These are the type of lights you see on kiddy rides, some arcade games and fairground rides. This type is a simple 12V fixed colour variant, except for the RGB colour changing variant.

Most high profile modern rides use something similar, but with a 24V addressable system for chasing colour effects. But these ones are better suited to cheaper and simpler applications.

The reason the RGB colour changing version is so bad is because it is using colour changing LEDs in series. That would work with the slow colour transition type as they always pass current by alternating between colours during the pulse width modulation dimming. But with the fast flash type that goes through a strobing sequence it limits the current to the other LEDs. It's an interesting visual effect, but does mean that it spends a lot of time flickering dimly.

These lights would be OK for fun personal projects or even some designer off-grid lighting. But I wouldn't recommend their use in bulk on a ride. The better quality ones are fairly cheap when bought in bulk for applications like that.

Here's the AliExpress (not a sponsor) listing for these lights:-
