Video Transcript for Custer LED Safety Light Review

Today were going to be taking a look at the Custer red LED emergency light with heavy duty magnets. Its part number is HF18R-HD. This is also available in amber as part number HF18A-HD. This four inch by six inch emergency light offers to modes. We have a strobe mode and a solid mode. As you can see it's 16 LEDs that light it. It runs off of four AA batteries which are sold separately and it offers a run time of up to 32 hours. With the rear cover removed as you can see all the way around the outside of the battery housing here there's a nice gasket that's going to help keep the water and stuff from getting inside there and causing any kind of corrosion. As we said before, it uses a standard set of four AA batteries.

We're going to place them in according to the emblems that are on there. When we place our cover back on one side is going to have a rounded indention in it, the other side solid. That rounded indention should be facing towards our button. Let's give it a quick check just to make sure it's working. Yeah, as you can see we've got power, so we're okay to replace our cover. We'll press down firmly until it clicks.

Place our small slotted head screw back in and then simply tighten it down a few turns that it requires for it to be secured. Our safety light can be easily attached to any metal magnetic surface. Whether it's going to be transported in a tractor with heavy equipment, maybe a trailer. In our case today we're going to show you what it'd look like if you we're stuck on the road, stranded, your flashers are out whatever the case may be, maybe your battery is dead. We throw this on the back of the car, clip it in, hit the button and it's going to notify any other motorist about our situation to let them know that something's going on here. Now, another nice feature that we've discovered is that by removing the two magnets from the rear there's a little plastic tab that you can pull out. Slide down until you hear it click into place and it's actually going to offer a nice kickstand for the light. Maybe if you dont have anything that the magnets will connect to you can actually set that down on the ground behind your vehicle, maybe on the bumper, tailgate or something like that and still have the option of using your light. We've set our light up just over a tenth of a mile away from our cameras just to give you an idea of how right it is. The light can actually be seen about a mile and a quarter away.

That will complete today's review of our Custer red LED safety light with heavy duty magnets part number HF18R-HD. .

Red LED Safety Light with Heavy Duty Magnets - HF18R-HD

Average Customer Rating:  4.8 out of 5 stars   (42 Customer Reviews)

6" Long x 4" tall, red safety light with long-lasting LEDs warns motorists and pedestrians of your vehicle's presenence. Cordless, battery-operated unit with magnetic base can be easily mounted anywhere.


Purchased 2 in 2021 for extra illumination on a 4x8 utility trailer that has trailer connection lighting to tow vehicle. They are plenty good and bright. They require 4 AA batteries. Access to batter bay requires a flat head screw driver. The battery compartment seems fairly well weather protected (+) Note to boaters DO NOT SUBMERGE them(-). I use them only on long tows in rainy weather or at night to boost visability/safety. They only mount to steel. The magnets are strong(+), But, there are no screw, bolt, clip, strap, bungee, zip tie mounting provisions (-).


The service was very very fast, arrived I think in 5 days. But one of the lens was cracked. To much of a pain to box up and remail so just super glued it. Have no clue if happened in mail or? Lights good, they stick good, very bright, brighter then normal tail lights wired in. Handy to put on tractor or combine or horse trailer with magnets.. I am a farmer an rancher and pretty handy. I had holy hell getting back off to put in batteries, needs illustration as to where the actual hooks are that clasp them shut. It shuts very tight which is really good to keep water out, but if your opening for first time you do not know exactly where to pry. Directions no good as says just pry in middle but clasps are actually to left an right of middle. So you actually need to slide down more closer to clasps to break it open. Second time not a problem. But first time and haveing no clue how it clasps It was a bitch, but bright, arrived fast, and wanting honest feed back is really good for businesses as it actually sounds like ya all care... Thanks.. also make sure the links work with out having to copy and paste ... would be easier ..


E-Trailer delivered exactly what I needed and quickly.
So far , the light functions great, as designed.
I have purchased products from this firm previously with similar results.
Could not ask for more. Thanks E-Trailer team.


Product is exactly as described. Good LED brightness. Strong (removable) magnets. Excellent fit for my purpose (hazard and reserve marking lights).


Very bright with a two very strong magnets. Will go on the back of my vintage race car as a rain light.


Totally SatisfiedThis was my first order from this company. I received a prompt acknowledgement of my order and shortly thereafter I received a notice that my order had been shipped. When I received the order, the quality & performance of the Safety Lights exceeded my expectations. And their pricing is competitive. I placed a second order as a gift for a friend and he experienced the same results.


Be sure to make sure your vehicle works with a magnet!


Neat light. Great addition to MaxxTow carrier once you add the bar handle from Ace Hardware to the back name plate so the magnets on the light have a place to attach.

Portable and still bright is the key to the unit. Still working great.

Lights are better than I expected. I will use these as trailer running lights on my travel trailer, as it seems to blow fuses during heavy rains and the running lights short out. This will solve that problem as they are very bright and the magnets are also very strong. Thanks for solving my problem. Sorry no pics as trailer is in storage for the Winter!!


I bought these lights for when I haul oversized loads. They are super bright! Magnets seem pretty strong, just slap them on and go. Great price, I can't comment on the battery life, but it's worth it for every mile extra that I can run in states that require lights at night in places that it's impossible to wire light directly. Very happy with them! The only downfall is that to change the batteries requires a Phillips screwdriver for 2 little screws.


These lights are just what we need right now. Taillights on our vehicle went out and it is a very costly computer repair. This will keep us safe and legal in the meantime. Shipping was extremely fast, had product in hand 2 days from order on standard shipping! Highly recommend product and


This is a bright and multifunctional safety light! Powerful magnets allow portability and confident attachment to metal. Rough travel path conditions may require a structure to prevent the light being knocked off it's mooring. This is the second light I have, and this one has a single screw holding the battery cover instead of the two long screws through the magnet, facilitating battery changes. I primarily use it on my Cub Cadet Volunteer all terrain vehicle when operating on or near roadways. I have also taken it with me and used it on ensilage wagons which don't have lights or wagons for hay rides.


These are great. The taillights on my trailer go out and these are nice in an emergency. Magnets are very strong and will hold even on a bumpy dirt road. Took these things up and down the 25 mile stretch up in Polebridge, Montana and these stayed on without any issues.


these lights are way cool, if you have wiring or other lighting problems just slap these babies on and you are safe and able to get to a repair shop or get it fixed later. thanks for supplying these for us

still working great i leave em in the truck for whenever i need some extra taillights thanks for the great product

These lights are standing in admirably for my defunct tail-lights on the pickup truck. The magnets are hard core - won't budge even when I've bounced over some rough roads. And the lights are quite bright enough. I figure it was cheaper to get these lights than to pay to have the tail-lights fixed. The only drag, of course, is that I have to turn them on and off manually - but that's small inconvenience and worth it, since now I can drive my truck at night again!


Fair prices and quick delivery


These lamps seem like a good quality product. We will see how they stand the test of time.

The company shipped lightning fast and has a great follow-up communication system.

Highly recommended


Perfect for what I needed. It's a good size, and very bright. With the 2 magnets, this light isn't going anywhere!
Thank you :)

No problem. The lights are still going strong!
Lori O - 09/23/2016


i use these lights on diffrent trailers i pull around local.lights are very bright ,and always dependable. thanks etrailer


Product shipped fast, was delivered undamaged. Product met and/or exceeded performance expectations. Would like to see comparable products developed that are half the size in the future.


Total of 4 items purchased. 1 over a year ago and 3 just recently. All function great-steady on light or pulsing light at your option. I use 4 lithium AAs (L91s) as lithium performs better under colder conditions. Magnets work well on the back of my carrier.


Great product. I use day and night Magnetics really strong I just stick on back of my farm equipment.


Very Happy with product and service of etrailer.


Have ordered from them before. Quick service, great products. I highly recommend etrailer.


great products and also great delv. time

  • What is the Battery Life for the Custer Red LED Safety Light
    I checked with the manufacturer and the Custer Red LED Safety Light with Heavy Duty Magnets # HF18R-HD will flash up to 32 hours or more with 4 AA batteries. The quality of the batteries can affect performance.

  • Magnetic Battery Powered Lights to Be Mounted on a Trailer
    We do have some magnetic lights that operate on batteries. They're technically emergency lights but they have a constant shine setting. Of course they will not operate as brake or turn signals which I cannot recommend you tow your trailer without. A few examples: # HF18R-HD # HF18R-MB # HF18A-MB You might want to have your truck checked by a mechanic, if you haven't already. I know it will cost more money but if you're paying a shop to perform the repair it should solve the problem...

  • Recommendation for Red Trailer Light without Wiring
    I may have a solution for you, however we do not currently carry any standard trailer lights that will not require connecting some kind of wire or harness in order to receive power to activate the light. We do offer red trailer reflectors like the Optronics Rectangular Trailer Reflector - Red # RE15RK that will provide better visibility when compared to tape. These can be mounted with the adhesive backing or with two screws. I have attached a short demonstration video for you to check...

  • Recommended Heavy Duty Magnetic Red Warning Lights
    We have the heavy duty warning lights in amber as you stated, like # C43A or # C4500AW. For emergency red lights, I recommend the Red LED Safety Light with Heavy Duty Magnets # HF18R-HD or the Adjustable Red LED Emergency Light, Magnetic Base # HF18R-MB.

  • LED Light for Trailer Overhang Compliance Laws in Montana
    One of the best products we have for this situation is the Red LED Safety Light, part # HF18R-HD . This is a magnet-base mounting light that offers high visibility and is battery powered. Another option is the LED Safety Flare, part # PTW2368. This flare lasts for 50 hours off of batteries, and includes a magnet for mounting to metallic surfaces. If your canoe is not magnetic or doesn't have an appropriate mounting plate, you'd need to fabricate a way to secure it to your trailer load...
