good deal and good quality, simple and easy to use
This size makes it easy and convenient to have more than 1 mounted on the vehicle without being obvious, which I like a lot. The lights work as described and are durable
I ordered mine with the added L-Bracket because it's just so cheap, and it made mounting even easier than without, so I recommend that. The red color is fine and it's a good light
Great look and feel, very happy with mine
The wiring makes installation pretty straightforward but also reliable and stable
great product, everyday wear doesn't affect the brightness or flashing at all
