Thanks everyone!
Got the bulbs from superlightsled and mentioned 'Non-directional'
and it works !

My guess is that you have used one of the following bulbs from SuperbrightLEDs website, that can be searched with the filter set to 'Polarized - NO' on the left column under the Car bulb, Miniature Wedge Base category.

Some DC bulbs have in-built rectifier and are therefore non-polarized.

Did you use WLED-5X which has 5LEDs or WLED-x4-x which has 4LEDs or WLED-x-x which has 1LED ? 

Any pictures of your bulb ?

That's exactly how I searched them polarized 'no'

However when I received it, the package said polarized non-directional

This is what I ordered:

WLED-G4-90 Green Wide   
WLED-B4-90 Blue Wide

WLED-G4-90 Green Wide   
WLED-B4-90 Blue Wide

These are 4LED bulbs with 90 degree beam angle, which are strictly speaking polarized bulbs but due to in-built rectifier act as Non-Directional.

Way better than original OEM bulbs and glad to see that they are working well.

And I want to say thank you once again to all who helped. I had hard time reading turn indicators in day light earlier. Now it's so bright, can't miss it.
