What if your car breaks down on the road in the nights? What if you need to get it fixed without enough lights?
Do you have to hold the flashlight and spanner in each hand? Don't you think that is inconvenient?
This design of spanner will be in the help of these problems. We combine the spanner and the flashlight perfectly, which frees your another hand, so you can do the repairment more frequently and more effectively.
The switch of the light can be open while texting the pressure. It is really easy .
