Absolutely blinding LEDs in amp footswitch... what can I do?

    I have a little Mesa amp that came with a "Switch Doctor" footswitch. Three switches and three LEDs that are retina-searing bright when compared to the LEDs on my pedals. I don't absolutely need the footswitch but it's handy and I'd rather keep it. Any way to reduce the brightness of the LEDs? I was musing first about just putting some artful beige masking tape over them, then started thinking about whether a simple internal mod might tone them down.

    I use tape but I did recently see an advert for a cover to deal with this very situation. But tape works just fine

    When I need to pull down the brightness in a pedal that I have built, I use a larger resistor. Should work here.

    I had BBE box with a blinding LED. I put a piece of a label sticker over it. It was still very bright. I gave that thing to my daughter's boyfriend.

    Disconnect the wire from one leg of the led and solder in a 5k resistor?

    A square of blue painter's tape. The light on this one is white and so friggin' bright that I'm pretty sure it gave me retinal damage once.

    Your pedal's so bright
    You gotta wear shades!

    Blue Painter's tape works great... I've got a Cara Claptone with a bulb slightly brighter than the sun....

    I have one of those glowing lights in my Mini Super Beetle. I will continue following this thread. The tape would work but I prefer something that would look better. My skill adding a resistor not so good.

    The efficiency of LEDs is very high these days. Back in the day, you designed for 15mA or so to get them bright enough. Now, some of them are way too bright at 2mA.
    Short answer: silver Sharpie

    there ya go. if you can get to it, adding a resistor inline (either side) will do the trick. 2.2K is kinda the "normal" value I've seen listed. Mark's suggestion of 5K is a great place to start. I've used up to 50K for a softer classic look. tubescreamers must use something ridiculous like 500K to get that dim?

    but for way less hassle, masking it off and hitting it with a thin coat of spray paint or even scuffing it up with steel wool will diffuse the light and make it less obnoxious.

    who do we blame for the blinding light craze? first time i saw it was a late 90s Keeley mod...

    Chuckle....I hear you David.
    It seems you got all he necessary answers.

    BTW...I can relate all to well.
    I have the Behringer 1622FX mixer (about 7 years old) and the power light is brighter than a Supernova.
    It's a bright blue....so bright I can't focus on, or read anything, that is near the power light.
    I've threatened to do the very responses you received.

    Now that I got a laugh out of your post I'm reminded to get out the tape.

    Carry on....

    You guys are always awesome. Thank you very much. I'll open the thing and see if soldering would be possible, if not, go with tape.
