SpeedTech Lights Mini 21 120 Watts LED Strobe Lights for Trucks, Cars, Plows, and Emergency Vehicles with Magnetic Roof Mount (Blue/Amber Alternating)

Installed on a 1500 ram extremely bright very happy with quality works well I love the multi settings and the auxiliary for my front light bar as well

Easy to install and the led strobe lights are very very bright, I am very happy with my purchase.

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.

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.

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

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 light bar. Bought this a little over a year ago. Rolled my truck three times doing 65mph and looks and works likes it’s new. The light bar never moved on my truck. Super strong magnets. The lights are very bright and easy to see. Customer service is great. Well worth the money.
