hey guys,
my rear tail light keeps blowing. the parking light, so not the light that comes on when you hit the brake. it has done it since i bought the bike a jan of this year. some times it blows them in a day or maybe a week or a month. kinda random, no pattern.

any ideas, i plan to do an investigation tomorrow, so i would love some input on where to start. im currently thinking that there is a loose connection creating heat and burning out the filament.

 

It's odd that it's the same filament.
No problems with any other bulbs?
I would start with checking that the mounting is not loose and causing the bulb to rattle around.
It's worth checking the voltage through the rev range, but I doubt it's a factor.
Maybe try one of these.

But that's not really fixing the problem.

 

U could always wack on a edge tail light, u wont get that problem with led's. But is not a cheap fix thats 4 sure.

 

U sure it's not the front tail light

 

thanks neil, i had a look to day at my bike, and as far as i can tell, it must just be the vibration or bumps that break the filament. after having a look at the link you posted, i consulted ebay and came up with this, http://cgi.ebay.com.au/2-X-24-LED-Ca...3A1%7C294%3A50
so hopefully this solves the problems.

 

Maybe that's it but I have never heard of this being a problem on any bike, dirt or otherwise.
And they all basically use the same bulbs.
In 3 years of abuse, I've never popped a bulb.
Have you got access to a multimeter?
I would certainly be checking a few things first.
Good luck and let us know if you find anything.

 

i did have a multimeter, but it died in the line of duty when i was checking the volts, gee...i never new my bike was putting out 73volts, then i found the frayed wire going to the probe, so ill have a another one during week, but for 12buck i though it would be a good place to start and i get 2 (the leds i bought off eBay). i also thought that if im getting a volt spike, it cant be very often as 2 globes ago, that globe lasted 2months(if that makes sence).

 

Seems to be a lot of cheap unsafe electrical components making the rounds these days. Someone on the forum here just lately had a problem with fuses, which could ultimately lead to a fire. Make sure your buying good stuff from a good supplier.
