Hi

My bike (Iron 883) got issue on the headlamp. I believe the headlight is one of the "daymaker" ones. It has four bulbs (LED?). Three for low beam and all four for high beam. What happened is:

1. starting up in the morning, low beam (3) works, switch button to high beam on, the 4th bulb blinks for 0.00001 second then all bulbs off.
2. riding for 30 mins + at low beam, high beam indicator goes on by itself, funny is it is gradually turning on. The indicator has two parts, the beam part and lamp part. only the lamp part turns blue first, then after another 10mins riding, the beam part turns on too.
3. once i get to work place, after 1 hour riding, high beam indicator is full blue on all the time even at low beam switch; high beam can work now. switch on, all four bulbs on, switch back to low beam, 3 bulbs on.

any idea of this?

the battery is new, instant engine start every morning.

 

Lost me there,,?

 

yea, this is really funny. It's just Iron 883 factory gauge/indicators. Don't know if you have one. If you look really careful at it, you will find the high beam indicator is the shape of "a little lamp shooting beams". When indicator is on, you will see a blue lamp icon shooting blue beams. So it has two parts, beam part and lamp (cone shape) part. My issue is, indicator will be on when it is not supposed to. And when it turns on itself, I see the lamp shape part turns blue first, the beam part is still off. Then after riding for a while, the beam part turns on.

 

Short in the bulb, try replacing it with a standard bulb first to isolate the problem to the bulb or wiring.

 

Sounds like you could have a bad ground.
