Difference between vleds and iJDMToy Switchback bulbs

Hello,

I am considering changing the switchbacks to LEDS and would like to have the white bulb that changes to amber when flashing.

I am hesitating between these :

and these :

I am wondering why the vleds are twice as much money for what looks like a 42 leds bulb vs a 60 leds bulb. Am I missing something ?

Also, does any one know if in areas where DRLs are mandatory, the switchbacks could be considered DRLs ? I figure that with the switchbacks in place, I could simply pull the fuse out of the DRLs and use the switchbacks as DRLs.

Thanks
