Extending view of the LED display

I just got a PA-II Flex (yay!) and installed it. I’d like to be able to see the color of the LED from a wide range, but it’s only obvious from below and to the right of the sensor. (It might be more visible at night.)

I was just wondering if anyone has had any success attached something below the sensor to help see the color of the LED. Either a mirrored surface or maybe some kind of translucent white plastic. (It would help if the sensor’s wall was thinner or more translucent where the LED is.)

And yes, I have the LED power at 100%!
