The brake lights work correctly when light pressure is applied to the pedal, but then goes out when more pressure is applied. We've checked the fuses, bulbs, and replaced the brake light switch and relay. What else could cause this issue?

    Thanks for the help guys. As it turns out it was a combination of two things. There was a shorted out wire AND the brake light switch that we had replaced was bad. We repaired the wire, and got another switch. Thankfully it's working perfectly. I never would have thought that a brand new switch would be bad. What are the odds of that?
