I pulled the halogen bulbs. Just as I suspected they are high beam only.
These LEDs units want to stick out about an 1/8 of an inch more than the original head light. Surprisingly the head light pocket needed no modification and when you tighten down the head light bracket everything goes right into place.
I did have to cut the low beam prong off, aka the redneck H4656 to H4651 conversion.

The factory halogen bulb draws 3.8 amps with just a 12 volt battery and with my little battery charger hooked up to my battery the halogen draws 4.1amps at 13.8 volts.
Which adds up to 57 watts on near charging voltage, could be right at 60 watts at 14.4 normal charging system voltage.
These should only be 50 watt head lights.
To be fair, note these are 35 watt LED versus what turned out to be nearly 60 watt halogens.

Not the huge savings I thought it was going to be, only 1.3 amp per high beam bulb.
That's 2.6 less amps to draw during EOC or with the alt disconnected.

Playing with the halogen high beam (H4651) they appear to throw a wider beam, but the LED high beams appear to be brighter over all.
The good H4651 high beam lamp is $22 at O'rielly auto parts.

I wont be able to road test it tonight, as soon as I touched the head bracket screws on the passenger's side the ancient plastic head light aimers just crumbled. As soon as I go over a bump the pass side high beam will go cross eyed.
