Great complement to your 1st class security system. Warn potential thieves of the beast they're dealing with. The built-in blue LED that came with my 5901 was too shy, so I added the 620V in the corner of the windshield. Pros: - Mostly everything. Nice design, scary enough, easy to install. Cons: - Not clear where and how to stick this thing to your car class, and no instructions provided either. Some tips: The film on the back is for protection only - just peel it off. The adhesive button is on the front. Do some tests before you stick it to your windshield, since you won't be able to move it afterward. The light is strong enough at night. I don't recommend placing this indicator at the top of the windshield, unless you want your car to be seen from the moon.
