Please help!! 2005 Acura TL auto trans. My front corner lights, front and back side markers, and tail lights not turning off. The indicator on the stick left of steering wheel is turned all the way back to the off position. Lights even stay on when key removed. I have never had this happen before with any vehicle. Anybody that has any suggestions would be great. I don't even know where to start. Thank you.

Never had such issue. However, from electrical point of view, sounds like faulty relay.

 

"Tail light relay" is build-in into the fusebox - meaning you can't easily replace it.





There is a possibility that something else is back-feeding the circuit or that for some reason relay is commanded ON all the time.
Figuring that out would require some checking. Multimeter and test light required. Probably also disassembling the fuse box, at least to the point that allow for probing the I6 white wire.

For now you can take under-hood fuse #4 out and that should turn the lights OFF. Just put that fuse back if you need to drive somewhere.

 

It could also just be the indicator switch that's malfunctioning, I've seen it happen before.
