Universal 12-24V Emergency Strobe Warning Lights 6 LED 12W Surface Mount Beacon Hazard Warning Lights Flashing Light Bar for Off Road Vehicle, ATVs, Truck- 4PCS (Blue)

Bought these to add to my motorcycle brake light. I wanted something that would strobe enough to get driver's attention, something a little more than my current LED brake light with modulator. I figured I'd try these at $20 for four lights. I modified a bracket and installed 2 lights on the bracket. (As seen in the picture.)First, the light patterns are plentiful and there's enough that meet your liking. Unfortunately, and I don't know if this is due to not enough power coming into the brake wire or that the lights are faulty, but when I set both lights to the same pattern and wrap up the wiring, upon restarting the motorcycle there is always the one light that goes BACK to the default pattern while the other remains. I tried another light install to see if it was just that one light that was faulty...nope! The third light also.I have both lights running off the same wire. I have no problems with the first light keeping it's pattern selected but the second 2 lights installed both went back to default (pattern #1).As for the brightness...I think if the background was blacked out they might be a little brighter. But because of the shiny silver background these lights seem somewhat dim. Not enough to where it's almost "unseeable" but in daytime - forget about it! Just not bright enough.These lights are probably better used on a car somewhere but for a rear motorcycle brake light add-on, I'd suggest going with something more expensive like the Wicked Strobes.

Plastic base instead of metal. I'm okay with that as long as they last. However... when testing these lights; they got extremely HOT!!I have the same 4 LED lights in various color combinations from other sellers. They burn cool to slightly warm as one would expect. I can't imagine why these would be different; but I do NOT feel comfortable mounting these on my vehicle or anyone elses.I'll be returning these blue LED,'s.

The media could not be loaded.  I placed these on my son's power wheels car tapping off of the 12v feed from the battery. They pull about .75amps at 12v DC. Incredibly bright, could see these on a golf cart or other small vehicle. Not as bright as a classic wheelen brand light but for small projects it's great. I was impressed too with the assortment of pre loaded flashing sequences available. Touching the yellow wire to the positive terminal with the black and red wires already connected to the battery allowed me to cycle through the various modes.

The media could not be loaded.  Worked as described. Will be updating in about a year as these will be on the back of trailer used to haul a UTV. I made a harness for them with a button. Some of them wouldnt stay in sync while i was making the harness but after spamming on/off switch and pattern button simultaneously they all reverted to steady on snapping them all into sync. 🤷🏽‍♂️Don’t really care if they stay in sync as they are just emergency strobes to be seen

Receive package and while installing one unit of the four would not light up. contacted seller and they said a replacement would be sent but it would take a little longer. It has been close to two months and the single unit has not arrived. I did not realize it was going to take that long for me to complete my project. The other three unit or lights work great.

I have 2 front and 2 rear on my car, and both the right side lights are now in a different pattern than the left. they have been on for almost a month, can I return? They are worthless like this and I would have to un-wire everything to get back to the same pattern, and who knows how long that would last. Can I return?Would be 4 stars if they stayed synched.Update, now they have gone out of sync again, and 3 LEDs are dead in less than 5 months. Will be replacing with a different brand.

Not Police bright, but ok for trail riding in daytime and getting noticed at night.Only pattern all 4 returned to was L3double then R3double flash....yellow wire switching patterns unreliable-even tried separate wire back to battery ground=still not switching as advertised. SAD mounted one-not pattern wanted. Ok for Emerg alert.Good, base was solid aluminum:)

Had a customer that didn't want to pay for the higher end name brands so I got these for him. He's happy but they're not the bright especially during the daytime.
