Hi everyone:

I and buddika made a ciruit for the fog light flash: we tried typeA and TypeB:
Type A:

Type B:

The type A is not working and the type B is still not work, so we tried to find where is the problem. we did not have too many time, so we focus on the type B, because we thought the type B is more suitable for the circuit.

The type B include two parts:

One the signal send:

One is the transistor and bulb:

we test the transistor and bulb, not working. and we thought how to test the signal 555.
