Possible electrical issue???

About 2 weeks ago my Jeep wouldn't start after work and I just tapped the battery terminals in case it was just a bad connection and it started right up. But, after that my Jeep's dash and radio lights have been dimming in and out while I'm driving down the road for no reason. My radio will even go off and on periodically. It starts just fine now and I had my alternator tested and they said it was good, but it seemed like it was working harder than it should be at idle so it may be on the verge of going bad. Everything electrical is stock including the radio. I will probably go ahead and change the alternator, but any other ideas or help would be greatly appreciated!
Thanks
