Who has LEDs? Do they need a Load Resistor? What wattage?

[Homeboy981]

O.K. I am with ya on where to get it but…

The wattage of the bulb it is replacing is 21W…the LED pulls a watt or two….wouldn't 50 watts be too much resistance for the circuit? Don't want to over tax the circuit-like we are being over Taxed in US, but I digress. They make 25 Watt 6 Ohm resistors too, would not that be more applicable? Panameras, Relays…is that a UK spec thing or can you elaborate?

I almost wish I had not made my car look better at this point! But I sure DO NOT miss the orange!

I saw a 996 video that used a AWFL-15 LED Flasher. Porsche 996 LED Blinking with LED Flasher - YouTube
Which I can't seem to find..
I did find this link.. German/European model CF13GL-02

Dude - ohms are resistance, not watts. The wattage rating is the amount of power (voltage squared over resistance, or current squared times resistance, or voltage times current) that the resistor can handle without melting, so you need a resistor rated above the power load. Too big is obviously better than too small, and there is no harm in overkill.

Remember: Twinkle twinkle little star, power equals I squared R.

Mark T, thanks for the inspiring poem. I guess I missed that one in school.
