SpeedTech LightsMini 21 120 Watts LED Strobe Lights For Trucks, Cars, Plows, and Emergency Vehicles with Magnetic Roof Mount in Amber/Amber (Yellow/Yellow)

This light is VERY bright and definitely attracts attention. The magnets hold very well so I’m confident in its ability to remain attached at highway speeds with no problem. The low profile design looks great without sacrificing performance. The only negative I have is that it would be nice if the wiring for the control box was longer. I hard wired the light in my truck and the wire came up a little short but if your utilizing the lighter plug it should be an adequate length. Overall I would definitely recommend this product.

This is the second speed tech light that I own. First one is a 27inch and this is a 21inch. They are both great products will definitely be placing another order for 2 48inch. Easy install, long lasting, and great customer service experience.

The media could not be loaded.  My lights arrived very well packaged and safe. Surprised at how heavy and well made they are. Magnets are super strong and the wiring was sturdy. Super bright and easy to access all the different patterns for the strobes with the included controller. Can’t find anything wrong with these.

STL are not cheap... but you get what you pay for. There extremely bright, very reliable. Good selection of patterns. Never had a problem with them. I had other cheaper led lights that just don't last. Spend the money and know your getting a good product.

Great lights bright enough to see on sunny days. Installation is easy and control pad is convenient for operation. Magnets hold strong and plent of cable to set up however you need.

Great light put it on my 18wheeler only problem needs to have a higher mount bracket the low mount makes it hard to see on top of truck. Easy fix with 2” spacers. I have 5 more trucks to put lights on and I will be buying 4 more of these lights. Only bought 1 to try out first. I am impressed for the money

I have this light bar on my super duty for landscaping and plowing. Works as expected. Very bright very durable. The magnets hold perfectly going down the highway 80+. The only downfall I found was running this with a crew cab, the harness is a little short. I wish it was 2 ft longer but that’s my personal preference.

The lights the magnets everything works great super bright how ever big down fall is after having the light for couple weeks having some big problems with the control box and the light bar not working until I mess witch the control box other then that it's a great light
