Fog light questions 2014 Tacoma regular cab.

Trying to set up some aftermarket fog lights on my 2014 taco. How do I find out how many amps my fog lights Will be using. Also I wanted them to shut on and off with the ignition so I currently have them on a " add a circuit" tapped into the headlights so 2 10 amp fueses. Will this cause the lights to draw to much power? It didn't blow a fuse but I'm want to be sure it won't cause a problem later. Thanks in advance.

 

If I recall, I put a 7.5 amp fuse in for them

 

An H11 bulb (common fog light bulb) draws about 4.25a at 12VDC. Two would be 8.5a. You generally want to fuse at 125% of the maximum amp draw so that would put it at a 9.5a fuse, so 10a. I would probably just use a 15a fuse (next size up) as that wouldn't cause any issues.

The lights will draw what they draw regardless of the fuse size you install. If the fuse is too small for the amperage, it will fail; if it is too large it may not fail when it should.
