Installing Backup Lights
I'm installing 18w LED backup lights that run 1.5 amps each for a total of 3amps. 14ga wire a distance of 30 feet. Do I need a relay?

To me...
A correct back up light issues an extremely wide light pattern which is hard to get without a dispersion lens with LED. Look again at outdoor floodlight with LED chip. What I see above are automotive lamps.

This is a true flood lamp. I would angle them slightly splayed toward the outside. No you cannot read a newspaper at 100 yards but they are about 10 times as bright as any car backup lamp. Do not mount with cord facing up.
