Something to consider
Using LED's as a light source for backing up, may not provide the light expected. LED's seem bright when you look directly at them (good for running lights & brake lights), but they don't seem to light up objects very well.
Before committing to LED's, for backup lights, try both LED & incandescent bulbs, measure the reflected light coming off your garage door, for each type of light. The light that produces more reflected light will be much better (safer) when looking in your mirrors and backing up.
The same holds true for camp lights.
