Topic: replacing a headlight on my cb750

[nowhere_fast]

I recently replaced the 7" headlight on my cb750 with a smaller light off of a cb175.  The bulb is a 12v 35/25w sealed bulb. It blew last night on my way home.. is it just a bad bulb or did it blow because the wattage was lower??

[tlbranth]

It's not because of the wattage

when i installed it, it was incredibly bright.. was this an indication that it was on its way out? haha or could i have possibly wired something wrong? i mean its only 3 wires i cant imagine something went wrong there

I have seen bulbs get brighter just before failure. Did low and high fail?

[nowhere_fast]

yeah the low failed then i used the high to get home and that failed as well after about 15 minutes

That is strange I would be looking for a loose connection at the plug at rear of bulb and the bullets then the Sw.every thing should be clean and tight. and coated with dielectric grease.

Sounds like either your voltage is way high or it's a 6 volt lamp

I have an extra tribar headlight (with blue jewel in the middle), and an extra visor (with blue jewel on top) I'll sell ya.
$50

the bulb itself is a 12v which is why i was really confused as to why it blew.. i mean it was off a really ratty cb175 so thats probably why haha.. its a 5" bulb which sucks because i wish i could just put a 5 3/4" bulb in, but nope, i had to do things the difficult way.. im gonna order a new one on ebay and cross my fingers.. if it blows again the giant 7" is going back on.. to my dismay.

Are you saying the seven " works OK
