It is difficult when you cannot see the controls at night to select the right vent setting with no light or in a scenario with a bulb which is slowly but surely getting ready to die is a sticky situation.

Pretty basic household tools required to change this part. If you do not have small needle-nose pliers then tweezers will work, as well. With your tweezers or needlenose pliers very gently hold the new bulb and work it back into the socket. Make sure the wedge part of the bulb is vertical. Once it is slightly in, you can use your pinky to fully push it back into position. You can also try putting the bulb back in with the air tube (though that method never works for me).
