Lights aren’t blue here, they’re still warmer than the rest of the frame, which is very cool in temp. They look neutral white here at best in film that’s really shifted towards blue overall. If they were blue they would look VERY blue here.
It’s also possible since the lights are the brightest light source here the white balance is based on them, which are yellow/warm, which is shifting the whole frame blue and making them look neutral white. If the lights were the source of the white balance in these frames and they were blue then the rest of the frame would most likely look neutral or warm by comparison.
Hot Toys has no track record of finding obscure secret details and a long track record of getting things wrong bc of a lack of attention to detail or general carelessness.
There’s about a 1/5,000,000,000 chance there’s some secret stunt car with blue lights that was never photographed or filmed that Hot Toys had access to and a 99.9/100 chance they just had any easy source of cheap blue LEDs and they went with that.
