Product questions
Before you order
What is different about the rear-facing light?
It adds a rear-facing turn-signal and parking-light function with its own extended harness. Follow the exact connection diagram rather than leaving that connector unidentified.
Is the price for a pair?
No. Each selection supplies one assembly for the driver or passenger side. Order both sides separately if you need a pair.
