Abstract : Our project is developed in such a way that it detects light intensity and automatically switches to low beam or high beam accordingly using a LDR and another thing is automatic wiper as servo motors which works automatically on detecting rain drops and alert system to alert people during accident by sending SMS to saved phone numbers and rechargeable batteries are used to power the whole system making our project energy efficient.

Keywords : LDR, Automatic Headlight, Rechargeable Battery, Automatic Wiper, Alert System
