On one of my posts I mentioned in passing putting a LED in back of the meter to backlight the meter so you could see it in low light situations.
Well today I went to rad shack and got a Brignt Red LED, a 2AAA batter holder and a trimmer/variable resistor. I had a switch in my junk box. I ran the positive to the swith to the trimmer to the LED. The negative was connected directly to the LED. I located the LED on top of the meter so it projects down and lights up the meter. IT WORKED!!!!
I now have a nice red, easy on the eyes meter for low light situations.
One TIP when you do this. Make note of the color of your needle. I forgot that my needle is also red. I should have gotten a White Bright LED. But what the heck. For an experiment it worked.
Perhaps you too can change your incandecent wheatie bulbs with Long Life Bright LEDs. |

Good on you DEADLY EYES,I plan doing just that on my meters and other equipment which do not have back lit illumination and other gear for when the wheaties blow out.I was caught out while on radio watch under RED light conditions trying to message take with a RED pencil.oh my!

I replaced the meter lamp in my Washington with a white LED. For anyone planning to do this, you will have to play with the bracket that holds the meter bulb in order to get it to light the meter evenly since the LEDs tend to project their beam straight out the front. Though once you get it it looks real good just as bright as the original. |

Try sanding the front of the LED to diffuse the light or maybe a dab of white paint on the tip of the LED? |
