    i have searched as long as i could stand with no success...

    i have a 2005 TRD 4WD OR with tow package.

    both of my brake lights are NOT lighting up when brake pedal is pressed. the third brake light on the cab DOES light when pedal is pressed.

    first i checked the fuse - it was good.

    then i checked the bulbs - both good.

    WTF???

    no other symptoms.

    any ideas?

    i did not install new bulbs. they sure look good though. i can see that both filaments are still there and connected. hmmm. let me run to the store and get some bulbs and try that.

    seems strange both are out though?

    :) To start on a process to solve this problem, you need to buy a cheap test light. Go to Harbor freight and get a 3 or 4 buck test light and remove your bulbs, have someone push down on the brakes and make the lights work. Use your test light to see if it will light when inserted into the socket to check the terminals. If they light up, then your bulbs are bad. If the test light does not light up then we have a power problem. You also need to check for power to your trailer plug to see if will light up with the test light and the brake pedal depressed. If it does light up and the main sockets don't then you have a bad socket or a bad ground.
    You have some relays that control your brake lighting and your trailer lights. If you have VSC on your truck, then you have a relay that powers the brake lights though that relay. You also have a towing tail relay under the dash and you have #18 relay under the hood that controls trailer towing tail.
    This should give you homework to see if it helps. Good Luck.

    Sometimes the issues that seem the hardest, have the most simple answer.
