At the risk of seeming contrary, would someone like to explain why LED headlights are considered desirable ?
I anticipate someone will say “They’re brighter, therefore better”. Personally I disagree with the “arms race” that is putting more and brighter lights on the front of every new model. The standard lights on my Jazz are perfectly adequate - passengers have commented on how effective they are - without needing to be enhanced further. Having unnecessarily bright lights simply annoys or blinds other drivers, especially those SUV/crossover marques with high-mounted lights whose drivers don’t understand the concept of maintaining a safe following distance.
The preceding discussion suggests they are expensive, so there’s no cost saving, and you may even be paying a premium to have them.
Presumably they have a lower power consumption than standard bulbs, but is that significant enough to result in a benefit to the owner (maybe better mpg) ?
So what’s the point ? Is it just a fashion/ego thing ?
It's a thing of brightness.
Imho they are not adeguate considering the price of the car.
First there is only one lamp for dipped and high beam, when quite all other small cars have two lamps, one for dipped and another lamp for high beams.
Second, Jazz headlights lack in light distribution (good in front of the car, but bad in side parts) especially when high beams are on.
Third, when you switch between dipped and high beam, there is an short moment of darkness, when one filament is switching off and the other is switching on.
I come from a Renault with an impressive halogen system (lamp for dipped beam, lamp for high beam, lamp for curve light, fog lights) and the difference in performace is clear. H4 halogen headlights are the cheapest solution for a car, and they provide the lowest performance in brightness, light distribution and glare.
