The Custom LED 1.85" Universal Round LED Clusters feature 18 ultra bright running light LEDs in your color of choice, and 16 ultra bright turn/brake LEDs in either red or yellow. The LEDs and ColorChange Technology is tightly packed on the PCB for the tightest power density possible. The total thickness from the top of the LEDs to the bottom of the circuit board is only ~0.45". These LED clusters are amazingly bright!
With a simple three-wire configuration, the clusters have a Run input (primary LEDs on), a Turn or Brake input (secondary LEDs on), and a common ground. The on-board ColorChange technology will automatically shut-off the Primary LEDs anytime that the Secondary LEDs come on. This way there is no color-mixing, and the turn or brake indication is a pure color and distinguishable.
Example: a White primary/Yellow secondary setup would be bright white for running light, and would alternate between white and yellow when a turn signal is on.
For Run, Brake AND Turn function, add our 4-wire Conversion Packs, and now you have Run (dim primary), Brake (bright primary), and Turns (bright secondary). You would want to choose the RED PRIMARY/YELLOW SECONDARY configuration for this setup.
We have a large collection of all Custom LED product videos on the Custom LED YouTube Channel.
The videos in this playlist below are a collection of user-submitted and original videos related to our 1.85" Round Clusters.
The Custom LED 1.85" Round Clusters come as shown in the pictures. There is no mounting hardware or enclosures provided. Mounting can be achieved simply with hot-glue, or double sided tape. Care must be taken to prevent shorting the exposed solder points on the back of the PCB. The Clusters are not waterproof, so they must be enclosed in a suitable enclosure. As mentioned above, the 1.85" dimension is similar to that of an MR16 lamp which is commonly used in aftermarket turn signal housings.
Wiring the Round Clusters is as simple as any 3-wire setup:
- Red wire: Run +12V (illuminates the Primary LEDs)
- White wire: Turn or Brake +12V (illuminates the Secondary LEDs, and shuts off the Primary LEDs)
- Black wire: Ground
As with any LED blinker modifications, additional accessories may be required to maintain the normal blink rate after removing incandescent blinkers, and installing LED blinkers. The correct solutions to these issues are covered in our Frequent Questions section of our website.

- stock lights
- turning signal
- hotbodies kit
The product itself was more than adequate as a replacement for my old LED’s, the gentlemen I spoke with directed me to get the 3 wire conversion as well as the LED’s. The service was fantastic the shipping was even better being from Canada I’m not used to this type of service I would highly recommend these LED’s as well as this company itself!
Replacing LED cluster
The product was perfect for a replace cluster I had on my UTV that was not working. Thanks for the rapid response and quick shipment.
1.85" round LED cluster
Brightness is amazing and makes a world of difference on my GSXR 750. Great LED!!!!
Good investment for safe style
Definitely brightened up the undertail on my RC51. Guys I ride with complained they couldn't see what I was doing (braking/turning) prior to the conversion. Now, things are nice and bright back there and I feel much safer, especially when riding alone and trusting cars behind me to react to what I signal. I highly recommend these lights! Was a fairly simple conversion for the Mototeck undertail on an '02 RC51. Thanks Custom LED!
Quick and good quality
Very quick shipping
Brighter, safer brake lights
Bought these for my RC51 SP2 with the hotbodies undertail. Install was easy just had to pop out the lens from the hotbodies kit using a heat gun, then I used a dremel to cut out the lights from the lens and then I used a silicone sealant to glue in the custom led lights into the housing. Overall it was pretty easy to do and the results are incredible. Very happy I went with custom LED.
Lights, relay, wires...oh my!
I bought the lights, 3-4 wire adapter and flasher relay for my newly acquired Honda Rc51. I can’t begin to tell you how bright these lights are. The wiring instructions were spot on as well. I opted to solder and heat shrink my lights into the harness versus the crimp connectors, but I am sure they would work fine. I really don’t have any issues with the product, the instructions, or the quality. Couldn’t ask for anything more. I’d recommend this product to anybody looking for an upgrade to their undertail assembly. I’m very happy with the outcome!
Absolutely best upgrade
When I tell you it was worth every penny it definitely was!! I literally feel that much safer from my back knowing it’s much brighter especially during the day time! The old Stock LEDs were barely visible during the day time , especially the blinkers, now these are visible at ALL times! I completely recommend for anyone that cares about their life on your bike...
The new leds are great. really nice and bright.
Nice and bright
Fit nice in the hotbodies undertail kit for my 2002 gsxr 600 turning signal and brake light are very bright compared to stock lights that came with the hotbodies kit
Loved it!!!!! So bright!!!!!!!
HotBodies UnderTail LED’s
Although, I have yet to install these LED’s there area several great points to be made thus far. First, “MADE IN USA”! The entire ordering process was incredibly simple, and the website provides plenty of information for questions. Packaging and shipping was fantastic with detailed installation instructions. The craftsmanship of the LED’s is leaps and bounds above the ones that will be replaced. With the increased number of diodes, the safety margin will certainly be increased. Overall, quite pleased with the purchase and look forward to installing them on my RC51 project.
LED upgrade for hotbodies undertail
I bought these to upgrade the factory taillights on a hotbodies under tail and the they work great. Now my running lights, brake lights and turn signals are all in one sleek little round led light. And they are nice and bright. Highly recommend
Bought these to upgrade my 01 GSXR hotbodies undertail
My hot bodies undertail lights were so dim, that I was uncomfortable riding especially at night. They were unsafe and potentially illegal. These clusters along with blaster-x module, was such a great investment. Now my LEDs are so much brighter and they flash thanks to the blaster-x. CustomLED makes some top of the line, high quality, and functional products. I'm impressed with what this company does and they are highly recommended by me! If it wasn't for this company, I would still be riding unsafe with those dim led tail lights. Thank you CustomLED!!
I ordered two 1.85" round clusters to replace the taillights in my hotbodies und
I ordered two 1.85" round clusters to replace the taillights in my hotbodies undertail for my cbr 600 f4i. They were a vast improvement! Very high quality stuff. I wish you guys sold an external blaster x controller so I could wire that to my clusters!
