I have the red card, but also had to add a red bulb. I found the clear too bright, I also painted the hood inside with black to stop the light shining through. It may be that I am more sensitive to light than most, it can come in handy, I rarely need a torch, but on the other hand I am easily distracted by stray lights at night. I have to turn most instruments off when not in use.
Sorry, just an aside.
I must admit though, I am pleasantly surprised with the compass as a whole, nicely balanced, easy to read and clear. Keep meaning to buy a few spare covers though, I can feel ours starting to wear and not snap into place as it should when new, this will be the 3rd season.
