12" 36W White LED Emergency Flashing Mini Light Bar - Waterproof Magnetic Roof Top Mount Strobe Warning Lights for Trucks Golf Cart Tractors Vehicles Cars Forklift

Pros:much brighter than the competition at this price! I believe the others only offer 18watts in this price range. 18 Watts may be fine for night but too dim for daylight hours IMO.Comes with (2) magnet/ suction cup mounts which held great in my Security vehicle up to speeds of 45-50 mph with no issues.Extra long cord with nice rubber flexible feeling.Cool switch on the 12 adaptor end that has two functions. One is a lighted on/off function and the other is a momentary rocker switch to advance through the other modes. (16) in reality as they consider “off” a mode. Also maintains last rememberance mode which is nice when turned off!Cons:not large (they offer a larger version for $100) so may be smaller than many would like but standard in size at this price range.Only have used for a week so longetivity cannot be commented on. I have had other similar type of lights and this light seems to be well built in my opinion.Some reviewers mention it doesn’t hold up in a 4x4 environment? Duh! What does hold up in a 4x4 off-road environment for $40? If it gave you 4-6 months in a punishing environment, this price is a steal for the sheer brightness of the light!Used for a week on hot summer days. Should be water resistant obviously but I cannot comment on that.Summary: best light I have purchased in a few years for the amount of brightness it puts out, the quality materials used and overall great price!

I was very satisfied with how bright the light is. 36 watts doesn’t seem like a lot but it does an amazing job. As a first responder I stop for accidents and folks on the side of the road who are broken down and I needed a light that would show ip in all conditions so I wouldn’t get hit. This light delivers all that and more. The dual light with the alley light puts out excellent 360 degree coverage so you can be seen anywhere which means safety. It is a compact light thats not obtrusive but it puts out the same light and a full size light bar given its size. I have purchased two and looking to get a third for another service truck.

This unit replaced my 'road warrior' Grote Roto-Beacon (35 years old & still dependable, but awkward to store in limited space). I needed a more compact unit, that easily stores when not in use, for temporary mounting on my personnel vehicles when I needed them on jobsites. This unit has a great variety of dynamic flash patterns; and, two subtle 'rotating' patterns for times when you want to be visible without the blinding glare from a rapid flash. Stows easily in my gear box, and ready to go when I need it. I have not tested the magnets at highway speeds; I only need to use it in lower speed areas.

Indiana Vol Firefighter. Ordered one for each of my vehicles. Pickup truck with sunroof - mounted behind sunroof. Suburban - mounted about 18" behind windshield. Both have stayed on at high highway speeds while on run. Very bright at night and are perfect brightness for nighttime and being able to have other traffic see around your lights. The all blue is noticeable during the day - but not attention grabbing, hence the one star loss there. Easy to use and have some great flash patterns. I would recommend setting back from windshield when attaching. The sub died and moved to a car with a panoramic sunroof and had to put them closer to front windshield that I would have liked, and well... first semi I passed doing 55 and the light grew wings. Nice thing is the cord let go so no damage to car and no one behind me so no damage there, but the light did meet it's end in a spectacular spray of plastic and LED's. Definitely want to keep out of the airflow if mounting. Otherwise, it rode on truck and Suburban for >6 months with no issues, only the aerodynamic car cause the loss.

This little sucker is BRIGHT! I am using it right now while working a road job. While sitting under this overpass it is bright enough it illuminates the entire area. I have used it during the day and it was still very bright and got the traffic's attention. I have received several compliments on it from other officers. The only draw back is the light is small and in my Dodge 2500 with the way the roof slants you can only see it from either the front or the rear but not so much so from both unless you are far enough away. I will by a larger light bar next time for the truck, but this should work well for car that sits lower.

Quality safety light if you don't want to look like a city works truck, all as advertised but it may get some moisture accumulation if left on the vehicle under damp conditions.

I got this to use for work as a rural mail carrier. So far, so good. I got the all amber version and wish I'd gotten amber and white. I think amber and white would have been much brighter. However, the amber is bright enough, it is visible in the daylight and I feel much better about whether other motorists can see me or not (as part of my route takes me down a hilly, curvy highway heavily traveled by log trucks 😬)I am mainly writing this review to share with others that I commute 20 min on an interstate to work, and back, traveling 75-80mph and this light has stayed put.

I've had this light for about a month now, I almost didn't buy it because of other reviews saying it would blow off the top of the cab. I have had this on during a blizzard, going into a 35mph headwind at 60mph, traveling down an interstate at 70mph, in rain and snow. I have had no issues with this light moving or coming off. I made sure to clean the spot I placed it very well before placing in the cab. There as been no issue with the seal, no moisture is getting into it. It's bright, reliable, and I will get more the rest of my fleet trucks.
