Back up / Flood Lights

I have them on my Ford F-350 Headache Rack. I have them tilted down slightly inorder to light up the truck bed, trailer, side of the truck on the right and left. They help when backing up to off load or hook up to trailers. Because they may face the on coming traffic I really dont want to blind the other drivers. These lights are a good choice.

I am a Christian disaster relief volunteer and these lights help me work at night safer.

I do recommend them for disaster relief work.

Photos taken at night. 8MP camera, The camera would not see anything unless the flood lights were on.
