  1. To be fair, many modern headlamps are computer controlled and do more than just turn on and off. Some of them are linked to the steering and even have adaptive patterns that avoid oncoming traffic. New software may make use of programmable features, so using the wrong lights could cause a malfunction due to sending the wrong signals down the CANbus. Should we have this level of complexity? That's a separate issue. But it isn't as simple as "manufacturers evil".
