Wow, I think from memory H4s are 750 lumens, the LEDs I fitted are 6000 so 16000 must be very very bright.
Don't other drivers at night get annoyed with the new bulbs?

I notice also the heat sink on the bulb is inside the headlamp shell. I have no idea how hot they get but my heat sink is outside the shell.
