Although it was about (630 Ω) in the LED resistance calculation, it is substitute for (1 kΩ) of stock and it is used for (AT cooler fan) (auxiliary light) SW.
The resistor is placed between the SW terminal close to the LED terminal and the LED terminal on one side is grounded.
It is a product of Nippon switchgear and reliable. Because there is no built-in resistance in the LED light-emitting part, it is somewhat troublesome to attach a resistor to the terminal. This is unavoidable because it emphasizes versatility. It is a product without any problem in operation. It is the product I want to purchase next time.
For use with a vehicle auxiliary light (LED) I use resistors (lit on)) on the line. Even for back fog, since it is used with LED color difference (genuine SW) and because it is exchanged and it fits in two rows, it does not need to process the vehicle panel, so it is handy.
