Will a 9005 bulb fit a H11?
No. Despite having a similar design (same L-shape, same plug design), H11 and 9005 bulbs have different bases and locking tabs, making them incompatible.
How can you tell the difference between 9005 and 9006 bulbs?
The 9005 is the High Beam and the 9006 is the Low Beam. You’ll need both of them for your car.
