Thats strange because on my Interstates they are soildered in . The hole cluster had to be removed. Was a prety good job.
That is really strange! The bulbs should be pushed into a bulb holder (the bulbs are a bayonet style) and the holder is then a "push turn" that holds it in place.
Sounds like someone couldn't find the correct replacement bulb and did a little modifying.
