Delay going from dim to bright headlights

Post by Jag39 » Mon Jan 08, 2018 7:04 am



I have been experiencing a delay of about 4 seconds, when going from dim to bright headlights. During that 4 seconds, I have no headlights at all. No problem going from bright to dim, though. Wondered if anyone had any ideas on this. Bought it used about 6 months ago, and have had the problem since that time, so don't know if this is the result of previous owner installing something special or not.

Easiest to check is to swap the high and low beam relays.If it follows the relay,replace it.If it's the same,remove the headlight and look for aftermarket wiring....a modulator perhaps that has failed?

Ok, I'll give that a try when I get back to the shop. Appreciate the reply.

Took me a while to get back to the bike, but did find the problem. Relays were good, actually new ones from GoldwingDocs, that I replaced not long ago. Found a Path Blazer Modulator behind the head lights. Traced the cord, but it wasn't even plugged in. Not even sure where it is supposed to plug, and very strange looking plug. Looks like a light bulb on the plug end. Anyway, unplugged it and reconnected the original plugs, and everything just hunky dory now.

Thanks again for the tip.

You bet! GoldwingDocs has been my go to place for things like changing belts, reverse issues, etc. Lots of folks on here with answers that have saved me a lot of time.

I'm betting that the "light bulb" is actually the light sensor that triggers the modulator to shut off, or turn on. Try plugging it back in and shine a bright light into it and see if the headlights modulate.

Even if the light bulb is the light sensor I suspect the unit is defective. I assume if the sensor was behind the panel, it is sitting in darkness, so the modulator should have been disabled and it should switch between lo and hi immediately, the fact it was delayed would indicate to me that it is probably defective. I have a modulator on my wing and love it, but have never noticed any delay when switching between Lo & Hi.
