Toning down Savage Switch Lights
RazMan - 23/6/07 at 12:03 PM

I am sure this has been discussed before but I can't seem to find it.

My Savage Switches are far too bright for night time use so I need to put a resistor in series with the feed to the leds. I've got six altogether so what value resistor is a good starting point?

Is THIS the thread you are looking for?

Oddly enough, started by yourself

Ahhh that's where it went

I think that thread got a little out of control and I eventually decided to keep things really simple and forget about all the electronics.

I have my switches wired so they simply come on at night (in parrallel with the side lights) so I just need to dim them down a little.

A variable pot would probably be a good starting point - but what value?

measure the resistance of the light connections of the switch (i think there should be some kind of resistance there) multiply by the number of switches (if they are wired in series) and a resistor of the same value with half the brightness.

unlikely they're in series though, so if they are... i forget how it works sorry

you need to mesure the current the lights in the switches is currently pulling, or look in the specs for a figure. Once you know this you can start to think about what size resistor you need.
