How easily can I replace the white LEDs in my LED party glasses with blue LEDs?
I don't have a photo of the glasses unfortunately, and I'm an amateur. There are 4 small white LEDs I want to replace. How easily can I replace the white LEDs with blue LEDs?
Great answer! I'm an amateur, but I've done similar work a few times before. I just hope I get the right blue LED, and luckily I have more than 1 pair of these glasses so in case I screw up I can change the LEDs on the other one(they're cheap too!).
White and blue LEDs usually have similar characteristics - or at least similar enough that you should be able to unsolder one and solder in the other. Just try to do the soldering quickly, so that the LEDs and the surrounding circuit does not get damaged from sustained heat.
Also, you DO have to get the polarities right. IF you have a volt meter, you can test across the LEDs that are IN the circuit to see which side is positive. When you get your new LEDs the slightly longer lead of the two will be the positive side.
Give it a try. You might not get it right the first time, but you will learn a lot more than if you did not try!
