Thank you for writing to me about bulb h7 vs h11.

Frankly speaking, bulb h7 is very different from h11.

For example, h7 bulb is PX26D, but h11 is PGJ19-2.

In order to make you clearly bulb h7 vs h11, I will show you pictures as below.

Because we are manufacturer, bulb h7 and h11 are cheaper price.

All of our h7 bulb and h11 have halogen, led and hid.

Hope you come to talk with us bulb h7 vs h11 at any time.
