Hi,
You Guys Helped Me With My Rearview Mirror Wires, So I Will Give U Another Shot. The "rear Lamp Failure" Warning Beeps When I Turn My Headlamps On, Even Though I Have Thoroughly Went Thru Every Bulb Back There, And Nothing Is Out. Does This Truck Have A Lamp Failure Sensor, Like Some Toyotas (which I Know From Experience Is A Costly Part) (i Sell Them). But Anyhows, Has Anyone Had This Same Problem, And What'd You Do To Fix It? If A $300 Sensor Will Fix It, Then I Will Live With It, Since I Know All The Bulbs Are Good, Just That Irritating Little Message On The Screen Is Drivin Me Nuts! Any Help At All Will Be So Appreciated! -thanks! (oh Yeah, If You Leave The Headlamps Alone, The Little Message Won't Come Up, Under Normal Brake Use)

ok well I had this problem also and so did 100 other ppl..lol. I checked my bulbs none of them seem to be out, I look at the side marker, side rear light, brake, reverse, none of them seem to be out, so then I remember about the License plate , I cehck nope they were good. couldn't figure it out. so I had a friend hold the BRAKES IN (AT NIGHT) while I checked the lights again, and it end up being one of the high mount stop lights in the liftgate, theres 3 bulbs and one of them was out. I would check there do it at night it is easier to c. and go thru each bulb carefully. also don't forget about the license plate light
