Someone asked about that last week, I can't find that thread. I just changed mine. You can twist the socket counter-clockwise and pull backward. The passenger's side is easy as you can use your right hand. While in the driver's side, your hand may not fit because of the battery, so move the battery and use a long nose plier to pull out the bulb.donnie15 said:last question about lighting and my t4r's lighting is done. what is the bulb that is circled below? how do i get to it to replace it?
