L.E.D. Lights - long lead wires

Many, many threads on this topic - most recently (that I've seen) is this one. There are several links to LED sources within the thread.

Perhaps someone can correct me on this, but last year I was told one could buy new LED bulbs that would fit into existing fixtures. No need to re-wire/install new fixtures. If this is the case, I plan on changing the reading lights in BR and several lights in main body of coach to LEDs.

I used these:
eBay LED lamps

I'm happy with the color, but you can get similar in warm, cool, and maybe blue.

The leads are a little long, but that's because they come with different socket adapters, and also insures the leads will be long enough for any fixture. I just curled up the excess.

The ones I bought came with double sided tape, and I just stuck the boards against the fixture reflector plate. So far the tape is holding, but I doubt it will last forever. I figure I will just put a plastic wire tie around them if needed someday.

Sorry, did not shoot a pic of these.
