Some posted here are h11 bulbs and some are h9 bulbs.
One is not like the other.
It's why I suggested getting a pair of them.
So do we know which is correct, h9 or h11?
The bulbs are not really interchangeable, one of the metal tabs and the socket needs tweeked pretty hard on an h11 to fit an h9 socket that's to the lens. You'll need to trim a tab out of the plug end of the bulb to get an h9 to fit an h11 pigtail and trim some depth off the neck to get it to focus a beam from the reflector.
So... You might wind up with two different lights, modification of the bulb and two different colors, yellow and blue white, of light throwing two different patterns.
Just stupid stuff I know from setting up off road and dive lights back when bulbs were exxxpppennnsivvve. And housings were worse.
