It is a proportioning valve for the Bosch brake system, part # 18020180.

I probably need a anti-flicker decoder for my GMC truck. It has lights that automatically come on when it's dark outside. when you turn the key on. Since I installed LED bulbs in it, the lights flicker while the engine is cranking over. They do stop flickering after the engine stops so it's not a real problem. It just looks odd when they flicker while cranking the engine. I didn't know they made a device like this to cure the flicker problem.

Because I didn't want to cut and ground one of the headlight wires as mentioned in previous threads, I bought the H4 9003 Canbus Decoder (noted above) and installed one of them to the drivers side LED headlight harness. I didn't have to install the other one to the passenger side since the current harness for this side is actually a spur from the main headlight harness. The decoders do come as a pair, so I now have an extra. The LED headlights now go up and down as they are supposed to. Yea!! I want to thank everyone for your help and guidance.
