206 headlight replacement

Hello, I will change the headlights of my 206 1.4hdi 2006 model feline vehicle, front and back, but I do not have much information, about 2.500 leds on the Internet, are they useful or should I proceed from the original? Can you help me (it also says manual adjustment on the Internet, what is the difference in the headlights) thanks in advance

these days, Iranian headlights and taillights are popular

Where can we get it cheap? And how about we get xenon headlights?

First of all, thank you for your answer, I think the Iranian headlights look nice, let's see, I will go to the headlights during the week..
