Homemade Halogen Bike Light

Step 5 Bulb Wiring

An old halogen bulb holder was used. This one has separate screws for wires to fed inside. The tiny grub screws are to tighten the bulb into the holder. I used a random push switch and a phono (RCA) socket for the battery cable connection and those were fixed in a extended pipe cap as shown in pic. All was soldered and then insulated with electrical tape. Pretty bodge!
