LED tail lights

An LED is a DIODE not a resistor.

LIGHT EMITTING DIODE

Are you running resistors in your taillights :^)? If not, V = I

You're not even accounting for the voltage drop imposed by the diode.

I love autists like you guys. I learn a lot from your angry rants

with no resistance then I would be as much as the power source could provide, so really fucking high running off a car battery.

Voltage drops in a series, which is how taillights *can* be wired.
Think of how many times weekly you open/close your trunk, how often your car sits out in the heat daily while you wageslave away, and then freezes at night. Now think of how frequently your taillights give out as is, now shrink your tolerance gap by half. That's an exponential failure rate. Do you really want that?

You don't understand how wrong they are, though. The car is already stuffed full of stupid little electronics and gewgaws. It would be pretty much nothing to do PWM or something to simulate a fade without some stupid analog dimming crap, and then you wouldn't need a relay anymore.

Then you could program the radio to make clicky noises for all the people who would be upset they can't hear the blinkers go click-clack-click-clack-click-clack.

What tolerance? Driving an LED is not rocket science. They're EVERYWHERE.

Also, you're forgetting to model the resistance of the wiring and the internal resistance of the battery in your ridiculous attempt to show off that you like to drop a diode across a car battery to watch the smoke come out. Please never design my car.

I thought they went with the incan turn signals so they could get away with a old school flasher. I don't know why else they wouldn't go full led. I don't think it's a fade issue. Plenty of trucks and cars have full led setups that just blink normally.

resistance of wiring? 0.5 ohm
if I wanted to watch you smoke a diode, I'd tell you to hook up your fancy LED taillights and LED headlights and go drive down the nearest country road with your $20 chinese ebay kit and blind every unfortunate soul in your path, they probably wouldn't survive the trip home.
