Versatile emergency lamp.

versatile emergency lamp that can be operated in two modes (flasher and dimmer). The circuit is based on the dual op-amp IC LM358.The dimmer and flasher mode can be selected by using the switch S1.

Notes.

* F1 should be a 2A fuse.
* L1 can be a 12V; 2A incandescent lamp.
* IC1 must be mounted on a holder.
* The circuit can be assembled on a Vero board.
* Use a 12V battery for powering the circuit.
* A heatsink must be fitted on transistor T2.
* S2 can be used as an ON/OFF switch.
