Cubby Posted September 30, 2004 Share Posted September 30, 2004 I have an illuminated rocker switch I use for a pair of driving lights (Radio Shack PN 275-731). The red LED light on it is too bright. How can I dim the light on it. I am not an electronics guy but I assume I can install some type of resistor on the negative connection? I do have a non-illuminated switch I could use but I light having an indicator on the dash that the lights are on. Thanks in advance. Link to comment Share on other sites More sharing options...
denisb Posted September 30, 2004 Share Posted September 30, 2004 An LED is going to be harder to dim. Unfortuatelly an LED doesn't have as wide a range of brightness as a light. I tried it just for $h!ts and giggles with a 1 kohm (1000 ohm) resistor. It dims a bit. Might be enough to help you. Just install it in series and try it. Just so we're clear to connect the resistor in series, disconect the wire going to your light on your switch, solder one side of the resistor to your switch prong and the other side to your wire or connector you just dissconnected. Hope this helps and good luck! Link to comment Share on other sites More sharing options...
Cubby Posted September 30, 2004 Author Share Posted September 30, 2004 Thanks Denisb. I will try that. I was not sure of what size resistor I needed or if there are specific 12 volt resistors. Link to comment Share on other sites More sharing options...
88pathoffroad Posted September 30, 2004 Share Posted September 30, 2004 Take a Sharpie and put a spot of ink on the light first. Try that. Link to comment Share on other sites More sharing options...
Cubby Posted September 30, 2004 Author Share Posted September 30, 2004 I tried painting it with black car touch up paint but it didn't really make a difference. I need a paint that will stick to the glass. Link to comment Share on other sites More sharing options...
denisb Posted September 30, 2004 Share Posted September 30, 2004 If you don't want the light at all.........electrical tape. Oh and by the way, if you get a resistor, just a regular 1/4 watt 1 kohm resistor will do. Link to comment Share on other sites More sharing options...
Mark Posted October 5, 2004 Share Posted October 5, 2004 A little strip of 'smoked-look' contact paper ought to do the trick. Or nail-polish. (Don't ask me how I know this). Link to comment Share on other sites More sharing options...
