I have led lights with a load equalizer that fixed the hyper flash. I then bought the converter to connect brake and turn signal lights together and the hyper flash came back? The service engine light is coming on, should I worry about it? Has anyone had this issue.
Thanks

 

You didn't include year/model info, & the requirements for a load resistor/equalizer can be different between CANBUS & non-CANBUS systems, but I'd remove the first load equalizer and see if it resolves the problem.

 

It’s a 09 Superglide. I will remove the stabilizer and see what happens. Thanks!

 

You probably cant have one converter in front of another. Custom dynamics make a convertor that will do both things you are trying to do.
