Both my 68 Bird and now my 67 LeMans have the "capsule" light for the lighter. If your car has two "capsules" the second I beleive would be to light the ring around the ignition as the ashtrays do not use a "capsule" they use the fiber optic line that draws it's light from the back of the gauge cluster. Your car may no longer have the correct bezel around the ignition switch for that second "capsule"...
