10 15watt coloured party lights and 21 spare bulbs (Kentwood RG31)

These are old school, incandescent bulbs rather than led. However for occasional use, you might disregard the power consumption.
I stocked up on spare 15watt pigmy bulbs when they became difficult to get hold of. Every time I got the lights out a bulb needs replacing. I see that the two red ones are dead when I got them out for the photo. These are almost antique, they must be 40 years old.
