Could you extend the life of the LED, by installing a resistor before the lead?

In my opinion, the LED is worthless in the first place; it is VERY small and you can only see it in the dark. I used a much brighter LED in the panel I built and placed it just above the switch. So.....not sure if the life would be extended or not...... Hope this helps,

Not sure... i havent had much success with these switches, wiring them like one should doesnt always work... may be some of them are faulty internally

I increased the time by soldering a cap on the back side across the existing cap.. something like double or triple the value of the original. I do not have access to the board, so I cannot tell you what value I used. It was a long time ago [my fading memory]. I do not know how large a value can be used and still have the timer work reliably. Experiment!

Assuming you mean you have an AC adapter that outputs 12v DC, you'll probably burn out the led without putting a resistor in the mix. LEDs typically only need a few volts to light

Yes, that is what they are intended to do. However, it is not easy to attach these to the LED strips so that the connection is good and they adhere well. I expect to need to replace these with soldered connections when these fail. But for the price, you may find these worth a try.

install a 1k ohm resister in parallel with ONE of the bulbs. The leads will fit under the caps. I have done this and it works. You only need to do this if you have exit delay lighting.

you can use 5050 SMD RGB Color Changing LED strip, Strip to Strip so no soldering is involved

you need to add one on the positive lead. the diodes are polar so make sure the white line is on the load side.

It's an LED on a circuit board, thus not practical for replacement by the average person, even though its accessible. I'm presuming the life of the unit would be something like 20000 hours (2.25 years continuous), based on other LED bulbs, but that's just an educated guess.

You may wish to start small, http://www.talkingelectronics.com/projects/30%20LED%20Projects/30%20LED%20Projects.html and this is a good resource as well http://www.hebeiltd.com.cn/?p=zz.led.resistor.calculator

Short answer is no. Long answer is yes, IF you are mechanically and electronically inclined and don't mind soldering them in place yourself. LEDS should last for years, so I wouldn't worry too much about replacing them, just buy a new sign in 10 or 12 years

The threaded area is made of plastic so temperature is their main concern. LED's should be fine.

I am not sure you CAN replace the LE D..I've had both of mine for over 2 years and they are still working perfectly.it's my understanding that an LED WILL LAST ABOUT 20-30 THOUSAND HOURS. if they die before me I will be surprised!

Yes, before the bulb. You might have to use 2 if you have LEDs in front and back.

I personally habe no problem with mine so far.usually, Leds do last over 10 years but cheap components makes problems especially when it's connected without ground wire.

You can simply enough solder the connection together if you're confident with soldering. Else buy the LED strips with the four pin connectors on each end and connect the two strips together.

No. It mentions on the package that the LED never needs to be replaced. Usually, LED lifetimes are rated in thousand of hours of operation. LEDs are not like light bulbs where they burn out or fail because the bulb got bumped and the filament broke.

That would depend on the output that the battery puts out. If the power goes more than 3 Volts then the LED would need resistor.
