What Size Resistor For Led Turn Signals
How to Install Load Resistors for LED Turn Point Lights:
To add a load resistor to an indicator (turn signal) it has to be wired into each LED light seedling in parallel. I.eastward. The load resistor goes across the lite seedling connections, between the supply and ground.
A load resistor is required for each LED light seedling in the turn signal circuit, (you may just want to upgrade the rear of the vehicle? In this case if you're changing 2x filament low-cal bulbs you will demand 2x load resistors).

Precautions:
- Whatever installation is at your ain risk. Each vehicle may be different, or may have been previously modified.
- Disconnect the battery, when wiring vehicles.
- If you're unsure, use a qualified automobile electrician. As modern vehicles electronics tin can exist damaged easily.
Don't forget, load resistors tin can generate lots of estrus, so position carefully.

LED Resistor Wiring Diagrams:
A typical load resistor for a 21 watt plow signal lite seedling would take a rating of 50 watts, half-dozen ohms.
Note:
- This is only an example. So, delight check with your supplier, to ensure the correct size is obtained.
Calculating the Size of a Load Resistor:
To someone familiar with electronics, calculating the size of a load resistor may exist easy. But to anyone else, it could be a scrap confusing…
Therefore I'one thousand not going to attempt and explain in as well much detail, just just give an understanding of how the size is calculated.
- Explaining the Load:
- Calculating the Size:
- Why the Wattage is Important:
Why the Circuit Load is Important:
The load resistor replaces the load lost when the filament light bulb was replaced by an LED low-cal bulb.
In other words:
Computing the Size of the Load Resistor:
You lot can utilise calculations to obtain the size of the load resistor.
Showtime we need to calculate the difference between the filament light bulb and the LED lite bulb in watts:
A = The size of the filament light seedling (in watts).
B = The size of the LED light seedling (in watts).
The difference = A – B
Using Watt'south police force and difference between the filament light bulb and the LED calorie-free bulb (in watts) calculated above, we tin find the current (amps) needed to mimic the filament light bulb.
We volition then use the current (amps) calculated above to detect the resistance (Ω or Ohms) of the load resistor.
Why the Load Resistor Wattage is Important:
The resistance and the number of watts are the two parameters needed for obtaining the size of the load resistor.
The wattage of the load resistor is the value used in the calculation to a higher place…
The filament lite bulb (watts) – The LED calorie-free bulb (watts).
This volition requite you the everyman wattage figure, but the load resistor will get very hot (just like a filament lite bulb). So the rut needs to be prodigal using a much larger wattage load resistor (at least double).
One of the bug with this calculation, is often the LED low-cal seedling specification isn't readily bachelor, or is a bit vague. Which then makes calculations difficult (guesswork).
Researching on the internet, it seems a typical load resistor to replace a 21 watt turn point light bulb would use a 50 watt 6 Ω (ohm) load resistor.
Annotation:
- The 50w rating is to dissipate whatever heat.
A good supplier of load resistors should also be able to propose and assistance with your selection, if you are unsure what to buy.
