So I purchased a aftermarket LED 3rd brake light for my truck and when I went to plug it in and screw it own the light was on but my truck wasn't turned on ,so i was thinking ok maby my dim switch is on or my door is open . Sony turned both the dim switch off and closed the door and it still was on and won't turn off anyone know why it stays on when the truck is off and how can I fix that .

 

Truck info? What aftermarket light did you get?

 

Even if your truck is off, when you tap the brake pedal, the brake lights will light. Do your other brake lights come on too?

The truck is a 2001 Dodge Ram 1500 2 wyd with a 5.2 and no nun of the other brake lights stay on and the actual center light doesn't come on unless I hit the brake just the lights on the 3rd brake light

 

So you're saying that it's the clear/white cargo lights that are on?

 

Yes those stay on even when the truck is turned
Off , I made shire all switches where off white / clear cargo lights still remain turned on at all times

 

Turn the headlight switch, and they will turn off.

 

Nope , they still stay on when the headlight switch is off the white /clear led cargo lights stay on doesn't matter if the head light or cargo switch is off doesn't matter if the truck is off it stays on ,I actually even turned the truck off turned the switches off and left it like that for a few hours to see if it would eventually turn off and never did

 

Then you have something wired wrong.

Keep in mind, the headlight switch controls the ground for the cargo lamp.

 

There was know wiring needed when installling the light it just plugged right into the stock connector
