LED Technology is the newest type of lighting out there and one I feel will stick around for a long time. The reason for this is the efficiency of the lighting and the brightness of the bulb. LEDs are directional lights which means that when you look at an LED light most of the light shines out of the top of the bulb with very little escaping out the sides. This makes for a very bright light directly behind the LED. The advantage to this is that the bulb does not need any reflective lenses to direct light and they are much brighter to vehicles direcly behind the rider. Trust me when I say that if you want to be seen at night with a blinking tail light LEDs are the way to go. The other obvious advantage to LEDs is the energy efficiency. The bulbs do not have to be high powered to be seen. The directional aspect of an LED makes even the weakest of LEDs able to be seen by vehicles from far away. Of course this in turn equals MUCH better battery life and you can expect your taillight to go weeks of riding without needed a battery change. Don’t forget that LED’s will never need to be replaced for the life of your light and therefore are more cost effective in the long term.
