Kz750 LED headlight install question

Good afternoon, I have a question about the wiring and whatnot with my 1981 KZ750(4) LTD. Today I changed the headlight to an LED one and now the high beam indicator light stays dimly lit at all times, you can definitely tell it gets brighter when the high beams are actually on but when on low beams there is a definite light coming out of it. The headlight is a Holley Retrobright 5700K H4 plug and play I bought. The Holley website has them pulling 25w on low and 30 on high. Also putting out 2000LM on low and 3000 on high.
Edit: I just looked up the halogen, it pulled 45w on low and 55 on high. 
I love the new headlight and it’s actually really tasteful for an older bike not like some Amazon special got thrown in there, so I really want to make it work 100 percent. 
It’s not a great picture but you can definitely see there is some light coming from behind the high beam marker. Those have also been LED swapped Im not sure if that matters or not since it worked perfectly fine when I had the Sylvania Halogen in there.

Delete......Wookie beat me to it.

Looks like returning to the halogen bulb is going to be the easiest thing to do. Definitely recommend the Holley Retrobright to anyone who is looking for a quality Led that’s plug and play with these bikes.

The easiest thing is to put the incandescent bulb back in the warning light (which should sort the issue) and keep the upgraded headlight

The 750H bikes have a "Reserve Lighting Device", which monitors the headlamp circuit and switches between high and low, if either filament burns out.  

I wonder if this module isn't seeing the proper level of resistance, and now thinks that one of the filaments is burned out?  You may have to add a resistor, or switch to a higher resistance bulb.  

 I agree with Nessism, like the turn signals on most newer cars, when the circuit doesn't sense s certain amount of resistance (ex. filament bulb being burnt) then you have hyper blinkers, when using lower wattage LED, there's much less pull thus telling reserve system somethings up.

there's much less pull thus telling reserve system somethings up. Happy to stand corrected but I believe the "reserve lighting" unit senses a "ground" through the lamp so that when the bulb fails the unit loses the ground on the sensor wire as a blown bulb is an "open circuit", I don't think it's resistance sensitive

When I installed LED 1157 bulbs in the rear of my ol 2003 Sable, I had to install a 5 ohm resistor in line with each of the two rear lamps, otherwise dreaded hyper blink

I guess "modern" is open to interpretation. I am assuming you are talking about a Mercury Sable (which was originally born in 1985 and revamped several times) and I did say "most". Don't forget I am in Europe so base such comments on what I am familiar with, the likes of Volvo, Mercedes and VW by 2004 ish where already starting to move towards "can-bus" lightinging which uses a control module sending a hexadecimal coded voltage signal to the bulbs. This changes the brightness of a bulb by varying the "duty cycle" of the supplied voltage.

Gotta love engineers, who else would take a simple device like a light bulb and make it so it needs a computer to operate it. That's why my personal vehicles are old enough that they don't have computers.

Most of the systems on current vehicles (I am guessing some of the newest bikes also) use this technology (remember your HVAC fan having four positions and the radiator fan being fast/slow) everything now is infinitely variable by controlling "duty cycles" - one of the downsides is you can't test it with a multi-meter any more, now you need an oscilloscope. Some shock absorbers have a coil wound around their body so you can change the viscosity of the oil by changing the strength of the magnetic field depending on "mode" selected or driving conditions
