We are currently upgrading our M4-60 signal tower light.
We modified the circuit and added a DIP switch.
Customers can adjust the sound and flash functions by themselves.
The following functions can be converted by the DIP switch:
1. Flash light or Steady light.
2. Continuous sound or intermittent.
3. Large volume or small volume
Moreover, the modules can be arbitrarily added or replaced.
(Such a design will reduce the inventory of the distributor.
More importantly, we maintain our price advantage.
If you are interest in this product, please feel free to contact us.
