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.
votech, expensive but not until rm500 la... Piaa really sotong us...
