Xprite 4PCS LED Emergency Strobe Lights, Red Blue 12-LED Surface Mount Flashing Strobe Lights, Sync Feature Ultra Slim Grill Light for Volunteer Trucks ATV SUV Vehicles

So far I am extremely pleased. I have not experienced an issue yet, and they are extremely bright and a good buy for the money. They sync and work just like you would want. The only critical thing I can say is it does not have a alternate sync, but for the money savings over name brand lights I am fine with that. The wires are sealed in the back so water intrusion from the back should not be a problem. I did read where some said seal the lens with silicone before installation because water gets in. I have not experienced this but bought extra just in case. I will try the silicone on the next set if that becomes a problem.

I installed 2 of the 4 light units that I bought on the front grille of my 2019 Ford F-250. I haven't yet decided where to put the other two units. I spend a lot of time on the highway towing trailers up to 35 feet long. If I must stop on the roadside, then reliability (i.e. superior weather-sealing) and brightness are imperative for my safety. Unlike some LED lights that I have tried and discarded, these appear to be very well sealed where the wires come out of the back of the unit. To date, I have gone through heavy, driven rains at highway speeds and the lights still work great. In terms of brightness, I want lights that are so bright that no half-asleep motorist can claim that they didn't see me. These lights are at least as bright as those that I have seen and used. I've had them on my truck only a couple weeks now, but so far I'm 100% satisfied with these lights. Safety tip: Don't synchronize your lights; set them up so that the units flash in different intervals and patterns. I believe that doing so better catches and holds other motorists' attention.

Brightness quality of whelen. We'll see how long they last though. The clear cover for the leds is pretty solid, the backing is half as sturdy, if it's not perfectly flush when tightened down it cracks. Otherwise Sealed and water proofed. Each light came with plenty of wire to connect to, at 16gauge. Sync instructions are grammatically confusing. Starting at the first light, run the gray wire to the white wire on the next light, then from that light, the gray wire goes to the white on the next, and so on. 9 different strobe patterns is nice, will need to wire in two switches, one for on and off, another to connect yellow and ground to change patterns. One of the lights came with only one sync wire, i assume this was either the beginning or end of the circuit if all of them are wired together. All of the patterns have at least one set of lights flashing, there is no steady on option.

Can't beat this value. Bright leds for a great price. Cant rate longevity yet, but out the box they are just as nice as brand name strobes 4x the price! Purchased another brand from Amazon that was similar price per strobe but brightness and quality didnt compare. I returned them and ordered another set of these!

The media could not be loaded. Great for the price wish they came with scews or bolts to mount them with. Second set i ordered came with the screws needed the lights are perfect just not completely waterproof. Will definitely buy again

After about three months, I had two lights get water in them and stop functioning properly. After a year, I have an additional three lights stop functioning due to getting water in them. While they are bright and do what I needed them to do, replacing them all the time is not okay.

The media could not be loaded. I love it and easy to install. It come with everything you need. The instructions are super helpful.

These lights are pretty basic with limited functionality. They are not very bright either. These lights do not have multiple modes, they do not sync together and the flash patterns really aren’t that great. These lights would be okay for a dump truck driver needing lights for a construction site or something like that. I don’t recommend, to any type of emergency responder, buying these lights. They aren’t very bright during daylight hours.

Lights burn out after 2 months.

Out of all 10 only 1 light is broken I will only flash on one side

The media could not be loaded. Right off the bat I’ll say that I have had many Xprite products and none of them have disappointed me yet. These little guys are no different, I would say that these are easily the best bang for your buck surface mounts on the market. Now obviously you can’t compare these to something like Feniex or Whelen but for the average joe just looking to be more visible on the side of the road, these are perfect. I’ve had these installed for about a week now and haven’t had a single issue. They haven’t been in direct rain yet but so far there hasn’t been any condensation inside the lens like some reviews mention. Now the pro/con breakdown.Pro: -Very easy to install and wire even with very limited wiring knowledge.- flash patterns that will get your attention at a distance- the ability to sync multiple lights together for a more professional look- bright even in daylight- price point based on what you getCons: - limited flash pattern options- very hard to find any info about power usage or amp drawSo to finish off I’ll say I give these a 4.5 out of 5 simply because I wish the pattern selection was a little better. That being said, these lights are well worth the $30 price tag in my opinion. They seem to be well built, nice and bright, and easy to install. Can’t ask for much more!

The media could not be loaded. Very quick delivery, received product within 3 days of ordering to the Lower Mainland area of British Columbia. Very simple to wire and install. Synching is extremely easy. I installed and wired these on my 2013 Ram in an hour.Brightness in the day is actually better than I expected, I attached a video taken in the daytime to demonstrate just how bright they are. During the night these are phenomenal.Only thing I noticed was during installation I had put these on my truck grille that has a slight curve to it. When tightening the screws to secure the unit then I noticed the cover would ever so slightly separate from the aluminum backing of the unit. This is most likely where anyone complaining of these units not being sealed are wrong. Issue comes in due to installation error not unit error. I put some silicone along the unit where the cover and backing meet and so far it’s been great.I will try to update if any issues occur but so far I am very satisfied with the product and especially at the price point they are offered.

Time will tell how long these will function. The pictures are from going to a car wash and show condensation inside the lenses. 4 of the 6 installed on the truck are like this. When the temperature gets below freezing, these will not last.
