any one good with bike electronics or rather lights???

[richyt]

i decided to get a set of osram night breaker plus bulbs for my ER5 headlight and both blew with in 20 yards but fuse was undamaged and yet w the old bulb still works with out a problem
any ideas?????

12V 55W H7 types I assume?
They shouldnt fail that soon of course but guesses are

Bad batch or cheap crap copies sold as original Osram.
Bad connectors, rough handling.
Not handling the bulbs with clean cloth so oily skin leaves residue and 'hot spot'

Over voltage is a possibility, but this will usually blow other bulbs as well as cooking the battery.

ER-5 is a H4 bulb I belive.

I'd hazard a guess they've been bounced or dropped at some point during shipping...or as WD says you've touched the glass on install?

Cheap shite snide bulbs with incorrect gas seal take about 20 seconds to overheat and pop.
From where did you obtain these specimens. ?

got one of those in my bandit, has a similar issue, not just with the nighbreaker though.

along side the normal checking of the connector, check the insulationof the wire for the side light, my issues tracked back to current sinking thought for some reason (age maybe)

What do the failed bulbs look like?
got a pic?
If they're kind of milky inside, that usually suggests they leaked
and as they're new, may indicate a batch batch or cheap shit copy
if they havent been knocked about a bit
