89 euro issues.....strange electrical phenomena

i am a very happy owner of a euro spec 520i. just one issue.....my led oil service lights located inside the cluster (the red and the yellow not the three green) stay illuminated when i turn the car off and lock it. i think it may have been part of an aftermarket alarm system or maybe my cluster is bad. doesnt drain the battery and i have no öther issues besides. any thoughts??? also i have tried to reset the service light using a tool and this has no affect on the lights??? i am a new member and would be thankful for some help.
