4-LED Sync Feature Ultra Slim Surface Mount Flashing Strobe Lights for Truck Car Vehicle LED Mini Grille Light Head Emergency Beacon Hazard Warning Lights (Amber)

Easy to install. They are polarity specific as I think all LEDs are. They have a programming feature, the flash pattern can be changed to seven different settings. The yellow wire of the four is simply tapped against a ground change the setting and then the light retains that setting. The lights can be linked together, so they flash in synchronization.

I recently purchased this product, and I must say it works great—better than I had expected! The performance has exceeded my initial expectations in every way. For such a great price, I am genuinely surprised at the excellent craftsmanship of the product. From the moment I unboxed it, the quality was evident. The materials used feel durable and well-made, which is often hard to find in products at this price point. Each component fits together seamlessly, showcasing attention to detail that is typically reserved for higher-end items.

Update: The company has reached out to make this right! Excellent customer service! Great people to deal with! Ordered this 4 pack. 3 light heads worked as it should, 1 light head didn’t - only half of the light head worked. What a shame, these lights are relatively bright.

An excellent product. Metal base, bright and easy to install.

This strobe light was great until it wasn't. It became inoperable and apparently burned up the diodes. The LEDs that were flashing are now black. Cheap components!

Are these top of the line strobes, No. you’re looking at $12 strobes on Amazon, enough said. Will you help you be visible in an emergency, yes. I bought these because I am cheap, but I made them work for my situation. Mounted 4 under my tailgate with 3M tape and synced them together. Very eye catching if you are following behind but they do not have any spread to the light. Had these for a few years now and have not had one issue. Would purchase more if you could sync more than 3 together correctly.

Buen producto, luz muy potente

I mounted this inconspicuously between my bed and tailgate on my truck for those times when I'm on the shoulder of the road. It's my personal truck and not often used for work purposes so the small size makes it hard to notice when turn off but it certainly gets your attention when it's turned on. There's several flash patterns selected by a momentarily grounding the yellow wire of the four that come from the back of the light. The white wire I believe is to connect two or more similar lights together so they'll switch modes together. I'm going to consider more of the these lights for use on our fleet trucks where I work if this one continues to impress me.

Impossible de connecter facilement à mon 4 roues. Quik connect impossible car pas les mêmes fils couleurs

I installed 6 and every one filled with water in the rain and snow then froze. None of them work. If one got water that would be one thing but all of them! I want my refund
