You are entirely correct that most LED's are pretty much unidirectional - i.e. they radiate in a front facing cone of light. As an electronics engineer (now retired) I rather rapidly slip into the design mode and think about how I would make a solution. We need a structure to hold an LED (or maybe 2 or three **) so they shine down into the dial area. Then we need a small number of extra parts to drive the LED's (which need DC) from the existing bulb source (essentially 12 VAC). Then we need a way to connect our new little LED assembly electrically to the old bulb. All very doable but they will require a bit of thought to pull it off. I don't own any Heathkit gear at the moment although I certainly have some other older radios that could benefit from an LED approach. </span></div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr"><span>Good luck - let us know what you find out.</span></div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr">** Two LED's might be a nice choice as you could put one across the other in reverse polarity arrangement. Then one acts as a reverse protection diode for the other. Also means a single dropping resistor. So 2 LED's and one resistor.</div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr">73</div><div id="yui_3_16_0_ym19_1_1483461543122_15084" dir="ltr">Bob Groh, WA2CKY</div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue-Light, Helvetica Neue Light, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Tuesday, January 3, 2017 8:40 AM, Joseph Smalley via Heath <heath@puck.nether.net> wrote:<br></font></div> <br><br> <div class="y_msg_container"><div id="yiv1677980801"><div><div style="color:#000;background-color:#fff;font-family:Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:13px;"><div id="yiv1677980801yui_3_16_0_ym19_1_1483411248338_3263">I have posted this question once before about replacing the dial lights with LEDS got a few suggestions.</div><div id="yiv1677980801yui_3_16_0_ym19_1_1483411248338_3352"><br></div><div id="yiv1677980801yui_3_16_0_ym19_1_1483411248338_3449">One was using LEDS from the Superbrightleds company.
