"A brilliant detail in the HazStar is that it’s rechargeable, so as long as you have engine power, you can’t get caught out. It has a red hazard light that shines in the traditional triangle shape to let other drivers know you’re broken down, and can also work as a regular work light to brighten an area whilst you check on your car. I would feel much safer knowing this work light was in my car’s box of emergency supplies."
