I used these for a Bachmann JS observation car and a Bachmann caboose. Substituted LEDs for the bulbs that come with them. One thing to note is that they are out of "scale" on the large side. At least with the Bachmann cars. Yes, that is a good price.
The prices on Ebay are some times crazy.
There are some pretty good deals.
Others "deals" can go the rather outrageous route with pricing that's so ridiculous it boggles the mind.
There's a New Bright set on Ebay right now that the seller has priced at $10,000.00.
