1. One reviewer said you don't have to use the resistors. Will this make the lower voltage LEDs burn out quicker? 2. How will I know which resistor goes where ?

If you don't mind brightness varying or burning out a digital output or a power supply when the LED fails, then don't use a resistor. It doesn't matter which lead of the LED the resistor is connected to.

Find one with a higher wattage equivalent, they work but not as bright as i would like.I also need to keep one of the original bulbs in the circut. (7) LED & (1) regular filament bulb.If I didn't bulbs would constantly flash. Has to do with Malibu transformer voltage regulator.

I can only can give my opinion but, in any past experience I have had regarding LED displays like this is not good. Generally, you would have to replace The whole display module.... But I might be wrong. :0/

180 ohms for the green and blue 270 for the red. The green and blue Led's require a little less voltage than the red one. The red led has an ~1.8V drop. The green and blue have about 3.0V drop assume a 180 ohm resistor sets the green and blue Led's @ 11 mA and the 270 ohm resistor does the same for the red led. These were my calculations for the red = ~1.8V / 270 ohms = 0.0118 A or 12 mA and Green-Blue ~2V / 180 ohms = .0111 A or 11 mA. The resistors are based on 5V Vcc. If you are powering them from 3V3 the red is 180 ohms and the green / blue is 120 ohms. The ohms law formula I used was I = E/R and the values are the ones I use in practice.R K Johnson Sr. 180 ohms for the green and blue 270 for the red.

Yes, you'd need three 100 ohm resistors. Check out this website, http://led.linear1.org/led.wiz for building more complex LED arrays.

Yes, that will work perfectly fine. Be sure to put a 330ohm resistor in series with the LED to keep it from burning out. However, since that limits the current it may affect the performance of the booster at lower voltages. It would be best to place the led in series with the IN- terminal. Remember, electricity always flows in a loop, from + to -. Just make sure you have the LED the right direction and don't forget the resistor and all should he fine.

Yes you need to have these as these are resistors which will prevent the lights from flickering. LED lights require less power to operate and if you don't use resistors "in line" you run into issues ( turn signal light will flash rapidly and set off computer warnings on some cars). I have had to use resistors with all my led light on my 2013 Jeep Wrangler

No they do not come with resistors. But I received several extra LED's in case a few were faulty. It's very honorable of the seller, and the resistors can be found here for 4.50 per hundred

You will not need resisters unless they are for turn signals. The turn signals will flash very fast without resisters. I found an easier way to control the turn signal flash by replacing the original flasher with a led turn signal flasher. They are inexpensive and Amazon carries them.

It depends on the number of LED's, and whether you are wiring them in series or parallel. In a 12v circuit, For a single LED (or parallel wired LEDs) with a 3v drop and a desired current of 15mA, you would use a 660Ohm Resistor for -each- LED. You can use the calculator at ledcalculator.net for more scenarios such as series wiring.

I second the resistor answer here is a helpful link to an example of one that will work for turn signal flashers. http://www.amazon.com/gp/aw/d/B00UNG3EXQ/ref=mp_s_a_1_1?qid=1429569263&sr;=8-1&keywords;=resistor+for+led+autoπ=AC_SY200_QL40&dpPl;=1&dpID;=51Opvye%2BxxL&ref;=plSrch

Generally less amps are pulled by a led vs a incandescents hence the need for the resistor which should be wired in parallel with the turn signal part of the circuit check the wiring has to be a short to ground somewhere. A bad bulb is possible but that would likely follow the bulb if shaped left to right. A wiring short or miss wire is most likely.

yes, it should work fine,Leds are very low amperage, you might have to use a resister to limit voltage depending on the LED Rating.

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.

5 amps tends to work best. If you go with a lower power they will not be as bright and technically it can handle more but it will shorten the life of the LEDs.

You can purchase the resistors at the same time you purchase the lights. Usually they will pop up at the bottom of the screen under " Customers who purchased these often purchased.....". It's easy to install there's only 2 wires and all you have to do if find your "hot" wire and the other. You can find these with a simple test light. Yes there's instructions or you can read the comments of those who purchased them, that's where I confirmed my instructions.
