XTAUTO Super Bright Red Blue LED Warning Strobe Light - Waterproof 12-LED Caution Emergency Construction Beacon Flash Strobe Light Bar for Car Truck SUV Pickup (4-Pack) Review

I bought these to put on my car. These are three wire lights; However, this is not a problem; They are very dark and not bright enough to use in daylight. I bought similar lights two years ago, they were 5 wire and they are very bright and you can sync flash circuitry to multiple lights.

I have not installed them. The switching mechanism is different as you need to connect the extra wire to positive instead of ground to get a pattern change. Pretty bright. I'm concerned that the seal on the back of the device won't stand up to the weather as it's poor quality at best. The time will show. I will rate higher once I get a chance to install it.

Every time I turn on the light, one of the four lights changes mode. It's wired correctly - red wire to on/off switch to positive 12v supply, yellow wire to separate switch also on 12v supply for shift changes, black wire to ground. 3 indicators work the same on power cycle, but 1 indicator changes. Disappointing as I bought this in October 2018 and just installed it and now I can't return it. GRRRRRRRRR!

Firstly the lights I ordered have 6 orange LEDs on one side and 6 white LEDs on the other side. This is not the case with the ones I received, they have 6 orange LEDs on the top row and 6 on the bottom. To add to this insult, the yellow wire for pattern select doesn't work. You cannot change the template at all. I had an old set on my old work truck and really liked it. It's a shame I waited so long to install it that I can't return it.

These lights are very bright. You need to connect yellow to positive to change the pattern. There are many patterns I like both in lights but they won't keep the last pattern, in other words you set the pattern you like and turn it off and when you turn it back on they should dem follow patterns you set, however they do NOT follow a random pattern of at least 12. I have 3 of them. . Revain does a great job of sending out new ones, but still.

I installed them on my trailer for safe lighting and warning. At first I was happy and satisfied with the purchase, but after a month the waterproof seal failed and the headlights were filled with moisture from constant rain on the streets. But the light worked so I didn't mind. Shortly thereafter, I worried that the light was wrong. They dimmed where they were barely visible, and a few days later the other light didn't flicker. Shortly after, I emailed asking for a refund or exchange and…
