What happens if I use the wrong resistor?
The equipment will cease to function in short order either by the resistor itself burning up, or by the heat it generates burning up an adjacent component or possibly the circuit board its mounted on or even foil pattern on the circuit board, or maybe all three.
What size resistor do I need for LED tail lights?
If you only installed 2 LED bulbs, one for each of the tail light/turn signal/brake light for example, then you need 2 6 ohm resistors. The wattage should be 50watts.
Why do you need a 330 ohm resistor for an LED?
Detail: 330 ohms may be used by some people as a “get you going” value that works “well enough” in many cases. The purpose of the resistor is to “drop” voltage that is not required to operate the LED, when the LED is operating at the desired current.
Are LED load resistors safe?
They do not perform any physical action and can overheat and melt insulation, causing short circuits and possible fire hazards. … There are special load resistors designed for LED light circuits which, when correctly installed, minimise the maximum temperature of the resistor.
How many LED load resistors do I need?
So if you replace 1 set of bulbs (the front OR rear bulbs) you will need to install 2 resistors (one for each side). The 3 OHM is the equivalent load of 2 bulbs. If you replace your front AND rear bulbs (4 bulbs total) you can use use two 3 OHM resistors.
