| WMRRA Qualifier  Joined: Jan 2010 From: Marysville Washington I Ride: 1998 GSXR 750 |  dead headlights, and two weeks old?? oh I was irritated today............ Last night on way home from work coming down my driveway, headlights cutoff I reached over smacked the lense and they came back on ... While the bike was warming up a few days ago............ They cutoff and came back on, all by themselves. Today, while warming the bike up to get to work, they came on like normal... Then cutoff and stayed off... I have voltage going to the plug. Removed headlights. They look Ok............ But ring when shaken. They are H4's and are a couple weeks old. Kinda odd for both headlights to take a shit at the same time............ GF had to give me a ride to work............ I'm thinking I have a short some where. Any ideas where to look? |

EDIT: I forgot the word Super, what was going on is your filament was bouncing around and just rewelded itself as it made contact with the other half of the circuit, but eventually that will come to an end too. You can always check to see if the bulb is "open" if that is a volt ohm meter you used to check the voltage Last edited by Suzuki Stevo; 02-07-2010 at 04:42 PM.. |

Did you touch the class of the bulb with your bare hand??????? If so, the oils on your skin heat up and burn. That causes the bulb to fail |

Now there is nothing. The past week I have also noticed the the lights have been pulsating. A lot more noticeable when hi beams were on............ . Just going to have to ring out the wires and go from there............ | |

| Superbiker Joined: Jun 2006 From: urmommas house | Check not only voltage but resistance across the socket. Contrary to popular belief you can have voltage with too much resistance for current to flow, espicially with electronics. I have run into this soo many times at work with circuit boards reading 0 or 4 to 20ma loops. Its the one damn time when a fluke meter is useless, you need a knopps or other sinilar ciol style meter Ideal also has a decent one but not worth the money. When you have a meter jiggle wires and see what happens. |

| WMRRA Qualifier Joined: Jan 2010 From: Marysville Washington I Ride: 1998 GSXR 750 | ok so i remove the left fairing and air intake tube. expose the wiring harness so that it is easy to get to. prior to doing this, I double checked to make sure that I still had no power in on the high beam side, and that I had no working lights blah, blah blah.......... so after the fairings are removed I check everything again. I now have power every where, lights work and all of that good stuff. I just need to replace the socket pig tails since there was a short there and the plastic was melted. I am not seeing where the loss of ground was. But that has to be where the issue is. $10 says that I get this put back together and the lights still dont work. the good is that I now have headlight for a very damn long time!! lmfao |

I dont own one... <-----Fail | I am assuming you had a bare bulb when you put it in, I am also making the assumption it was a halogen bulb.... If you touched the glass at all with your bare fingers the bulb will blow FAST. The natural oils on your hands will super heat causing the bulb to run hot resulting in the bulb burning out more quickly if not just plain exploding...Anyway, thats what I bet happened... (This info coming from my 7 years of lighting training and work in that field.) Trying not to just blow smoke out my ass.. I hope all this helps out. |

| Training Wheels  Joined: Jan 2010 From: Lebanon, Oregon I Ride: DR650 & CB250 Adventure bike | Check the ground also Sometimes, the ground for the headlight will get corroded or rusty. Clean it up and put some dielectric grease to keep rust away. Been there, done that. Dave |
