GU5.3/MR16 LED Bike Light

thingiverse

This is my custom-made bike light, utilizing a GU5.3/MR16 12v LED spotlight and a budget-friendly Li-po battery pack. I aimed to create a decent amount of illumination for cycling on dark cycle paths and decided I could use a 12v LED spot and some spare Li-po packs. You will need the following components: 1 x GU5.3/MR16 12v LED Spot (available at affordable prices from DIY stores - I found a 4.8w 350 lumen one at Sainsburys for just over £1) 1 x GU5.3/MR16 wire socket (available on eBay or Maplin) 1 x Battery - you can choose your preferred option, but I'm using a spare Turnigy 7.4v 2 cell 1Ah Li-po pack; initial tests indicate this pack will last over 2 hours. Some additional materials required include wire, sockets, heat shrink, and M4 nuts and bolts. Use what you have on hand to wire up the LED to suit your needs. Print the following components: 1 x Light Body 1 x Light Rim (Optional) 1 x Mount Arm Note: I've not tested the arm as the light body fits in place of the front reflector, using that arm instead. The LED was a tight fit, so I had to scrape some plastic off the edge of the LED and the housing. I've added extra clearance to the model for testing purposes. I glued the LED in place with super glue, followed by the light rim and more super glue around the edge. Time will tell if it can withstand knocks and bumps. Fit the light to the mounting arm and attach it to your bike!
