Bike rack brake light holders

thingiverse

I found that my hitch mounted bike rack made it difficult to see my tail lights once I had my bike attached; so I created these tube end caps that hold a 3/4 inch LED trailer light and allow me to hook up to vehicle trailer wiring. I designed these for the Harbor Freight HaulMaster #63924 carrier but they should work with minimal modification for any bike rack that uses one inch or twenty-five millimeter tube for the support arms. I also purchased these items to complete the project: * LED Resistor kit (2 Ea.) - enables one wire lights to function as both tail lights and brake lights https://www.bikebandit.com/aftermarket-parts/electrical/tail-lights/gyb-products-stopper-l-e-d-resistor-kit/p/15229?b=32414&CRTP=psc&gclid=CLGiq-q64OICFSAerQYd374D1A * Optronics 3/4 inch mini sealed LED (2 Ea.) http://optronicsinc.com/PRODUCTS/LEDLighting/LEDMarkerClearance/Products.aspx?SeriesID=457&ProductID=259 * Four Pin flat extension cable (1 Ea.) - will be cut off so you can wire to the lights and have a clean interface with the car https://www.uhaul.com/MovingSupplies/Wiring-Lights/Trailer-Wiring-Lights/4-Way-Flat-Wiring-Car-and-Trailer-ends/?id=4790 * Wire, Butt splices, and one quarter inch split loom to protect wiring.
