I have the same lights in my 1991. There was one ceiling light that did not provide what I need. I replaced it with a Trucklite 80250c LED. the width is ok, but it is longer & required removing some wood in the ceiling. I tried taking a picture to show the difference, but it did not work out. I would estimate it provides 3x the light

Not original, but effective
