Hi! I have purchased components to control my truck light bar and would like to control the light bar via Arduino. I have a 4 channel relay module (Product Page) , a 2.3 TFT touch screen, and the light bar (Product Page). The light bar draws 10 amps/ 12V. Since this light bar has two functions, amber and white, I am going to independently power each one from the battery routed through a fuse box, which will use 2 channels in the relay module (one for amber and the other for white). This is my problem, the relay control can only handle 10 amps. Is this feasible to control this light bar? If there needs to be more information I'm sorry, I will add any other information needed!

...This is my problem, the relay control can only handle 10 amps.
If the light bar is 10 Amps and the relay can handle 10 Amps, what's the problem?
(Your link to the relay module doesn't work.)
Thanks, I updated the link!
Since this is going to be in the cab of the truck, I don't want it overheating or catching fire. I know it can handle it, but shouldn't I be using a larger relay especially if the lights are on for longer periods of time? The relay harness that comes with the light bar has 40 amp relays, so my mentality is I should be using that relay.

So why are you not?
