I am getting an indicatorlight that says "Lamp Out" on my dash (right under the odometer and above the "Tow/Haul" indicator). I checked all around my truck and do not see any lamps not working. Any idea what it may be?

 

One the rear tail lamp assy is shorting out. Be sure to ck all lites on and the brake applyed too. may have a burnt out bulb or circuit board.

 

You need to fill out a vehicle profile and let us know what your driving?
At master tech said, it will probably bea bulb in one of your rear tailingt clusters.
If not a bulb, then a connection on the circuit board to the bulb has oxidised and is causing a higher resistance.
Clean all the bulb contacts out with WD40 and clean up you bulb bases.
reinstal and see what happens.
I put a small blob of high temp silicone on the bulb and connector when reinstalling mine.
This stops the bulb wiggling loose.
I haven't had a problem since doing all this and I used to get the dreaded bulb out warning and chime a lot.
Hope this helps?

LIke the guys noted check your stop lights. I got mine 2x in 1 week, it was the same bulb on the same board. It ended up the board being bad. I replaced the board and used silicone prior to inserting the bulbs into the sockets. I have not had a problem since. When you look at it, check the base of the bulb and not just the filament, it may give you a better idea of what may be wrong with it.
Good luck

 

Have the same issue...where's the board located?

 

Highline

The board is the white section located inside the lense of brake and rear lights. The board is where the bulbs are inserted into (I think it holds 3 bulbs). My advise is becareful removing the rear lense, it is kind of tricky but it can be done. Also, becareful in aligning the lense back against the truck when you are done.

 

try your third brake light up on the cab it's probally in there
