can these light be wired to turn on as a regular light bar & separate button to turn corner lights? i did not want to have so many remotes. i was also purchasing 4d led strobe light bar to work with this light bar

hi, the wireless remote has separate button to control corner lights and middle main leds, you don't need more remote

Power source? Battery or wired to car?

Hi, thank you for your question. All lights are wired to car to get power.
