Hello, All
I have replaced in my Prius 2 phev the standard halogen H4 bulbs with led
The led H4 bulb:
The patern in low beam, halogen/led:
The patern in high beam, halogen/led:
The halogen bulb use 61/67 Watts in low/high
The led use 20/20 Watts.
3 times less for more light, estimated twice. The dsc camera use half the time to take the picture with led.
