Video Transcript for Blazer Light Buster Backup and Utility Light Review

Today we're going to be taking a look at the Blazer Light Buster. This dual function light serves as both a backup light and a utility light. It's designed to fit into a standard 7 pole connector, whether it's on your RV or on your pickup truck. Part number on it is C8020. As you can see, the light has two functions. With the switch flipped into the white dot direction that sets to utility.

Means our light's going to come on any time we have it plugged in and our headlights are on. In the backup mode it'll come on any time the reverse lights come on, to give us extra light when we're trying to hook up to our trailer, or just for safety's sake we're getting a better view behind us. The utility light's great for basically everybody. Whether you're a contractor, you're trying to get the last couple things done in the day and you need some extra light, or you're at the campsite, need to get your tent set up, or even at the end of the day, and you're trying to get the kids packed up after the park. This is going to give you that little bit of extra light that you really need to get it done. Now, the bulb in it is a standard MH16 bulb, very readily available and easy to replace. Also, the design of it, it's about the size of a standard flashlight, so it's easy to store it in the glove compartment or one of the storage compartments in the back of the vehicle. Installation couldn't be any simpler than this.

You basically just open up your 7 pole cover, slide it in, and then you allow that cover to come down and secure it into place. With it installed, let's go outside. It's still dark out, so we'll let you see what it looks like in action. Placing your vehicle in reverse is going to activate the backup light, allowing us to safely back up to our trailer. As you can see, once we put it in back in park the light goes off.

It's as easy as just flipping the switch here; it's going to illuminate our work space here, that way we can see what we're doing and get the job done. That'll complete today's look at the Blazer Light Buster Backup and Utility Light for 7 pole RV style connectors, part number C8020. .

The barrel of the light that fits into the socket is made of thin plastic and fractured the first time I removed it from my truck. eTrailer offered to have the manufacturer replace it if I paid for shipping it back, but, having had a chance to see the inside of this device, I am confident it won't last unless it is treated with kid gloves, which means it isn't a very useful tool for the rough environment around the back end of a working truck. 114163


Update: eTrailer refunded the purchase price to me, even though it was outside of their normal return window. I appreciate them reconsidering and making this gesture. The amount of money isnt large, but taking care of disappointed customers is huge.

I love this little gadget. After adding a rear view camera to my 2007 Tundra, this trailer plug mounted light made backing into my parking spot next to the house so much easier. I also love the little toggle on the underside that lets you turn on the light manually (so long as the parking lights are on) while I'm connecting my trailer for my two UTV's. My buddy had one for years and swears by them. I do to. You can replace the bulb with high intensity LED bulb aftermarket too. 329937

Where do I start. The light is bright. I have a 2012 f150 and it wont lock into the factory plug cover like all the rv plugs, so if I leave it in and drive away it will fall out. Not waterproof/resistant at all. The back plate for the terminals is held in place by a tiny set screw and it will come off, mine did and I ABS glued it back on. To sum it up made in Taiwan. No complaints at all about etrailer's service 5 stars. 105477

This light really improved the view in my mirrors at night. It's not like a powerful headlight by any means but it does improve the view in my outside rear view mirrors. The LED lamps that other people sell to install in your taillight assembly did not do anything of value. The instructions said that the replacement bulb should be 35 watts, not 50 watts as advertised; not sure what I received. 65208

The product itself is good. I have one on a prior truck. The problem is the new Toyota Tundra (like Toyota is prone to do) has a different connector. The light does not slide in far enough to catch the lock tab. It also sits 90 degrees to where it should so the drain hole is horizontal to the ground rather than perpendicular. 111138

Really lights up with vehicle in reverse. My 2016 Ram 1500 has so little light while in reverse I needed to use one foot on the brake in order to see. I've had it approx. a month and so far so good. Would give it five stars but the "utility" feature does not work. 345990

Simple product is affordable and works very well as intended. It fits snugly and the plug cover locks the light in place. It added the perfect amount of additional light for my aftermarket backup camera to work in all weather and lighting conditions. I'm happy. 236232


I really like the trailer plug light. It is the perfect addition to my after market back up camera I installed. It makes backing up to my trailer so much easier in the dark, and its makes backing out of parking spaces in parking lots much safer. My only suggestion would be to replace the bulb with a LED one of the same or brighter luminosity.

I have used the Light Buster for many years. I drive an F350 extended cab with an 8 ft box and plow snow with it. I can see what is behind my truck at night. Thank you! Very fast shipping! 232679

Very bright works well, better than the reverse lights alone. It could be improved if the beam was more wide spread. Used on a 2013 F150. 346820

  • Will Peak Wireless Backup Camera Work Well in the Dark
  • In low-light situations, the Peak back up camera, # PKC0RB, will have that dark, washed out grainy sort of picture displayed on the monitor and probably will not be as useful as you need it to be. However, you do not have to get a camera system with night vision to be able to see with a back up camera. You could use a backup light like # C8020. It fits in a 7-Way trailer connector and will power on when you place the vehicle in reverse. The extra light will make the image displayed...

  • Hitch Light Options for a 2010 Dodge Ram
  • The Ball Mount Hitch Light, part # CR-607, should work on your vehicle if your ball mount has a drop. The light sits level with the shank of the ball mount, so if there is a drop, then the hitch or sway control bars should not be an issue. If you feel that the ball mount you have will interfere with the light, then we also carry a few lights that can use the 7-Way connector on your vehicle if you have one. The Light Buster Backup and Utility Light, part # C8020, is one option. There...

  • The lens of the Pilot Square Brake Light Hitch Cover, # CR-007, is red and would not work as a reverse light option. If you are looking to supplement your reverse lights, I have several other options that you may be interested in. If your vehicle has a 7-way trailer connector, then you could use the Blazer Light Buster Backup and Utility Light, # C8020. This light simply plugs into your 7-way trailer socket. Another option is the Pilot Ball Mount Hitch Light, # CR-607. This light...

  • Will Pilot Automotive Ball Mount Hitch Light # CR-607 Fir 2-Inch OEM Hitch on 2011 Toyota Tundra
  • The OEM hitch receivers on Toyota Tundras have bracing welded to the outside of the receiver tube that makes the actual outside dimension larger than on aftermarket hitches. In the case of their Pilot Automotive Ball Mount Hitch Light # CR-607 my contact at Pilot advised the square opening in the light will not clear this extra material on the hitch receiver.
