Bike rack brake light holders

thingiverse

I found that my hitch mounted bike rack made it hard to see my tail lights once I had my bike on it; So I made these tube end caps that hold a 3/4" LED trailer light and allow me to hook up to vehicle trailer wiring. I made these for the Harbor Freight HaulMaster #63924 carrier but should work with little modification for any bike rack that uses 1" or 25MM tube for the support arms. I also bought these to finish up the project: * LED Resistor kit (2 Ea.) Allows one wire lights to act 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" mini sealed LED (2 Ea.) http://optronicsinc.com/PRODUCTS/LEDLighting/LEDMarkerClearance/Products.aspx?SeriesID=457&ProductID=259 * 4 Pin flat extension cable (1 Ea.) end 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 1/4" split loom to protect wiring.
