Three Red Lights during Thunderstorm

I was playing xbox earlier today and it started to rain heavily outside, a thunderstorm started and the power went off in my house so my xbox turned off and then restarted, but then the power went off again about 30 seconds after I turned on the xbox and 3 red lights turned on around the power button (all of them except the top right corner one). However, about an hour later i turned on my xbox again and it worked fine, there are no problems with it.So what I'm asking is this: Did the power failure cause an internal problem in my xbox or did the 3 red lights simply turn on because there was a power failure?Three Red Lights during Thunderstorm
It's just because of the power outage, so you shouldn't have any problems from the storm.
