Without getting too technical, this simply means that the circuit experiences some additional current through the resistors when the LED signal comes on. So there you have it. Install one of these resistors into the circuit near your LED signal and you will increase the amount of current the OEM relay sees when the LED signal lights up Probably would be worth contacting them and asking for clarification, but their products have been really good in my experience. If you do a search for 6 volt on their website, it will recommend a different LED that also looks like it is listed as a 12 volt one. I love their products, but their website has always been a bit difficult to deal with. A colored LED will also work on less voltage, but you have to use a smaller resistor. (100 ohms works well for 4.5VDC) The LEDs that you found that said they didn't need resistors were probably a package unit that had them built in. Most modelers use the 'component LEDs' (my word) which are just the plain LEDs without anything else wired to them. However, if our voltage was 12V, we would have to rework our calculations to keep the same amount of current flowing through the LED. Our duty cycle would need to drop to 14.167% (1.7V divided by 12V) and our minimum PWM frequency would decrease to 14.285kHz (the inverse of [10us divided by 14.167%]). HOWEVER!, this is cause for concern. In the You can drive a 10watt RGB LED from a regulated 12volt supply the cheap way (with a bit of heat). Use three TIP120 darlington transistors (using mosfets means hotter resistors). Emitters to ground. Bases via three 1k resistors to three PWM outputs. LED anode to 12volt. LED cathodes via three current limiting resistors to the three collectors. If you are wondering, "What resistor should I use with my LED?", or if you were wondering what resistor you should use with 12 V or 5 V supply, then this article will help. In the diagram above, you can see the pinout of the LED. The cathode is the negative terminal, and this is the flat side of the diode, and the terminal on that side is shorter. Rearranging the first formula to solve for resistance we get the following: R = V/I. If we solve for Resistance then we get something like this: R = (15v - 2v) / .020A. The voltage value needs to be what is left over AFTER the LED's needs. In this case, our maximum voltage is 15v because it is from a vehicle. What type of circuit should I use? Is one better than the other…Series, Parallel, or Series/Parallel? The requirements of a lighting application often dictate what type of circuit can be used, but if given the choice, the most efficient way to run high power LEDs is using a series circuit with a constant current LED driver.
