LED Bike Helmet

Step 5 Affix LEDs and wires with conductive epoxy

Mix the conductive epoxy and attach LEDs and wires to the paint traces. Since the helmet is not a flat surface and I wanted to attach everything at once, I used a large piece of tape to gently provide support to the LEDs while the epoxy dried. Once it's dry (or mostly dry), test your circuit to make sure the LEDs light up. If they don't, you may just need to let it dry more. Let everything dry for 24 hours, then use some more 5-minute epoxy to reinforce the conductive epoxy and seal around the bottoms of the LEDs (for waterproofing and extra strength).
