<br></div>The key word you are looking for is PWM. This is Pulse Width Modulation that basically just turns the LED's on and off very fast. The amount of time they stay on determines how bright they appear. <br></div>One note of caution. Read the instructions that come with a PWM dimmer carefully. Some require that the LED's connected to them are NOT grounded. This can be a real pain the butt for LBC's where everything is metal and all the metal is grounded. If possible try to get the specs for the dimmer before you buy and make sure it is referenced to the input ground. It can be a lot of work to float all the grounds on your dash wiring. Another issue to consider is that the PWM modulation can introduce noise into your electrical system. Most PWM dimmers operate in the 100Hz frequency range. This is noticeable on your radio if it is older or not well installed. It can also cause issues with electronic ignition modules if they are not well shielded.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Feb 20, 2018 at 11:58 AM, David Soknacki <span dir="ltr"><<a href="mailto:soknacki@soknacki.com" target="_blank">soknacki@soknacki.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><u></u>
