Ah yes. I gotcha. Im not a big fan of it personally. You can buy diffusing film/paper really cheap. Just cut to fit right under the overlay. 2 layers if you want. LEDs by nature are very directional/focused lights compared to an incandescent bulb, which is about the equivalent of a tiny fire burning, so although very hot compared to LED, the light goes in every direction. And our clusters were designed with incandescent bulbs. '03 was a little better by adding more to help even out the light better, but still by far a bare minimum amount of light in my opinion. And that's because if they had added more, heat woulda made short lives of our clusters. If only GM had foreseen the fact that LEDs are abundant nowadays and being used everywhere.
