They are halogens.

The AE out on one side is a property of LEDs. Often times, PWM is used to dim bulbs as is the case with your stock halogen bulbs. The PWM frequency is too fast for the human eye to see but through a camera's slow frame rate, you see flickering. This does not happen with halogen bulbs since they have a "warm up" time and are not instant one, like LEDs are.

No they won't generate errors. But if you want to run them as DRL then you do need to code them.

Well, yeah, it's supposed to be. Sometimes the illusion of continuous illumination is due more to the physical response of the lamp (e.g., the heating & cooling time of a filament) than persistence of vision. Plug an LED into such a circuit and the pulse frequency can become suddenly, annoyingly obvious.

Early Cadillac LED tail-light systems have this problem and it drives me insane whenever I'm stuck behind one. They're OK at full intensity (braking) but the pulse frequency and duty cycle chosen to dim them is (just barely) perceptible to direct vision. Worse, every time I blink or flick my gaze, the stroboscopic effect rewards me with a dozen images of the LED arrays.

Thankfully, GM seems to have corrected this in later models.
