I was taxiing out in an MD80 one night and couldn't get the thrust below flight idle, also the strobe lights came on on the ground. Thinking it was an overserviced nosewheel strut causing the problems I used solid braking to bring the nosewheel strut lower and the problems went away. During their day operation they wouldn't have noticed the strobe lights but should have noticed the power was above normal. I assume the 82 is the same system as the 80.
