The middle ones are the 9" and the ones on either side are the 7"
This is another photo with all 7" I was originally going to put two 9" ones on the brush guard and two 9" on the roof rack but then i figured that would be overkill so i stuck with all 7 and they are plenty bright.
Here's a shot of them next to each other for size comparison. The 9" ones aren't really that much brighter it's really just a look.
These are the exact ones that I have for sale. I have both 7" and 9" brand new with a one year warranty. I'm actually an HID dealer, I sell and install conversion kits and off road lights. It's kind of like a hobby/side job.
