<p>This is a rather simplified bike light design. I ordered on of this MR16 12V DC LED spots with 15 Watts from Ali Express: <a href="https://de.aliexpress.com/item/32809806189.html">https://de.aliexpress.com/item/32809806189.html</a></p> <p>Pay attention to get the warm white version since this makes spotting objects in the forest under wet conditions much easier.</p> <p>I printed my ring in 100% infill with PLA. This might not be strong enough but time will tell. I simply soldered two wires to the end connections of the spot. The spot itself is hold in place simply by using hot glue. The MR16 DC LED spots will most likely work with any Li-Io type of battery ranging from 3s to 4s.</p> <p>I power mine straight from the e-bike battery using a DC-DC stepdown converter. Check out my half-encasing for stepdown converters.</p> Category: Vehicles
