Sure, the car didn't come with upper brake light. In EU it became obligatory for cars manufactured from certain year (I don't remember) after the mine was. It is not obligatory for cars manufactured before (the mine), anyway I would like to fit it because of its evident utility.

OK I don´t know US law about it, in EU actually most cars are equiped with upper brake light, in spoiler or in rear glass. What I want is to install an S40/S70 interior upper tail brake light in my 850 (supposed easy, the unique problem is to fix it in the correct position, the rest is a simple question solved with a wire correctly connected).

And I would like to get advice about led lights versus bulb lights.
