Marquee light is way too bright. Can I wire in a resistor to dim it?

How about something like a dimmer?

Yes you can.
They can get a little expensive though.
One guy I know bought special dimmers for his under cabinet led lighting and paid $80 per dimmer.

Here are some

You can use a fan speed control for a PC on the LED to dim it.   These only cost 4 or 5 dollars.

This could work.

One thing that bothers me is that, while the marquee colors match beautifully when the marquee light is off, the marquee colors get a bit orange and don't match the cab so well when the light is on.  Maybe I could find a brown, semi-transparent material to put behind the marquee graphics.  Any ideas what I could use?  I will try to find a hobby store around here this afternoon.

Many years ago I used something called onion skin paper for tracing images but it was 8 1/2" x 11" so it may be problematic.  The paper was semi-translucent and brown.  I'm not sure what the real name is but it was commonly used in drafting and circuit tracing about, oh, say, 35 years ago.  It's probably still around if you check at an art supply store.  I imagine this would be a great application however you would have to be very mindful of applying it or any other material in equal layers to maintain a uniform translucency.

Thank you.  This may be a good solution for me.
