I had the same problem I was using 42mm led white festoon bulbs reordered 44mm wire loop white leds removed the caps from the ends of the stock bulbs put them on the new wire loop led bulbs wire runs through it and it works right..
Also used one of the wire loop bulbs in the trunk without any caps (that one dont need caps)
Now if I can just solve the rear seat is not really a bulb problem I d be ok. Yes the back of my seats is what I m talking about
