Review on 🚨 18 Inch Ultra Bright Lightz with Large Gasket - Optimal Emergency Warning Visor, Dash Stick, Surface Mount Light for Windshield Flashback Guard by Jeffrey Shatzel

One works well. For some reason the second sags on one side. First, I'm sure it would be easier to mount them on a lightbar with a metal case, mines on an STL plastic case, so it's a bit more difficult. I had to remove the lightbar from the mount, not a difficult task so it's fine. They are 19 to 19 1/2 inches long so I was able to easily cut them with the Raptor shears. I used a flathead screwdriver to put dish soap in the groove and bend it about every 3 or 4 inches. Once I got it on, I flexed the rubber and pushed it with my hand until it was fully in the groove. Squeezing a little more until everything was nice and tight, I reassembled the light bar to the bracket. My light bar is a permanent mount so you can't pull it out all the way, it was still pretty easy. Has held up to the Texan heat with no issues so far and reduced the breakout A LOT. 4 stars because one is sagging and they're only a week old. Even with a slack, I won't bother returning, a little gorilla streak and you'll be fine. Doesn't prevent side light, but I fixed it with a small piece of black plastic and tape. Looks good, works. There is only one in the package.
