here's some pics of my key when I did a 15,000 mcd white 3mm LED swap. with two 3v batteries. Worked great, but my key ALWAYS has had a problem with breaking apart and pieces flying everywhere, and one unlucky time when i was hanging out at ELON university, I was drunk as ashit and don't remember where I put that little metal piece after I dropped my keys. So, no after pics since my key's light is disabled but I used it as a friggin flashlight at night sometimes.
