Head Light bulbs keep blowing?

[clu55ter]

Hi I have a peugeot Trekker 100cc on a Y plate and I commute to and back from work 30miles round trip. Ive had it since end of August but in the last two weeks my parking light and head light bulbs have blown twice, any ideas on what might be causing this? cheers

vibrations , use halogen bulbs

Convert to LED for the parking bulb, Try better quality main bulb.
Vibration is the main culprit.

Sounds more to me like failing Regulator thats popping the bulbs!

Peugeots are known for this fault.

I had this problem on my gz125.....except i've been through about 5/6 bulbs since i got the bike.

I tried to get a halogen bulb but they don't have fittings to suit my bike (my wires will withstand the current draw anyway)

The weird thing is, the only part that has blown is the low beam (parking light is a seperate bulb) but high beam remains unhurt, except one.

I went to the bike shop to get a new bulb and it was getting kinda dull so i fitted it in the carpark there and then. Got home and realised my bulb wasn't on, and it had gone all white and burnt in some places.

Was this a faulty bulb or just one of them things?

But, the bulb im using now was one that popped a while ago, every so often the low beam would start working and now it works all the time..maybe it resoldered itself

It'll be a loose connection somewhere. The vibrations will be making/ breaking the connection fast enough for the repeated on-off to make the bulb blow. This seems to be a recurent problem on 125 4-poke singles as they're always revving their nuts off. An inner tube acquired from a bicycle shop at the end of a day (should get it for free) cut up and put into various joints may help protect the light fitting from vibration too.

i'm in the same boat as you clu55ter, the vibrations blow my low beam headlight frequently, once it happened at night, and a car flashed and tooted his horn, (which I appreciated as I hadn't noticed [residential area with streetlights etc]), so I switch to full beam which was my safest option, and the guy starts waving the V's, honestly, don't they realise that our bikes are weak and not immune from vibrations?!
