Default Different fuse capacity.

My 15wat pwraccuracy fuse always goes out when I use my LED fog lights, it's happened twice now and I don't even know if that's the source but this is where I started.. Is it possible to use a 20 watt and see if it holds or would that not even light up.

Do not just up wattage of a fuse. The fuse is there to protect the wiring of the car. If you're blowing fuses, then something is wrong or your trying to draw too much current through the wiring from what you added.

LED fog lights should use a lot less power; so it sounds like something is bad with those.

If they do require more current than 15A, then wire in a relay that draws power from the battery, then use the fog light wire to trigger the relay. BUT make sure the power lead from the battery is fused as well.

what he said except its 15 AMP not watt, you don't up the wattage of a fuse you up the amperage. but NO you should never replace a fuse with a higher rated one especially if you keep blowing them.

Not to mention that your fog lights should not be on the PWR ACCY fuse anyway. The fog lights (when properly wired) are on the running/parking light circuit protected by the TAIL LPS fuse.

I say why not use a bigger fuse? If that blows too, wrap it in aluminum foil and plug it in again. Then get some marshmallows and toast them over the resulting bonfire.

D'oh! 10 hours sleep over the last 72+ hours, and not enough coffee/Monster/5-Hour energy when I wrote that response. Brain processed it as Amps, but even I regurgitated Watts.

Hmm, I will try to relay it correctly. Would of never guessed that, thanks.

If you have LED lights (not HID) and they are blowing a fuse then adding a relay will only make the problem worse. LEDs draw far less current than standard bulbs so they are LESS likely to blow fuses unless there is something wrong with the wiring. You will be feeding more current through the relay to a circuit that apparently has a dead short. You should do some testing and find the reason for the blown fuses before you start throwing parts at it.
