"Yaris" fog lights vs OEM fog lights

My passenger side fog light lens took some kind of serious hit sometime recently & shattered in the middle leaving a 1" hole . I decided to splurge & buy an OEM replacement - I had installed the "Yaris" kit a few months ago. The new unit came yesterday & I got it installed last night.

First, the OEM unit has a glass lens, the Yaris fog light lenses are plastic. The OEM unit is noticeably clearer when compared to the Yaris, which means more light from the OEM unit. The reflector geometry looks the same between the two, and the outer housing looks identical. The OEM unit is made in Belgium (??).

I bought Silverlight H11 bulbs for both sides, and discovered that the Yaris wire harness connectors don't fit the new bulbs properly. The connectors won't lock onto the bulbs & appear to be a bit too long. After fighting with the problem in near-darkness last night, I grabbed some electrical tape and wound some around the connector & bulb base to keep the connector secured. I suspect the original, low-cost bulbs & connectors in the Yaris kit came from the same Chinese source, and that company didn't quite succeed in copying someone else's connector design.

 

Correction: my old, Yaris fog light lens IS glass, not plastic. I pulled it out of the trash and examined it more closely. What made me think plastic was the lack of sharp edges around the shatter point and comparing the weight/heft of the Yaris light vs the OEM light - the Yaris light weighs significantly less. So the glass on the Yaris light is either thinner or a different grade of glass. It is less transmissive.

As far as the relative lifetime of the two fog lights, that will be an experiment. The first Yaris light lasted about six months, which disappoints me.

I also played with the alignment mechanism on the broken light. The reflector rocks up and down, not the bulb. I've found these to be challenging to align to any degree of accuracy, so I'd recommend that before installing the housings, take the bulb out and look into the front, checking to see if the hole in the reflector is centered on the bulb mount. That at least ensures that the lights point straight forward.
