15 amp fuse blown....replace with 20 amp???

Here is the deal. I just put on the DRC tail light and blinkers all around. I also bought the customLED relay. It works for a few minuets, then the fuse blows out.  Is there a way I can use a 20 Amp fuse in the place of the 15 Amp to support the extra weight of lights and have no issues?

Thanks a lot.

Those led lights dont use many amps at all you dont need a bigger fuse you have other issues.
Check your wires for bare spots and bad connections.

Yeah, there's no way your lights are drawing more than 15 amps. As mentioned above, you probably have a short or an exposed wire touching the frame somewhere.

Definitely don't put a bigger amp fuse thats how fires are started. like stated above probably have a short.
