LED headlights offer great illumination - but the cost of replacing a burned out LED headlight can be considerable...I have not found any estimates for the 2019 Insight but, WITH LABOR, I have seen other cars having the replacement cost being $200 or even much higher. It's likely the Insight headlight cluster with all the bulbs in it is actually a single integrated unit (one bulb goes, all have to be replaced).
What shortens the life of LED bulbs is actually turning them off and on repeatedly (true, for even the bulbs used in household use). It seems to me that a lot of cars I see at night with only one headlight
operating are disproportionately those cars with LED headlights. You would think these LED headlights would be engineered to last the lifetime of the car, but apparently this is not always the case.
Drive safe, but something to think about with this automatic on-off high beam feature. I would also be interested to know if anybody has any idea how difficult/expensive it is to replace the headlight bulbs in this car.
