If you need to reset the brake light on your Ford F150, there are a few steps you'll need to follow. First, locate the fuse box under the hood and find the fuse that corresponds to the brake lights. Once you've found this fuse, remove it and then reinsert it after about 30 seconds. This should reset the brake light. If it doesn't, then you may need to check the bulbs or wires leading to the brake light.
