| Headlight Reminder | ||||||||||||||
| I built this device after I lost the timer. I built the circuit on the back of a Mallory Sonalert audible warning device. It is a simple relay circuit that senses when the ignition is on. If there is voltage to the NC contacts (which are held open when ignition is on) the sonalert will sound as it has the NC contacts connected to the headlight switch. I realize I could have bought one down at the auto parts store, but where's the fun in that? | ||||||||||||||
