The prisms just reflect the light around the cluster. Bigger prisms, bigger reflection?
Also, it's important to note that on the older instrument clusters the speedometer is mechanically gauged. You may run into a problem when getting the newer cluster to work in the older cars as the New clusters are Electronically gauged, the are not compatible. Not sure what year this change occurred, venturing to say '90. Check the back of an older cluster and a newer cluster.
Older=screw on Newer=plug in.
May be wrong on that but, it's what killed my upgrade when I tried putting in a '94 cluster in my '86.
