This sealed beam does not have the "STANLEY" logo in the center of the lens nor "MOTORCYCLE" on the bottom of lens.  The outside back of the reflector has a brass tower the 3 terminals protrude from.

Stanley's sealed beam lights I've seen have:

1.  "STANLEY" logo in center of lens
2.  "MOTORCYCLE" in raised letters on bottom of lens.  
3.  glass tower with 3 terminals

Is this a motorcycle bulb ?  Or is it automotive ?

If memory serves correctly, these brass towers are seen on sealed beams used on smaller displacement Japanese motorcycles..... ?  (seem to recall reading this in a post, on this DB or elsewhere.)

Dear Steve;

The headlight showed in the pictures is a Stanley HM24M/S model.
On internet i found one file that shows that this headlight is approved for Honda motorcycle part, see pages 3, 4 and 5 (yellow), not a car part.

HM-20/with Stanley HM-24M-S

http://www.vsp.state.va.us/downloads/VA_Motor_Vehicle_Approved_Equipment_List/11_Headlamp.pdf

In my modest opinion, the Stanley headlight with the logo in the center could be a late production part, on ebay i found only this type on CB 750 from 1976-1980, and with the motorcycle write could be a generic part, just conjecture.

On Ebay there are a lot of CB450 headlights from the same era (K0/K1/K2) that donīt have the logo in the center.

I think that it is easy to find a CB450 Stanley headlight because it is a 12V 35/25W , that may last more than a 12V 50/35W , more difficult to find .

Could someone confirm that the original sandcast headlight is 50/35W?

I hope this can spice up our discussions.

Sorry about my English.

Thanks.

Marcello

Stanley's were fitted to sandcast. 

Koito's were used beginning the K2 era.

Just realized, my K2 has a Stanley Motorcycle sealed beam. I'm going to yank that baby out and use it in 576. Don't really care what's in my "rider" K2. :)

At CB750 shop manual, dated 69/11 page 151, i found the information that the Headlight is 12V-50/40W.

Should be this the correct Stanley Sealed Beam Headlight for Sandcasts?

There was a time in the mid 1980s ( I owned a Honda dealership at the time) that when you ordered the headlight replacement part number 33321-505-003
American Honda would send a GE # 5006 automotive sealed beam. They did not even bother to take it out of the GE package.  Of course no CB750 ever left the factory with this bulb.
I've seen the future, I can't afford it.

I noticed that are two types of KOITO headlights.

The early type was the K0/K1/K2 model headlight, part number 33321-505-003 and 33100-300-673 for the assembly part number.





The part number 33321-505-003 was used on S600 Honda car on Headlight (LH). See Honda S600 parts lists attached below.

http://www.cmsnl.com/products/light-assyrightfront-winker_33400505610/

Below you can see a S600 with a Koito headlight, note the "2" (in red).



The later type was the K3 onward model headlight, part number 33321-341-701 and 33100-341-701 for the assembly part number.



Please, correct me if I am wrong.

What is the correct Stanley headlight for sandcasts, with or without the center logo?

Thanks.

Marcello

imho, this is the head light of choice  for any sandcast.  IMHO.

I need to say up front that I really don't know which is correct, however I don't believe the #2 on the top front glass should be considered a correct replacement headlight. IMHO it is incorrect KP

Ditto that.   

also, i cannot quit believing the Stanley "motorcycle" headlight is correct for sandcasts.  Andy Dixon's very original unmolested 2 owner #175 has a Stanley headlight.
