You must have preempted voltage from a source the rear light sensor used to determine bulb functionality. Undo what you did and the problem may be fixed. ;)

all i did was replace a burnt out bulb with the correct size and voltage replacement
No, when you installed your fog lights. Something happened when you replaced those. Maybe knocked something loose or caused a ground fault.

I suppose. However, when you've been working on cars as long as I have, you began to realize there's no such thing as a coincidence...... ;)

The LED bulbs aren't going to work..

The sensor works like this

It measures the voltage coming through the bulb. Your LED light bulbs have resistors in that bring the 12VDC down to something around 3-6. It sees the voltage drop. It says you have a light out..

hehe i figured out a rather simple shortcut to bypass the sensor.....ignore it by cutting the wire that goes to the idiot light...lol the sensor can scream at me all it wants...i won't hear it lol
