Here's an update on my quest to find puddle lamp modules.
I had a good exchange with Torrie, thanks RockPick. And he came up with a part number. But, when I researched it, the number belongs to a flat rectangular assembly that can only be the turn signal module.
The most interesting thing is that in any "exploded" parts view, the puddle lamp is never shown (but the turn signal module is). I've decided the puddle lamp is just not used a whole lot in Fords and if you want one, you have to buy the mirror to match.
So, I got a bright idea last night and decided to research Lincoln Mark LT mirrors. They ALL have to have puddle lamps, right? Well, guess what? Their diagrams don't show puddle lamps either and there is no source for one in any of the online parts catalogs I know about.
My conclusion: If a puddle lamp fails and you want a replacement, you buy a new mirror assembly (about $200 each - but the left side costs more than the right). Of course, the puddle lamp is just a "show" item - suitable for impressing the ladies, but not much good for anything else.
Most of us would probably live without it.
And, I suspect, looking at the brightness of the thing, it is running at a reduced voltage to make it last longer than the truck. I suppose too, if one should actually fail, then there'd be no reason not to try to cut it open to replace the bulb.
Overall, I still think it's not a good example of customer-oriented engineering!
