Hi Reinaldo, I apologize for not reading your post carefully enough to see you are dealing with pop-up headlights. I would check with your buddy on the "why" of this project -- knowing this could totally change your approach to this project, and possibly make your job a lot easier. You never know, he might want to use this headlight capability for hunting night crawlers or something. There could be a thousand reasons why he would want to do this to his headlights.
