l have a 1995 205 n l need to find 1 left headlight and 1 right tail light and the 306 looks extremely similar to my 205, any help is welcome and appreciated.

Absolutely NOT the same. Especially the tail lights. l will include a photo of both for u here. (you may?? use head lights from a 309, l am not sureabout the tail lights, but same time period for Peugeots)

The headlights of a 205 will fit all 205 is between 1983 & 1998. but the 306 was made from 1993 - 2002? & the body, lights, bonnet shape r very different.

PS: be careful about buying a headlight from a 205 years 83-87. They take a fat round lamp. 87-98 take a long narrow lamp.
A very concerned 205 owner will see the difference in glass rib patterns on the FOUR different manufacturers of 205 headlights (Valeo, Infasa, Seima & ??forget) . And some lights have the small running/city light on the right, some on the left, inside the big light.
