I run Custom Dynamics LEDs all the way around my 05 Heritage, I also run their Smart Signal Stabilizer w the Smart Triple Play. I'm not a fan of but run Rivco's Headlight bulb and their passing lamp LEDs. The headlight is fine on low beam but gets washed out on High, the passing lamps are perfect.

I wanted to let you know I've never experienced any issues with the bulb or bulbs shutting down. But perhaps my load equalizer is the reason why. I'm not an electrical guy but I just wanted to share my experience.

 

I run Sealight (Amazon) bulbs on all 3 of my bikes, and all of my friends bike, never had any issues with them.

 

I looked at Sealight on Amazon and notice that they say: "SEALIGHT H4 9003 LED motorcycle bulb can fit 99% vehicles without CANbus adapter: but for some vehicles, computer system may be sensitive and send error message for any aftermarket bulbs. To solve the issue, an additional CANbus Decoder is needed to make the bulb perform well."

Does yours have the adapter?

When I add an inline resistor, the problem is solved with my bike. However, the resistor I got is quite large (physical dimensions) and although I can fit it in the headlight housing, it worries be because it gets extremely hot.
