Some consider this unfair and have campaigned for the legislation to be updated, but all we can do is advise you of what the rules are.
#HALOGEN WORK LIGHT UPGRADE#
There are many aftermarket suppliers offering LED headlight replacement kits for cars with halogen lights (a kit is required as power and cooling differences between the bulb types mean you can’t just swap bulbs), but unfortunately it is not legal to make this upgrade due to legislation that does not provide a certification process for aftermarket LED headlights. Can you replace halogen bulbs with LED bulbs? And with most manufacturers already shifting over to LED headlights – over 60% of all new cars globally have LED lights as standard – this should be the case here as well. However, prices always come down as new technology becomes more commonplace. On a budget car that is 15-years old, a blown set of LED headlights may write-off the entire vehicle. These costs are partly down to the fact that most manufacturers use sealed headlight units, so you have to replace the entire headlight assembly instead of just the LED unit. A recent study showed that a replacement LED headlight for a Suzuki Swift cost almost £700. LED headlights have a far longer projected lifespan than halogens (up to 10 times as long), but when they do give out, they cost far more to replace. Some designs – often referred to as matrix technology – can even switch off individual LEDs to avoid blinding oncoming vehicles. LEDs are far more versatile than halogens, too, they can be configured in a variety of shapes and sizes, and their hi-tech nature allows for more nuanced adaptive headlight control. This is especially important in EVs, where every watt of power saved means more miles between charges. They are approximately 80% more efficient than traditional halogen bulbs, this lowers the strain on the car’s electrical system which in turn can improve fuel economy. The big benefit of LED headlights is their low power usage relative to the light they emit. What are the pros and cons of an LED headlight? LED headlights emit a very bright white light. This electrical process is what illuminates the road ahead.
LED is an acronym for Light Emitting Diode, LED headlights produce light by passing electricity through tiny little semiconductors which emit photons. The dimmer light quality and yellowish glow is less disturbing for other road users, though. They also don’t shine as brightly as LEDs, as some of that energy usage gets converted into heat instead of illumination. This can put an extra load on the car’s electrical system and can impact overall efficiency over time.
Halogen bulbs aren’t very efficient, though, consuming around 80% more energy than an LED headlight. That said, the average cost of a halogen bulb is between £5 to £20, so having to replace them every few years is hardly going to break the bank. Replacing a halogen light bulb is also a lot simpler than swapping out a faulty LED unit, however, you may be doing it more often as halogen bulbs have a shorter lifespan than LEDs. Halogen light bulbs are commonplace in the majority of entry-level cars around the world thanks to their low manufacturing and replacement costs. What are the pros and cons of a halogen headlight? Halogen headlights have been around since the 1960s, they are a modified version of an incandescent light bulb (the ones we all used to have in our homes) and comprise of a tungsten filament enclosed in a glass bulb filled with halogen and a mix of other noble gases. What is a halogen headlight? A light-emitting filament, similar to the kind used in halogen bulbs Manufacturers are slowly phasing out halogen headlights in favour of LEDs, but both have their benefits and in this article, we will delve into the pros and cons of both types to give you a better idea of which one is best for you. The most common types of headlights in use today are halogen and LED. Headlights have been around since the dawn of the automobile, evolving from the early acetylene lamps already in use on horse-drawn carriages, to the adaptive laser units you would find on the latest high-end model.
