Need advice to improve low-light focusing technique

I found a solution by experimenting but it is not for this kind of pictures.

When the AF begins to not work well due to the lack of light I have a small red laser not to strong but strong enough for the job. I point it to where I want and the AF locks fast on that point.

Maybe this will be useful to you on other situations.
