Side industry lens headlights

Hello everyone. I bought a 2006 model 1.6 hdi comfort vehicle. But one of the ten headlights, the sub-industry headlights have changed. Naturally, the other is a little faded. I say if I change the other one of the sub-industry headlights. However, I do not know how to use lenses of sub-industry headlights. In other words, it reflects the light from a single point, or reflects it by distributing it like a normal headlight. I have been unstable, without the sub-industry, I will try to find the exiting headlight similar to the pale original one. I wonder if anyone has an idea or experience on this

First of all, welcome to us. Do not deal with any sub-industry, I recommend you to find a clean original.

Thank you, thank you, both for your kindness and your answer.
