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.

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.
