"light them up using squarewaves so very low power consumption and longer LED lifespan compared to continous on"




what is squarewaves??

 

[votech]

Pulses of On and Off at certain frequency. If you have a scope, it looks like Squares or rectangles depending on the on/off time. Anyway, it is use for blinking the LEDs at high speed however this blinking will not be noticeable by the eye. Alot of LED torch light use this concept to save power.

the BMW 7 series rear LED lights uses squarewaves....right?

no wonder if you look at the lights from the corner of your eyes, the LED appears to be blinking.

LEDs

simefly, add more bright white LEDs la.. A pair too insignificant to be seen. I hv 5 at each side, still too small, plan to hv 10 each side.. Yes, these LEDs ain't cheap, so remember to put resistors to prolong its life, and also your battery.

LEDs can't really illuminate as well as normal bulbs but the direct beams from the front of the LED can be very visible from a distance. That is what a daylight driving light is for, to let ppl notice you are 'there'; during the day (well, maybe not during noon when the sun is so damn bright) but not to replace existing car lights.
