I'm trying to remember the name of a kids TV show I saw in the early 1980's. It was shown in the UK probably on the BBC but may have been channel 3.
The story was this: a kid gets a laser as a gift (I know, it makes as much sense as Donald Trump's hair!) and uses it to solve mysteries and if I recall correctly rescue some kidnapped kids. The laser is basically a neon light in a wooden box that the kid carries on a shoulder strap. It can zap people and freeze them and it talks to the kid. The final scene was a heartbreaker. While the kid is sleeping the laser announces it has run out of power and will turn itself off forever. Before it dies it draws a heart in the air.
This was not a British show. I clearly recall that it was dubbed. Can anyone tell me the title or point me to some information about it please? Thank you.
