Headlight Issues

[SHEEBANSAVAGE]

Hey guys,

 

I am having a problem with my headlights:::: This is whats happening....when I am driving along at a high RPM, my headlight go from bright to dim to bright to dim. I know that they go dimmer at idle because there is no engine rpm to give the necessary voltage, but this happens when I am at all ranges of RPM

 

Any ideas of the problem???
