all the ones i've handled are chinese. i've not seen any japanese ones, nor
have I seen any reference to euopean manufd aftermarkets. these slotted
design ones are made by Eagle Eye.
note that the headlight you referenced uses smaller bulbs....using H1 instead
of H7. sometimes, to make the package smaller overall so that they can
advertise 'slim' etc (i'm guessing) they go with smaller projector, smaller bulb in
the process.
Performance Products seems to have high retail prices - i've never purchased
anything from them as a result. All things being equal, i have always found
alternate vendor to purchase and at much lower price.
