Hey guys ,I'm a new member and need of some help. I own a '90 LS 400 and everytime i turn on the light switch, the reverse indicator on the dashboard lights up no matter where the gear shift is at. When i'm driving and i turn on my lights, the car will not go past 20-25 mph and feels like it's dragging. The car runs perfect as long as i do not turn on the light switch. Also, the reverse lights stop working. Could this be related? Thanks.
