I wasn't aware Honda was using the old bucket still. HM36 I think is the marking. That replaceable bulb lens looks like it appeared in 2001 with the 250 Nighthawk. The biggest problem is finding a unit with the mounting ears in the correct locations, from what I've read the aftermarkets all seem to be offset and some with larger threaded holes.
Since the headlight bucket is the same one as the original CB400T1, 2 and A models then I would do the simple thing and buy the later headlight, 33120-KPJ-670, with the changeable bulb and use a H4 55/60W bulb which was standard equipment. Headlight change took place in 2001.
Original bucket fits

So if i am reading this right and i also wanted to update my headlight on my 78 cb400a, i can get the headlight unit 33120-KPJ-670 and any H4 55/60W bulb and i should be good to go? Just making sure before i make the buy. thanks!
Yep, find a headlight assembly from a later model CB250 and bolt it in. Or if your bucket is good then buy the bulb ass'y. There's some on eBay. The charging system is sufficient for the 55/60W bulb, I've been running one for 7 years now
