A3 LED headlights
 

Hi, I got a A3 2012 without the LED headlights, I would like to upgrade the headlights similar to the one in the A4, when I look the front of a A4 and A3 they are very much the same. I wonder if they fit in the A3, anybody have an idea

definitely not. Some people pulled the LEDs off the A4's lights and inserted it into their A3 lights. Others went with the non OEM lookalikes.

Thanks for your answer, do you have any idea where I can find headlight like non OEM lookalikes, or something similar?

you can find them on ebay, but the LED's are nowhere nearly as bright as the OEM ones. there is someone on the forums who bought the a4 lights and then took out the insides to put them into his a3, but it was a pretty complicated mod.
