Chevy led lights
 

So my 2002 Chevy Silverado 1500....

I have added 2 LED light bars for brake lights turn lights and running lights...

When my headlights turn on I have running lights on my light bars but no brake lights or turn signals on the lightbar's..

If I turn my headlights off then I have turned signals and brake lights on the light bars.

My normal lights on the rear of my truck work as should
just having issues with the lightbars not working as should

Again if headlights are on my normal taillights work just fine but my LED light bars don't work correctly

I hope this all makes sense due to I'm new to the whole truck forum thing

Did it cost you a lot of money?
