Ninja 250. I've gone through 3 light globes just this week. What could be wrong?

My 55kw busted so I replaced with a 100kw which seemed like a big no no. Few days the 100kw burnt out and almost popped. Replaced it back to a 55kw and not long till it busted as well. About to ride home in the dark and all I've got spare is another 100kw which I will hav to use for now.

What is going on?

Use your high beam to get home (although you're probably already there), and replace the bulb with a stock bulb.

Sounds like you have a short somewhere.... I'd start by inspecting the wires at the headlight plug and trace the wires back. All of Ghost's recommendation are good too...

...What is lus?
Damn sticky keyboard!... I meant plugs ;D

'H7' refers to the size and configuration of the bulb, so any H7 bulb will fit on a H7 socket. However not all H7 bulbs are the same. Some bulb makers will make bulbs with the same name but applications can be different. I would try to find an H7 bulb designed for a motorcycle and see how it holds up. If it blows too, then start checking for a short near or inside the plug . To check the fuse and relays, you will have to remove the seat. The fuse box and relay are underneath. Your owners manual should be able to help.

Ewwww.

I wouldn't use anything but the lamps that are suited.

Lamps break because of, Over current, over voltage, usage (natural life), excessive vibration.

I've replaced lamps in industrial/commercial/residential settings that will blow a week later, then change them and they'll last 2 years.

I would start with checking voltage and current while running the bike and go from there I guess.

Checking voltage is going to be easy - a $10 multimeter will do that, but checking amps is going to be a different story.... For now, I agree, check voltage, get a replacement bulb from either your local dealer or Motorcycle Parts, Motorcycle Accessories or similar and see how that works.

Or...

You can put in an HID conversion kit.... :D

While installing thе bulbs just mаkе sure thаt all electrical connectors аrе properly joined tο metal connectors οn thе base οf thе headlight bulbs, otherwise іt іѕ simple tο gеt a small circuit аnd blow thе bulb.Check alternator for not proving a voltage more than maximum limit..Also touching the glass portion of a headlight bulb will leave oils on the glass.this oil on the glass super-heats, causing the glass to break.I am sure you will not realize this but it happens..
