Have you ever done any lights on an older tractor with the 4x6 rectangular sealed beam headlights?

I finished the lights that I ordered last week and they look great, now I want to do more but I want to keep the factory look on the front lights of the 2-155 and later on I'd like to do the front of the 6144 also.  Both of these have sealed beams in the front.

Here's what I've found so far, from the looks of it I would need to order the H4-2 VVME kit to get a Hi/Low beam with only one of them being HID.

 Here's the sealed beam conversion kit.

Let me know if you know of something better or cheaper.

Last night when I quit for the night it was getting pretty dark outside and I only had 2 lights done (one on front & one on rear) and the difference between the 20 yr old factory lights and the HID's was amazing.

Thanks for the help.
