Re: How do you know if you have Xenons?
Crispdust, You're right about leds on the back of 3 series Beemers, very bright when sat behind one in traffic
LED technology has come on leaps and bounds in the last three or four years, much of it is used on push bike lights, don't laugh, some cost upwards of 300-400 ukp. Many off road riders use them for nightime mountain biking (fairly hazardous sport that!)They are very powerful and emit a pure white/bluish light, kgb you are right they do generate an awful lot of heat though. The main advantages are the small amount of power that they use compared to normal bulbs, the fact that they last for ages compare to normal bulbs and they are extremely compact, even with the reflectors that are required to creat a usable beam. This will allow designers of cars to place extremely sleek lights in the nose of cars in the future.
