I'm wanting to fit white LED strips under my doors, and mirrors, so when the door is unlocked and opened there is white under door lighting if you know what I mean? Now I spotted a power feed under the door as there is already a standard light under the door. But for under the mirror, I'd have to drill a tiny hole and feed the wire up and in the mirror housing and into the door, is the nearest power feed going to be the same under door light? Also I've not checked yet, but do these work by the door being opened? Or do they work same as interior lights I.e when cars unlocked do they light automatically? Cheers in advance!
