Frist off, what I'd like to do is replace the incandescent bulbs in the outside mirror puddle lamps with LEDs. I suspect they are of the "festoon" type. But I have a problem.
For those of you who've never taken one out, here are three pictures of one of mine: The first is the lens side, you can see one of the two electrical tabs on the tight and the clip that holds it in the mirror housing on the left.
This is the backside. The round "sticker" is a coated paper stuck over a small hole in the capsule. My guess it it allows pressure to equalize between the outside and inside, while still supplying a bit of waterproofing. Inside the hole is the back of a reflector - there's no access to the bulb.
The third is simply the assembly on edge. The lens is sealed to the black back - it does not unscrew or "pop off".
I can't see any way to get into this thing except to cut the lens off the black backing, probably with a razor saw. And, you can't replace the bulb without "opening it".
And here's the real "kicker": According to my dealership, you cannot buy this llittle light assembly by itself! If you ever need to replace a puddle lamp, for any reason, you have to buy a whole new mirror!
The light is not stocked and I cannot find it anywhere on the internet. Superb, customer oriented, Ford engineering!
If I had a spare to "play" with, I'd cut one open in a heartbeat. Without the spare, I'm reluctant to try.
RockPick seemed to remember a post one time in the past from someone who had replaced his puddle lamps. I can't find it. Does anyone know where this is or does anyone have a clever idea to get this thing open that I haven't thought of?
Looking forward to any *helpful* replys! (I'm sure there'll be some of the "other" kind too).
