![]() Swapping a faulty bulb on one of these systems is a job you're unlikely to have much success with unless you have an electrical engineering degree. This technology is still very expensive, and regular maintenance on these units is probably best left to the experts. Obviously, seeing more of the road is a huge plus for driving safety, but all of these good things come at a cost. These lights can also illuminate twice as far down the road as an LED light, ensuring improved visibility and safety in most conditions. The kit I used features CREE LED bulbs that have an output of 3,200 lumens. The main advantage is a massive increase in road illumination and therefore improved safety when driving at night. Getting up to the necessary speed to use the laser headlights shouldn't be a problem for the blinding fast performance EVs BMW makes. All vehicles fitted with halogen headlight bulbs from the factory are suitable for LED conversion. In fact, the light output is so bright that BMW doesn't activate the laser feature on some of their headlights until the car is moving past a certain speed, and they also incorporate an anti-glare measure. This light is many times brighter than LEDs and cements the laser headlight as the king of the lumen wars. When LED alignment gets skipped, oncoming drivers are. ![]() When the laser's photons are shining on the phosphorus, a huge explosion of dazzling white light ensues. While halogen filaments deliver 360-degree illumination, LED bulbs typically emit light with a pair of back-to-back 180-degree planes. These lights are a huge safety feature and provide infinitely more functionality than a halogen bulb ever could. Some LEDs have a life span of almost 20,000 hours (that’s about 18 years if you use the headlights for three hours per day, 365 days a year). Imagine the benefits of always having your high beams on, but in a tailor-made way to avoid blinding oncoming traffic. LED headlights are often fitted within a cluster that may look similar to a halogen headlight (a reflective prism), but that’s where the similarities end. The best part about an advanced matrix headlight is the system's ability to communicate with sensors scanning the road and adjust their beam pattern in real-time as a result of whatever information the sensors relayed. Not only this, but manufacturers like Audi are fitting their vehicles with advanced "matrix" style LED lights. The halogen headlights with H7 bulbs provided up to 450 lumens of intensity (luminous flux on the road low beam) and a light colour temperature of 3,200 Kelvin (slightly whiter warm light), with a consumption of 55 watts in the low beam. LED lights also allow for headlight housings which can be stylized however the manufacturer sees fit. ![]() LEDs can be used to replace all filament-based bulbs in a car, especially in the interior, where it's better to use lights that don't drain the car's battery or alternator. Halogen bulbs waste most of the energy they use by producing lots of heat in turn, an LED light is supremely efficient when producing illumination. The fact that they run so cool indicates the efficiency advantage they hold over halogen bulbs. ![]()
