HI all. I just installed a cyclops led headlight in my 07. The beam pattern us actually pretty good, and it's stupid bright. Unfortunately the high beam causes a definite engine miss while on high beam. Low beam is fine. Not high.

Anybody know of a solution to kill what I'm assuming is rf interference?

 

What is the wattage or amps draw? You may be overloading the alternator.

 

The draw is 40w high, and 20 low. It's not a constant miss, nor is it at high or low speed. It appears random in nature.

 

Is this what you meant to say, and what exactly are you trying to say?

Anyway, I would research other alternative issues. Does your bike have a battery?

 

Sorry. Low beam is fine. It causes no issues. When you switch to high beam the bike develops a occasional miss.
Problem developed immediately after I replaced the bulb.

 

Just for the heck of it check that your battery terminals are tight and a good connection. I have had engine miss with a led and along with a few other things my battery connections were loose. I made too many changes at once to pin it to one thing unfortunately. Mine always was starting and charging but would miss fire. I really don't think the led was at fault though.

 

Check your battery then disable your LED. Does the miss go away? Im running a LED headlight and two axillary LED on high beam and dont have any issues.

 

Same here 2 work lights on high beam.

 

The beauty of LED systems is that they have a lot lower draw than most other more conventional bulb designs. 40w shouldn't challenge your electrical system whatsoever. However, did your Cyclops come with any kind of component for resistance, modulation, or otherwise? Do the directions show a direct hookup to the lighting power circuit, or is there anything else inserted into that circuit?

Only other advice I can offer is an old rule of thumb. When encountering a problem, go to the last thing you worked on, repaired, or replaced. Sometimes while doing an obvious task, you end up disturbing or damaging another element of the vehicle. Up at the headlight wiring on our bikes are a lot of other wires and such...ignition, etc. Go back and make sure you didn't pinch or make accidental contact with other wiring...especially the high beam circuit in your case.

 

You never answered this question!
