You can now get LED replacements for 4x6 inch head lights for older vehicles. OEM part numbers are H4656, H4651, 4651, 4652.
Looks like these are commonly made using 15 CREE LEDs that consume 3 watts each.
The ones I bought use 1.1 amp on low beam and 2.8 amps on high beam.

To use them as any kind of low beam that will be aimed at on coming traffic the beam will need to be pointed at the ground, 10 to 15 feet in front of the vehicle and the top of the light partially blocked off.
I think I will just use these as the high beams.

Its just like a big formless spot light.

I bought some 4x6 inch projector+H4 upgrade lights a few years ago but never used them because 3 years ago, the H4 LED selection was just too limited. Then I forgot about the project.
