Weird LAMPF problem

My '07 GS is giving me a LAMPF! Indication before start. After starting the engine, one or both headlights are inop. Then, so far, within a few seconds both lights illuminate and I don't have the warning until the bike is started again. Also this issue doesn't occur every start.

I'm on the road and thanfully I have HIDs installed as running lights but I can't use them at night.

Ideas anyone?

Very likely one of your headlight bulbs is loose and the connector is not making good contact.

Or the filament is broken, but still barely touching. If that is the case you will likely see the lights go off and on as you hit largish bumps.

Or your HID ballasts have changed just enough to confuse the system. Not unknown. Can you turn the running lights off and if you can does the problem still occur?

No ballasts on the H7 bulbs. It's odd both lights do this in unison if a bulb is loose.

If the low beam has an issue the high beam can sometimes be effected, or both are loose, but that would be odd.

The Hid running light solenoid gets its signal from the high beam wire. The problem occurs regardless if I have the Hid switch on or off. The Hid will illuminate even if the the high beam isn't working. But remember, so far the low and high beam lights will work even thought they make take a few seconds to illuminate after engine start.

I'm with you on this...

That's the first thing I'd check - and use dielectric grease on the contacts...

Dielectric grease may be worth a try.

Happened to my '07 too. Then one day after a month of such behavior (the vibration used to fix it) the little bulb, decided to die.
Simple really.
