Rear view mirror/map light (to LED) replacement issue

It's the tapered ends of the 4410-x9 that prevents it from properly seating into the brass contacts. I suppose the contacts could be "shaped" to accommodate the new LED festoons, but it was my understanding the 4410-x9 were a direct fit. Frustrating........

PS: I can't tell very well from your picture, but it appears the stock unit has collar tab, (or rigid loop, whatever you prefer to call it) and your using a bullet style. You use the collar to draw in the two opposing tabs to make a good connection. Looks like you will need to order the correct unit for it to be secure in the holder.
