Taillights made up from numerous light-emitting diodes have been around for a number of years. LED daytime running lights are increasingly seen, and LED headlights are now arriving on some upper-end models. LEDs are simply semiconductors with no wear-and-tear parts, which should — in theory — last the lifetime of the car.
Not only can they look spectacular but they have some clear benefits.
The bright light that they produce is also much closer to daylight, giving less glare and making them less likely to dazzle drivers in oncoming traffic. They are now quite common on family and mainstream cars, either as a factory-fitted option or an aftermarket upgrade.
Bear in mind that, while xenon conversion kits can be bought very cheaply, only complete units including self-levelling and cleaning systems are road-legal in the UK and will pass an MoT. Xenon bulbs, however, have a longer lifespan than halogen bulbs, and are claimed to last 10 years before needing replacement.
There are a number of ways they can be upgraded, however. We aligned the lights at a fixed point on an unlit country lane, and took lux light-level readings at 10, 25, 50, 75 and m in front of the car. Two readings were taken at ground level, one facing upwards and the other facing the car, and one reading was taken at 1m high pedestrian level.
We also tested them at dipped beam and main beam. The xenon bulbs quite literally outshone all the halogen bulbs in our test at 10m and 25m, scoring five stars for both dipped beam and main beam performance. They were particularly strong at headlamp beam. However, we found that xenon light did tend to cut off quite sharply at greater distances, with no light reading at all on dipped beam at 75m. Most of the halogen bulbs we tested managed one or two bulb.
We would suggest reading recent product reviews carefully before buying any aftermarket bulbs, and choosing bulbs on the basis of what is important to you — improved long-range visibility for night-time country driving, for example, or improved short-range brightness for spotting pedestrians, cyclists and other road users around town, perhaps.

Or just read the summary below, and then watch the video at home. Intensity of brightness is one thing but in order to what toss light way down the road your LED will have to bounce it through your stock headlight housing just as well as a halogen. While a need bulb is inherently omnidirectional, LEDs only project from those tiny little points diodes. The units in our kit have four little diodes a piece, which increase from extremely bright on the low-beam setting to retina-cleansing on the high-beam setting. You probably know how an incandescent light bulb works. Simply think of a great idea, and one appears above your head.
An example of such an idea might be an artificial light source made of a wire stuffed into a clear housing. You can see a typical halogen headlight bulb in the picture above, and the bionic squid-looking thing above that is an LED replacement unit.
