This listing is for a pair (2 bulbs) of daytime running lights for your c6 corvette.
The switchbacks are neat because they take on the normal amber color for the turn signal and daytime function but then they turn a crisp white with the parking and/or headlights on.
With the bulbs, I'm including a free pair of resistors which are needed to prevent the hyper flashing due to less resistance in LED's. Most competitors up-charge another $15 for the resistors.
Also note that these LED's will produce a cleaner, crisp white color in comparison to your factory yellowish low beams. I have matching low beam bulbs also available.
