🚨 Syneticusa 3157 Red Flashing Strobe Blinking Rear Alert Safety Brake Tail Stop High Power LED Light Bulbs: Enhanced Safety Lighting for Vehicles Review

Let's see how long they last. but at the same time they were easy to install on a 2006 Yukon XL Denali and my teenager was able to figure it out for himself. The lights are quite bright and are sure to draw the attention of those following behind.

The headlights look great, but the turn signals flash very quickly. Annoying that it needs resistors as my other LEDs don't need resistors. The headlights were removed and just regular 3157 leds fitted and needing g resistors was no problem.

They are supposed to work on my 2004 Ford f150 fx4. THAT DOES NOT WORK. When you turn it on for the first time, it flashes dimly and that's it. There are NO brake or turn signals when using these lights. They are designed for a single element bulb, not the dual bulb my car requires.

Brake light works as advertised, the problem is that it made my turn signals very jumpy so they flashed twice as fast as normal. They even flashed my reverse light backwards so I had to take them off and put the old ones back on. Now everything is back to normal. :-((

A little dangling in assembly but I just bent the wires a bit and applied some electrical tape. I had another set that flashed about 5 times and turned on before staying on. One day my wife followed me and said it was a bit confusing as she thought I would turn around or stop so I tried these instead. The lightning on them is a lot less confusing but still works great! I wish they were a little brighter but for the price I can't complain!
