LED headlight eliminate need for EB Headlight adapter?

I've recently put LED headlights in:
CSP H11 880 9005 9006 H1 H3 H7 LED Headlight bulbs 50W 8000lm 6500k lights Kit

The bike also already had the Easter Beaver H4 Dual Headlight Relay Kit installed.
With the low draw of the LED headlights, would the relay kit really still be needed?

Thanks!

Possibly

You cut the continuous power draw 50% but still would have 4 amps going through the start switch if you remove the relay harness. I did a similar install and did not buy and install the relay harness. My riding buddy decided to install the relay harness plus a kill switch for one head light because he decided not to install LED and stuck with OEM halogen lights drawing 4 amps each. Greywolf seemed to always advise using a relay because it will protect the start switch. You can use an alternative start sequence so the headlight power only runs through the start switch one time: turn on the Run switch, depress the Start switch (this kills power to the lights), turn on the ignition key, then when you engage the clutch by pulling the handle to the bar, the engine will start and you will release the Start switch as usual. Normally the lights go on when you turn on the ignition switch, they go out when you press the start switch, and they come back on when you release the start switch. In theory, reducing the number of times you power the headlights on and off by 50% should decrease the "load" on the start switch and so should reducing the power in the light circuit by 50% as you have already done. The relay harness is best so I'd likely not remove it.

The answer is "yes", running the EB headlight relay kit with LED headlights. Even though LED are consuming much less power than Halogen, there is still a good size inrush of current when they turn on and while running. Is your V Strom less likely to develop the well known starter switch problems if you run LED lights from new? Yes, I would say it is. But it isn't immune from it. The EB headlight relay kit all but eliminates problems of headlight circuits.

Be warned reducing the electrical load will put more heat into your stator if you have the original regulator, this could shorten the life of the stator.

Wouldn't there be more heat in the regulator, not the stator, since the regulator pulls maximum wattage from the stator at all times without a regulator upgrade? The regulator would have more energy to dissipate and would become hotter with the LED lights.
