All dashboard lights are on

About 2 to 3 months ago I had my rear passenger taillight out, so I changed it simple. Had no issues w/it until last week! Last week just that 1 taillight I changed was staying lit even after car was shut off and parked! It'd stay on all through the night! I ended up needing a jump, so I took that bulb out. Everything was fine, same as usual afterwards. I charged the battery back up and haven't needed a jump or anything. This battery is almost 1 year old, so its still fairly new. Yesterday all of a sudden I got in truck, started it and every single icon light on dash is on. I don't have windshield wipers, hot and cold gauge not working, neither is speedometer. My son said it can be the battery may have come loose or is dying/not a good battery. Has anyone else had this issue, or experienced something similar? I can turn it off and start it up with out more problems! Haven't needed 2 jump or charge battery! I also have 1 headlight and that 1 taillight (obviously back not working because I removed it!) Its just very strange. I have heat and have lights on dashboard besides icons, radio works! What should I do? Or what can I do to rectify this problem, has anyone else experienced anything like this?
