. Link play, accessories, etc. all work as well (we haven't tried using a second light so we can't say what the result of that would be). Essentially the GBA thinks it is powering an external light; thus it should behave no differently than if a worm light or any other lighting accessory was attached. News Source: Trition Labs
