[providence]

Hi all,
After getting my fingers almost chewed-off while uncovering the back plate of the light housing and successfully removing the OEM bulb from its socket, I noticed that the plug is totally different between the bulbs; OE has 3 small (male) projections while the LUX H8 had only 2 (larger) prongs.
Also there seems to be a completely different housing between the two products; OE is square while replacements have rounded edges.
I'm sure nothing got broken while carefully maneuvering through the removal steps.
Is there an adopter that I just didn't get or did I get the wrong part/bulb?

See pics to for illustration:

Thanks in advance for the advice.
