Opening your garage door with your light switch: Difference between revisions

This mod will enable you to open your garage door remotely, just like you do in a car. These instructions will allow you to open or close the garage door just by flicking the low beam (if you're one of those people who always rides with the high beam on). You can also wire it for the  low beam,  the horn, or an accessory switch.  This works well for people who don't want something in their pockets in case of a fall, don't like the look of an opener duct taped to the bars, or often forget to bring their remote with them.   

Here is the business end of the mod. It is nothing more than an opener and a 12 volt low amp [[How do relays work?|relay]]. When the light button is pressed down, it closes a circuit between two plates, which triggers the door. A wire is soldered to each plate, and the wires are routed through a relay, which turns on when a 12v current is passed through the incoming wires. These incoming wires are tapped into the high beam in this case.  

As for wiring the relays, you may have to solder them, or some may use crimp connectors. The back of the relay box should contain information about the circuits and connection points.
