NOOOO!!!! The lamp on my L&M ARC HID isn't working! The green light indicator in the back comes on, but the lamp doesn't light.

Traffic cooperated by leaving enough holes to slide through so I could leave them in my dust. But my light's not working!!!
edit: False alarm. Light's working. I charged the battery and it fired right up. I thought the battery was still charged, but I guess I was wrong.
