Hello,
@Essarr
As you have said earlier, indeed LEDs takes nanoseconds to turn ON but when fitted to indicators, they are flicker faster then stock bulbs. Is it normal? and it acts same in your car too? When turned ON as Emergency Lights, all LEDs flicker slow like normal bulbs.

Apologies for the delay, I been out of circuit for a while. Yes, LED indicators bulbs do flash faster than normal rate.
When I first changed all for indicator bulbs to SMD/LEDs, they seemed to be flashing at the correct rate. That was because I used the 'hazard' switch on the dash to test them when I fitted them for the first time (a mistake because I think it is a controlled flash). It was only when I was out on the road, I discovered they flashed faster with indicator was used. For now, I have re-installed the original WY20W bulbs at the rear and the flash rate seems to be almost normal, though the fronts are still amber LEDs. I did not bother changing the side indicator bulbs at all, left them with originals.
I am not an expert, but my garage electrician says adding an in-line load resistor to each of the rears (or all four) will fool the 'computer' to think that the OEM bulbs (and its load) are still in place. Practically speaking, the use of LEDs is not really about power savings in the car, but more to do with longer life of the bulbs. I have to do this 'resistor' project sometime in the near future.
This is the calculation given by my electrician: The 20W bulb draws about 1.75 amps, while the LEDs draw about 0.5 amps. A load resistor of 10 amps rating should get the LEDs blinking at normal rate. I think one has to go back to school and Ohms Law (V=IR) and that is probably where one would arrive. Over my head, anyway.
Has anyone else reported this faster blinking of LED indicators?
Edit Add-on: Further to my response above, this page tells you what type of resistors you should buy for LED indicator bulbs and what you should not: http://www.ebay.com/gds/Load-resistors-for-LED-indicator-bulb-replacement-/10000000010344226/g.html
