wall lighting

Wall light on strike
A few days ago it happened
I thought it was the bulb
Changed it yet nothing came to light

I brought the wall lighting set
To the repair shop hopefully get a spare part
The electrical technician broke the connection
Inspite of I told him there were two screws to remove

So I took it back
A lost cause hanging on the wall
Rain or shine the electrical line isolated
It feels safe for the other wall lightings

Today I bought a new one
Thinking it could help
Nay there is no light too
So my final countdown
The electrical wire got shot
Now it is beyond my ability
DIY only at the fixing bulbs
Maybe some wiring connections
And I wasted money
Buying a new set wall light
