Why Buy Automotive LED's?

The Benefits of using Light emitting diodes

1. LED's efficiency (require about 10% of power, vs. an incandescent)
2. Produce far less heat = safety & long life
3. Vibration & shock resistant
4. Less susceptible to variations of heat & cold

LED's (light Emitting Diodes) were first used in the computer industry due to their minimal power requirements and heat output. Unlike incandescent bulbs, which produce heat as a primary function by heating a tungsten filament to extreme temperatures in a vacuum bulb thereby causing it to glow and produce light throughout the ENTIRE visible Spectrum (including ultraviolet) and wasting a lot of heat.

LED's produce light photons as a primary function and produce light only in the specified spectral frequency. This means that there is NO ultraviolet (unless specifically tuned to produce it) and that no filters or lenses are required to change colors. And since the power is producing light primarily, the light does not get hot enough to burn or damage plastic lenses or components. Further due to the design, they are more resistant to shock, vibration and or damage (a major concern in automotive applications).

LED's have an extended lifetime due to the reduced heat stress on internal components. The led unit itself does not "burn out" as light production just begins to get less bright, Lifetimes average around 50,000 hours or more ( 15 to 20 Years of normal use) the lamp is regarded as failed when light output is down to 78% of original brightness, again 15 + years.

LED's have no "warm up phase" in cold weather, unlike fluorescents or Neon since there is no "gas" to attain luminosity. They are "instant on" and at full brightness immediately.

LED's are safer than regular auto lamps as they:

Produce very little heat

Do not "burn out"

Produce a far brighter light at a fraction (approx 10%) of the power required to light an incandescent bulb.

LED's are being produced for nearly every application used in automobiles and are very easy to change with ordinary tools. However for some applications, like turn signal bulbs, led lamps do not use enough power to activate the bimetal contacts in the turn signal flasher unit and need to have a special flasher unit installed for the signals to flash correctly.

LED's have undergone an enormous evolution in light from the first weak glow we saw on computer faceplates to the high energy units of today rivaling and in some cases exceeding the light output of very strong incandescent bulbs. The higher cost of an LED is now actually a cost savings due to the lifespan, and if replacement labor is considered they become remarkably cheaper.
