I'm pretty sure I had a US style plastic Fire Chief Helmet like this when I was a kid. It was great fun to wear.
About ten years ago I very nearly bought an illuminated version of it still in its box in a discount store full of 80's toys. The box was window faded so I didn't bother. Maybe I should have.
The helmet and light looked like this one on You Tube
I was amazed to see that the toy in this clip was by Radio Shack. I associate them with radio-controlled vehicles and not general toys like this.
Did you have a fire helmet as a youngster readers?
