Some automobiles use pulse code modulation to regulate the apparent brightness of the lights, at a frequency many people can see.

It wouldn't be noticeable with a slow-to-respond incandescent bulb, but it certainly is with an LED.

Worse, some cars seem to come from the manufacturer like this.

Irritating!!!

Personally I hate computers in cars. A rock-solid self-contained fuel injection system instead of an inefficient carburetor, sure, that's okay, but anything else is going to be an expensive headache someday.
