I have checked all connectors - all good but still no driving light, so i decided to install the old one again, but this now have the same issue. I have checked fuses and is now out of ideas 
Any suggestions? |
I've heard of folks disconnecting battery cables and that "reset" seems to help things. Go through the process of undoing battery cable, undoing tail light, hook up battery cable then taillight.
Be sure to follow proper battery cable protocol with reds and blacks and which you disconnect first.
It seems that your issue isn't specific to your taillights but could be electronic.
