to all,
i am planning to build a mini beacon light at front and back (if there is a space) and also build a small siren in front of bicycle together with a switch to control both siren and beacon light.
1st what type of battery should i put for the control of beacon light (the lighter the better)
2nd i would wish it is water proof in case of rain
3rd do you all mind to share some idea of circuit
thank you
