In-car lighting

friends, I have 206 vehicles, I want to light up the interior of the rear seat or somewhere in the back so as not to spoil the originality, how can I do?

I think it is enough to plug in one strong white led for ceiling lighting. You don't need to pierce the right or left of the car or get a cable.

As you said in the 307s, there are both at the back and the back, take it from the lighting, cut the ceiling, draw the cable from the ceiling to the back of the lighting, and if you want an original look, take another one from your car's ceiling lamp and apply it in a beautiful way.
