I pulled the bulb out of mine because it annoyed me severly. I don't need to be told when to shift. If anything, you can get complacent with lights going off on your dash all the time, that you may just accidentally ignore the CEL when it goes off. I know most of us would notice that one, but I am trying to make a point. If you don't know how to drive standard properly, buy an automatic. That light is intended for fuel economy, and yes, it does a poor job even at that. The only people who need a shift-light are drag-racers with manual trannys, and if you are a dragger, you definitely don't want what Ford is cooking with that joke of a shift-light. Pull the bulb and get an aftermarket tach with a shift-light in it... one that you can set to your preference!
