Does automatic/adaptive high beam still work when fitted with LED headlights or driving lights

The simple answer is YES. I will explain why below.

The adaptive high beam is typically controlled by a sensor located within the windscreen and is not dependent on any modifications or additions made to the headlight itself. The headlight is only receiving power and is the least intelligent part of the system. Making any additions or modifications to the bulb or wiring harness will not affect the adaptive high beam.

In essence, you will be picking up a high beam signal down at the headlight, so whenever the bulb is turned on or off via the stalk or adaptive system, the bulb or wiring harness will react as such.

You may find that your car can be a little confused sometimes, and think that the, now very bright, street signs are oncoming cars, but most systems will quickly figure out that this is a false positive.
