For your consideration, here is a lot of 9 Number 5F Push-In Replacement Bulbs, 12v, from Renown, made in Japan, for Christmas light strings. This is new old stock and comes with the packaging, except for two. The packaging has very little wear on it. Item pictured is the actual item up for sale and come from a non-smoking household. (52.130c-.7hc)

There are two packages and two loose bulbs. Here are the details:

1. No. 5F/50, Package of 5 Multi-Color for set no. 5c/30/3F-SC/50/5F. I do not think these are the flashing type.

2. No. 5F/50F, Package of 2 Clear Flasher for set no. 5c/30/3F-SC/50/5F and 2012.

3. 2 loose Red bulbs. There are two wires at the base of both of these, not sure if they work or not.
