Hid's do not work well in the H4 system and it is more complicated than just more light.
What the newer H4 leds have is a better focus so that the light gets projected down the road correctly.
plus they have the shield which gives the sharp cutoff required to prevent glare.
I have over 30k miles now on my F2's in my bike and about 10k miles in my wifes van.
I really marvel on how much better I can see with the better lighting from just the low beam.
No one has ever flashed back at me..... ( I commute after dark in heavy traffic....)
If I kick on the high beam. wow......
This is the bulb I was looking for and is what I believe you are hoping to find.
I am not making any money off of this,
I just wanted a bulb that works right - something the experts told me could not be done.......
Now here is the kicker....
Each integral beam headlamp must be designed to conform to the photometry
requirements of Table XVIII of FMVSS No. 108 for upper beam and Table XIX of
FMVSS No. 108 for lower beam
The maximum intensity allowed for each upper beam headlamp is 75,000 cd;
This is equivalent to 150,000 cd for a headlighting system.
A pair of F2's are 84,000 Cd on high beam in my ST1300 ..... which is less than DOT spec
The low beam has NO max spec for the hot spot in FMVSS 108 rather only limits for glare.
No such thing as an illegally bright low beam...... ( yea - I was surprised too )
The H4 system is so good that the F2 with its sharp cutoff measures under the glare test limits....
Now I am only one data point. We are on track to meet the federal requirements but.....
This does NOT make this bulb legal yet, just hope we do not have to wait the 21 years it took the halogen bulb to get approved...
