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?

What type bulb are you replacing the OEM bulb with? Are the lus installed correctly?
Have you tried checking the;
Headlight Fuse (10 A)
Dimmer Switch
Headlight Relay

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...

I got the bulb from the car accessories store. Its h7 bulb. Dats all i know about them. Is this bad for the bike or only the bulbs i replace them with

What is lus? I havent checked any of these. Dont know where to look or what to look for?

...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.

Damn sticky keyboard!....

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....

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..
