- C7493RTM

Good price, good product. After 1 year light is just like it was the day I installed it. The old trailer lights bulbs were always coming loose and with this LED unit everything is working all the time. I strongly recommend this product, it's the best upgrade available.

- C7493RTM

Nice, bright lights! Each trailer is easy to work with, with great videos, even advice and awesome customer service. Lights were easy to install, and don’t shatter when they get wet.

- C7493RTM

Great customer service...I was able to track my order from beginning to delivery and etrailer provided e-mails to ensure I received my order. Thanks for excellent service...I will shop and purchase again from etrailer.

- C7493RTM

The parts that were delivered were exactly what I expected, they fit very well & seem to be made to last many years. With one exception, the bushings with the 1/2" bore fit loose within the eye of the leaf spring. The pricing was very competitive. Delivery was prompt and on time.

Ask the Experts about this Blazer Trailer Lights

  • Can Blazer C7483RTM and C7493RTM LED Trailer Lamps Be Mounted From The Side
    Both the Blazer # C7493RTM for the passenger side and # C7483RTM for the driver's side can be mounted using the slots molded into the rear or the inboard side of the lamp housing. I've provided photos of both lamps showing the slots in the side of the lamps. The photos we use are taken in-house using the actual parts. I've also linked to an install video that you might find helpful.

  • Troubleshooting Blazer Trailer Tail Light C7493RTM That Stopped Working
    First check to make sure the light is grounded properly. That is typically what causes a trailer light to stop working. Especially when the light is an LED that doesn't normally burn out. The light # C7493RTM that you referenced has a sealed lens that does not allow you to get into it. Plus the LED light inside it is not like a standard bulb that is easily replaced. Try improving the ground first. That will most likely fix the problem. I attached a couple help articles on troubleshooting...

  • Replacement Blazer Driver Side LED Trailer Tail Light Assembly
    The Blazer Trailer Tail Light # C7483RTM referenced in your question is the only driver side assembly from Blazer that we currently have available. The pictures of your existing unit did not come through for some reason so I'm not sure exactly what your assemblies look like, however the lens on this light does feature individual circular patterns for the LEDs within the large outer circle. I have attached an image to better clarify this. I have also attached an installation video that...

  • Troubleshooting Trailer Running Light Circuit Not Functioning
    Try connecting a known working 12 volt power source to the brown wires of the Blazer LED Trailer Tail Light # C7493RTM that you referenced. This is the running light circuit. If the light does not come on then the assembly is the problem but if it does then you know it's the wiring that runs to the assemblies. You should also verify that the white wire is connected to a solid ground too as that can sometimes cause lights not to work.

  • Recommended Blazer LED Submersible Boat Trailer Tail Lights Installation
    For the Blazer Trailer lights, you will want the Blazer Trailer Tail Light - 6 Function - LED - Submersible - 7 Diodes # C7493RTM for the passenger side and the Blazer Trailer Tail Light - 7 Function - LED - Submersible - 9 Diodes # C7483RTM for the driver's side. That 7th function and the extra diodes are for the license plate light. These two parts are designed to be a pair.

  • 2012 Jeep Liberty Headlights Cause My Trailer Turn Signals and Brake Lights to Fail
    It sounds like there may be a couple of issues going on here. First, It is very common for LED lights like # C7493RTM & # C7483RTM to remain on very dimly whenever the trailer is connected to a vehicle, even if the ignition is turned off. The only solution is to disconnect your trailer when you will be parked for extended periods. Now let's address the bigger issue. When turning on the vehicle's headlights causes one or more of the trailer lights to stop working the number one culprit...

  • Is Bulb of Blazer Trailer Tail Light # C7493RTM Replaceable
    The Blazer Trailer Tail Light # C7493RTM is an LED assembly which means that the bulb isn't replaceable, but due to how long LEDs last you really wouldn't have to worry about that. Unlike incandescent bulbs LEDs last a very long time so they aren't designed to be replaced.

  • Is it Okay to Drill Hole in Back of Optronics Light as Means for Wires to Exit?
    You could drill a small hole in Optronics Tail Light # STL8RB, though it would almost certainly void the warranty. I may have a better solution for you with Blazer Tail Light # C7493RTM. This light is also a red, square, LED light with mounting studs 2" apart on center. However, the wires in the rear of this light exit in the middle so there would be no need for you to drill any holes or make modifications. I've added a photo of the back of this light so you can see where the wires...

  • Troubleshooting Trailer Wiring Where Blinkers Only Work with Headlights Off
    Sounds like your issue is that you have the running light circuit wiring ran to the brighter stop/turn illumination circuit of the lighting. So what you'd want to do is reverse the wiring of the two circuits. Either at the connector or at the lights (whichever is easiest) and you'd have the issue handled!

  • Operation of Blazer LED Tail Lights
    Thank you for the details. I reached out to my contact at Blazer International to ask about the Blazer Trailer Tail Light - 6 Function - LED - Submersible - 7 Diodes - Red Lens - Passenger Side # C7493RTM you referred to. I confirmed with them that 2 LED's on is that proper function for running lights and all the LEDs for turn signals. Based on the information you gave, your light is working properly.

  • Recommended 24 Volt Compatible Trailer Lights for Utility Truck
    We do have some 24 Volt lights, but the Blazer Trailer Tail Light - 6 Function - LED - Submersible # C7493RTM is only for 12 Volt systems. Here are some 24 Volt options: Miro-Flex LED Trailer Stop/Turn/Tail Light - 12 Diode, 24 Volts - 4" Round - Red # STL23R24B Miro-Flex LED Trailer Parking/Turn Signal - 16 Diode, 24 Volts - 4" Round - Amber # STL23A24B

  • Troubleshooting Trailer Lighting That All Blinks When the Right Turn Signal is Applied
    Sounds like you have the running light circuit of your trailer wiring shorted out or ran to the right turn signal circuit which is causing all of the lights to blink when that circuit is activated. I'd go over all of the wiring of the trailer and clean up any connections or exposed wire as needed.

  • Does GloLight LED Combination Trailer Tail Light STL161RLB Have Built In Side Marker Light?
    The GloLight LED Combination Trailer Tail Light - 5 Function - Submersible - 39 Diodes - Driver Side # STL161RLB you were looking at does not have a built in side marker light, so you would need to add a side marker light using # 328-K-52. Another option would be to use the Blazer LED Trailer Tail Light - Submersible - 6 Function - 7 Diodes - Red Lens - Passenger Side # C7493RTM and Driver Side # C7483RTM instead which do have the built in side marker lights. I included videos of...

  • Troubleshooting Peterson Tail Lights on Boat Trailer That Keep Burning Out
    It really all depends on what trailer light kit you have installed on your boat trailer. Some kits are designed to withstand submersion and other kits aren't. If you can let me know what kit is on your trailer (not just the type of bulbs you use) I can help you determine if it is submersible (granted we carry it). Another thing to note is that you need to make sure your trailer wiring is unplugged before backing the trailer into the water. Even if your lights are submersible, if you...

  • Square Trailer Taillight Recommendation that Can have Longer Mounting Studs Used
    You'll want the taillight part # C7493RTM if you are wanting a light that allows you to pick the length of the mounting hardware you'd need. There's no way to replace the studs of the light you mentioned. I attached an install video for you to check out as well.

  • Interchangeability of Trailer Taillights Left and Right Assemblies
    I can see the possibility of 2 issues presenting themselves. First would be the mounting brackets. If they are offset the bracket may not be able to fit your mount. Or if the lights are only designed to slide on one direction like the Blazer LED Trailer Tail Lights # C7483RTM and # C7493RTM. If the bolts were to loosen the light could slide off the bolts and be dragged by the wiring. Second is if the lights have a weep hole to release any water that would accumulate in the lens....
