High-Performance SpeedTech Lights Z-3 LED Strobe Light - Ideal for Police Cars, Construction Trucks, Service Vehicles, Plows, and Emergency Vehicles. Surface Mount Grille Flashing Hazard Beacon Light with Clear/Clear (White/White) Color Review

I have a Z-3 on the door sills, mirrors and grille. I started with 8 pieces but after installing them I had to buy more. I bought 2 for the grille and installed them today and here is the video. The only problem I have is that I can't figure out how to sync them alternately. It says you can but only mentions Multicolor.

The lights are not bad for the price but you get what you pay for can flash them independently but you only have a sample, i tried using the flash module to see if they would like, i wanted them out of luck, save yourself the headache and buy fenex brand lightbulbs how you can do it bunch of different things.

I've been following this company for a while and when they got SAE certification for their lights I decided to give them a try. I bought 2 lamps and in a month moisture appeared in both of them and one soon died. They quickly replaced it, but the second one broke after a few months. Save money and get a better brand like Fenix, Whelen, etc.

Excellent quality product at a great price. It's not nameless junk you can get for a few bucks less. Service and support at the highest level. These modules are bright and vibrant. Functionality limits the nested pattern to a single flash, but there are many great concurrent patterns. I recommend using 4 or 6 LED modules for interleaving applications.

If you want all the lights to flash at the same time, then that's fine. If you want them to alternate, you have a pattern.on.off.on.off. I still love the headlights and am returning them for the Z-4 which are two tone and don't have the above issue.

They're nice and thin and seem very beneficial at first glance, but they take about half a second or more to fully ignite when powered , and they always work very well. a succession of faint flashes before they light up. Regardless of what pattern or steady light is programmed, they will always flash briefly and not be at full brightness when the unit is turned on. Because of this delay, they cannot sync with other lights that use turn signals or stock turn signals, hazard lights, reverse…

Before I start this review I have to say that I myself am impressed with the packaging and the care that is taken to ensure the merchandise gets to me undamaged. These lights are exceptional to build and have a very solid build and real glass finish which I didn't expect for the price. Not only are these lights bright, they dazzle at night and are incredibly visible during the day. I have a TIR with a field of view of about 35 degrees so you have to be careful where and how you install it to…
