Lionel Carousel 6-14109 Bulb Replacement

@dkdkrd  Sorry you haven't gotten any replies yet.  I may be helpful if you were to provide more information besides the Lionel cs-6302998300-p part number for the bulb.  Looking at the picture of the bulb at this link, I see why it's called a fuse bulb, as the case looks similar to a small glass fuse.  Since these types of fuses come in different case sizes, it's unclear which size these carousel bulbs are.

What are the measurements of the bulb case?

Are there any identifying numbers or other information on the case of these original incandescent fuse bulbs?

Steve....

Thanks for thread resuscitation...

They're called festoon bulbs...or fuse bulbs.  The carousel bulb (6v) measures 6mm diameter, 28-29 mm long.

Since the original posting, my wife found a pair of what appears to be the correct bulbs (not identified for this Lionel accessory, though) on Ebay...and ordered them.  Should be here by the end of next week...so they say.  May not be the end of the story...and certainly not if these bulbs, in this application, are prone to early demise.  (The motion and sounds are really cool!  The lighting?...maybe not so much...incandescently speaking.)

OTOH, what seems to be potential replacements are LED versions of these bulbs.  These are much more plentiful on today's market...Amazon, Ebay, mfr direct, etc., etc...but I'm not sure of their compatibility  with the 3-bulb series circuitry in the accessory.  It's not clear from the descriptions and I'm not into trial-and-smoke adventures towards things electrical.  Too many X-spurts I value on the Forum.

Thanks for your consideration!

KD, thank you for the physical dimensions.  I believe the information stamped into the original bulbs' metal end sleeves would also be helpful in identifying suitable aftermarket replacements.

But of course...if there were any such markings.

Zip, nada, zilch, nothing...not never nohow.  Confirmed by spouse and when using my Opti-Visor (I'm 20/25 after the cataract operation, per the opthalmologist, but at 78 years I concede any and all possible deteriorations of senses.)

The only clue to the proper replacement started with the Lionel part number stated in the accessory owner's manual.  From there I had to Google around with that number to find someone somewhere who had correlated it to a mfrs stock/type number.  Even then I had a short list of possibilities that showed (1) incandescent replacements were in a price category currently including eggs, (2) incandescent replacements were really scarce, and (3) the 'webiverse' kept suggesting that my solution was better served looking for the LED version...whatever that is re this accessory.

So, here we are....

KD, I just sent you an email with an eBay link that may be of interest to you, a package of 10 incandescent bulbs for $10.

As far as using LED replacements, the 12V (AC compatible) LED replacements may still work fine at 6V.  If not, I'm unaware of how they could do any damage to the carousel or it's circuitry.  They should draw significantly less current than the incandescents.

I believe that the worst case scenario is that they simply wouldn't illuminate and you'd possibly be out the cost of those LED bulbs.
