They can be a little ditzy. One red light on usually means the jack is not all the way up into the retracted position. Some of them retract very slowly for some reason. I have a slow one that takes awhile. Sometimes, you can push it up by hand to help the springs. BTW...are your springs and plate in the correct position? Sometimes the plate can slip off and needs to be put back in place. On my rig, the red lights will come on while I'm going down the road. The fix has been to keep the "Store" switch "on" while underway. Also, check the condition of the surface of your jack plunger to see if it needs cleaning.
