Remove the outer contacts marked with the red arrow by wiggling them back and fourth until they break. Carefully bend the inner contacts marked with a green arrow to the outer position (where the outer contacts were). Inner contacts are 5.4 watts, the outer contacts are 25 watts like the 7440.... way too bright. I have not been able to find a 5-10 watt 16mm base wedge bulb so i adapted a 7443. It's possible that there are lower wattage LED's that would work.
