Why: When I load the rack with several bikes, they often obscure the car's tail lights and upper brake light. This project helps make the car more visible, at day and at night.
- This instructable assumes you have the electrical skills to wire trailer lights.
- This instructable assumes your car is already wired with connectors for trailer lights.
Caution: Please check your local laws to ensure this project is street-legal where you live.
Acknowledgement: This was not my idea. I saw one on the road. I was so impressed, I built my own.
Step 1: Parts and assembly
- Commercial trailer tail light assembly (I used an LED unit from Harbor Freight)
- Wire, shrink wrap, and connectors (from the trailer store)
- Wood, cable ties, string, goop glue, staples, paint (from the scap box)
- I cut a piece of wood to fit nicely on the bike rack.
- I attached the trailer light to the bottom of the wood two ways:
-- A glob of glue (Goop brand waterproof glue) between the light and wood
-- Two heavy cable ties (zip ties) around the light and wood
- I soldered a length of wire from the light to the trailer connectors.
- I stapled a length of string to each end of the wood.
- I painted it a visible color.
