Light bars

Hopefully someone will be able to help me here. I have a large light bar and 2 smaller ones either side of the large one. Once I wired up the 2 smaller ones the whole top row now don't work. I have em through a relay which used to run 4 spotlights fine. Do I need to install a larger relay because I thought the led lights took up less power?

all depends how you have wired it up, have you got the polarity wrong?

Did you wire it up in series or in parallel?
