LED Red Blue Emergency Strobe Lights for Police Cars Law Enforcement POV Patrol Vehicles Trucks, Waterproof 2 in 1 Surface Mount Grille Safety Flashing Lightbar

Nice and bright

The first item did not change modes by pressing the switch, I took it apart but I’m guessing it’s a flaw on the board, all things were wired well. I clicked on the seller name in the item listing & let them know I couldn’t fix it. Ken assisted very promptly, apologized & made it right, it was a good experience & he was great to work with.The brightness is good, color is good, lens is good & casing is good but no waterproofing (glue, rubber or otherwise). The one with the switch going in has circuits inside, the other one is just an LED so keep that in mind when placing due to not being very waterproof.I tested with VOM in ‘all on’ steady mode since that’s all that worked for me, they pull about 800ma. The chips & led strip both got to 140F after 10 min at 75F ambient. The led got to 170F with no heatsink & still worked. The led strip has a washer glued to the back on the white side to transfer heat as it burns hotter than the amber by 20 degrees or so. It seems to do the job well enough as the casing gets warm to touch. I let the bad one run all night @12.5v DC & it still worked the next day.I looked up the chip in the middle, it says it’s an 800ma voltage regulator that can accept up to max 15vDC input. So make sure your power is under 15v. My truck spikes up to 16 so I’ll need a regular but I am use to it & have several.

Extremely bright. I used these lights to replace a $400 set of stealth visor lights as they do not mount correctly in my new vehicle. These lights are not only brighter, but are extremely low profile and lightweight. I was actually able to mount these without drilling anything because of how light they are. Install and wire tuck took less than 10 minutes. There was more than enough slack on provided wires to run and tuck entire thing on a full size truck. The only place I had to add wire was from the switch as I chose to wire directly to the battery. The switch box is a bit cheap and definitely feels fragile. It would have been nice if they provided double sided tape or velcro for the switch box. But if you have experience installing aftermarket LED light systems, you'll probably have this stuff laying around like I did. I definitely highly recommend these lights. I have installed LED light bars, surface lights, visor lights, traffic advisors and many interior and exterior light systems on many vehicles including small coupes to full size trucks and SUVs. These were by far the easiest install of any product I have used. Pick up a few pairs and be seen when you need to be. Smarts reside within the LED module itself so splicing multiple pairs into the same switch is not an issue. 10/10 on this product.

Just installed these on my Kubota tractor for extra safety lighting. These are BRIGHT and really get attention. Easy installation, low power draw, various flash patters and built very rugged. Highly recommend.UPDATE: After 3 uses on the tractor, the flash patterns quit working. They do turn on, but stay in a constant on mode. I really liked these as they really grabbed attention and were very bright. Kind of disappointed. Will attempt to contact seller and see if there is something they can do to help me out.UPDATE #2: After contacting the Seller, and explaining the issue, they sent me a brand new set immediately. This, even after the 30 day return policy expired. Excellent customer service. I will certainly be purchasing from this seller again.

First and foremost, I am reviewing these based on how they operate and function for a set of lights that cost $30.I am not comparing them to something from Whelen or any other major light manufacturer. I also did not install them as they came out of the box, they were custom fit to work for my application.The lights were benchtested to see if they worked out of the box and worked perfect. both the on/off and momentary switch worked fine.This unit gives plenty of patterns to choose from, however there is only one pattern that I truly use.They are bright, and a excellent choice for side lights. Be advised that these are Linear LED lights. If unfamiliar, look up Tir Vs. Linear.I have them mounted inside my vehicle, so I can not comment if it's water resistant/proof.All in all, these are a great option if lights are needed and your budget is limited.
