Headlight bulb keeps blowing after riding

What brand bulb are you using
I would check the wires in the bucket, there may be a cut on one of the wire causing a short. You can replace the wire harness to the bucket and see it that takes care of it.

These bulbs solved the problem in my K9... its been 9 months and so far spo good! :2thumbs:

Does your wiring harness have the 15 to 20 turn 1" diameter BLACK (ground) coil of wire in the headlight bucket.
On my "07" I think the coil of wire is used as an air core inductor to slow the in-rush of current through the bulb filiment when it's turned ON. This helps to save the bulb but the main reason is to protect the headlight driver circuit in the EHC module.
You could splice one IN if your harness doesn't already have it.
Check you battery voltage when you engine is near 2000 RPM for around 14 volts max. Your voltage regulator could be failing.

If the voltage regulator was over charging, would the lights be brighter. Probably a dumb question, but had to ask.
Yes, it would also blow the taillight as well. Let me state that differently... Yes, if the v/reg was out of the loop or was broken internally, you are going to get AC voltage, not converted to DC and balanced up to 14v at the bulbs. Now, it is more like 17v/19v and that ohm's conversion says a 12v bulb times 3w for the tail and 55w for the h/l bulb = Blown like a fuse.
Like installing a 6v bulb in a 12v system = Pops or burns out within seconds.
Keeped the black coil on the harness went for a 2hour ride and it blew again changed it on side of road it blew again when I got home after 2hours have had metre put ova it everything fine am now trying a Hella bulb longer life and have rubber mounted the headlight to the tree also noticed I have a blown left fork seal will fix that this weekend bulb seems good so far have also found the little screw that holds bulb in headlight was coming lose so used lock tight hope this works

The EHC monitors the H/L beam current and will switch to high beam when the low beam burns out and will flash the H/L indicator.

Hey Bro, I will be coming over end of January... my house is in Papakura.. if you are in the Auckland area I can bring some of these: [ame=http://www.amazon.com/PIAA-70456-Xtreme-White-Anti-vibration/dp/B000TK3U4O/]Amazon.com: PIAA 70456 Xtreme White Plus H4 Anti-vibration Bulb: Automotive[/ame]
Those are the ones I am using and after a year I am still in the first one.. :2thumbs:

The coil of black wire within the headlight bucket was one of the first attempts for BDM in preventing the headlight failure issues.
It was a VERY LAME attempt at creating what is known as a "Choke Coil", to slow the in rush of current during the initial energizing of the Low or High beams.
It did NOT work,..because that was not the issue behind the headlight failures!
Eventually BDM (NightTrain) located the true problem causing the headlight failure issue, and it was resolved with SB-1077.
Since the coil of wire really didn't help things, but didn't hurt things either, and due to the fact that BDM was mass producing a lot of parts. It took quite a while for BDM to use up all of these headlight harnesses with the black coil of wire on them!
At one time, you could order (2) headlight harnesses, and receive (1) with, and (1) without the coil of black wire on the harnesses. This really confused everyone!
..
But in all reality, it's NOT necessary!
You might want to check your Headlight Harness, at the JST Connector end, under the gas tank!
Sounds like there might be intermittent connection, or possible condensation within the JST connector itself, causing a shorting condition.
Also check the EHC Serial Connectors for secure connections.
These types of things happen most frequently and cause a whole lot of confusion.
Good luck and hope you find the issue!

had a similar issue that my light bulb blew out ever few weeks. I noticed that my rim from the headlight always losened up and hence the reflector and bulb were exposed to lots of vibration. Once I fixed that the rim remained firm in place I had no further problems.

Although this is an old thread, I wanted to clarify some "SHORTED" explanations.The coil of black wire within the headlight bucket was one of the first attempts for BDM in preventing the headlight failure issues.

Well, with that being said...
A connector or harness short condition upstream of the headlight bulb supplying power to the filiments will not cause the bulb filiment to burn out because the filiment is at the end of the circuit run, considered a LOAD, away from the power source.
A connector or harness short condition would affect that connector area or somewhere else back upstream to the next weakest point towards power source.
