SpeedTech LightsK-Force 27 Mini Light Bar 168 Watts LED Strobe Lights for Trucks, Cars, Plows, and Emergency Vehicles with Magnetic Roof Mount - Amber/Clear (Yellow/White) Alternating

These strobes are great. They are super bright and last for years. Customer service is their top priority. One thing to note is that you will need an extension cable to install these on most vehicles. To do that you have to contact speed tech.

Every thing was as expected

I haven't installed this light yet but, it seems very well built, shipped fast and very nicely packaged.I looked at a lot of lights over the past couple months. This one was a little more expensive, but I really like the quality.

Been purchasing this brand for years for work trucks. Lights are insanely bright and get several years out of them with no problem.

very bright and works awsome

I must say this seller is very prompt with shipping. Upon opening my package it was very professionally packaged inside. Installation was fast and easy. I ran some tests during the daylight to make sure all functions worked and I'm pleasantly surprised. There is only one thing I would change on this product and it's how the wires come together to meet the control box plug. I will be securing them better with electrical tape. Heat shrink or flex tube would be great in this area just to protect the wiring better. I will include pictures and possibly a video at a later time.

Excellent product! I used it to [magnetically] mount on top of vehicle used to escort cyclists on roads.

Now THIS is what a light bar is supposed to be! VERY bright, even in the brightest part of the day, and a lot of flash patterns [30] to choose from with a very nice yet small grand control box. I also have the Striker TIR 4 light bar, and I was able to hook it into the AUX port on this bars control box so I can control both from the same control box. Very handy. You can hook any light to the AUX control. It doesn't have to be another light from STL. There is a power cap on what you can hook to the AUX. It will be listed in the manual.The control box also lists independent Take Down control, but it's really alley lights. If you have that turned on, it will override any flash pattern if you have the whole light bar on at the time and the alley lights will stay on steady.My preferred flash pattern is the last one: random. Helps keep people attention when it's changing patterns every few seconds.Installation is a breeze. Just decide where you want it on your roof, and the magnets will hold it in place no matter how fast you drive or what weather you may be experiencing.The wiring isn't quuuuuiiiite long enough for a 4 door pickup, but if you have 6-wire thermostat wire laying around it will be easy to splice and lengthen. The only downside to a light bar with more options, is more wires lol. I can only imagine how many wires are in the 36" and up light bars that have cruise lights, take down lights, and traffic advisor buttons on top of what the grand control box that this light bar has.The grand control box comes with a mounting bracket. The buttons on it have a blue backlight when they're selected. Honestly though, during the day, the backlighting is not anywhere NEAR bright enough. I've had to cup a hand around to double check that it's on/off waaay more than not. That's my only complaint minus the wiring being a few feet too short.This light bar won't disappoint. If you're wanting one that has traffic advisor feature, that starts with their 36" bars and up. If you're wanting a good sized bar that won't completely break the bank, then look no farther than the K-Force 27" 'mini' light bar.**UPDATE**Once it started getting below 50° outside, the first 4-5 flash patterns don't work. They'll be frozen in the first part of the pattern. Emailed STL and they replied that's never happened before. I've never seen any lights do this in cold weather, and I've had cheap and pricey lights, all of which worked fine regardless of temperature....until this lightbar. If I can ever get around to calling STL during business hours we'll see if they stand behind their products and ship me a replacement that doesn't only work in warmer temperatures. Minus this, I love this lightbar! Had to lower rating from 5 to 3. If they do me right when I call, it'll go back up to 5 stars.
