After market tailights incorrect wiring

Hello,

I had issues with tailight just solved issue but not sure if the light on back of cab above box is supposed to be tailight or brake light maybe both. It comes on with tailights.

This light turns on with brakes when tailights off, but dosent when tailights are on.

Thanks

 

The light on the back of the cab above the box is a 3rd brake light only and should not be on with the running lights.
Sounds like you may have some bad grounds causing gremlins.

 

Thanks,

yes just found the problem new tailights ground was messed up in pin connections.
