Blowing light bulbs

Discussion in 'Technical and Troubleshooting Torque' started by sonja, Aug 14, 2006.

  1. I have just replaced my tail/brake light for about the 4th time in less than 18 months.

    A very kind driver let me know while we were in heavy traffic (for Canberra).

    Anyone got any ideas why this happens?

  2. On the GPX ?

    Not sure mate, i would imagine something is short circuiting it out. Never had that problem when i was on my GPX.
  3. I knew it wasn't normal.

    I rekon it's probably shoddy electrics or summat, but I can't be sure. I'm just getting a little tired of it, but don't want to be without her for more than a few hours again. It's all very annoying.

  4. how have you been handling the globes? were there dirty big fingerprints on them? i've heard/read somehwere that fingerprints create 'hotspots' and thus prone to blow up more frequently...

    is somebody able to confirm this?
  5. That only happens with Halogen globes as far as I know.
  6. I never had any problem with my tail/brake bulb so far since I got my bike 18 months ago.
  7. Get the charge rate checked out as even with the 20K a year I do I only go through one set.
  8. Concur with the charge rate check. I had a similar problem with gsx400 a few years ago (in canberra as it happens). Burnt out a few regulators for whatever reason, I went through 3 in the end before I sold the bike. Tell tale sign is if you look at the headlight while giving a rev if the light intensity goes up and down with revs then that could be it.
  9. Thanks for the advice everyone.
  10. Check for water ingress
  11. That'll take a bit for the electrics, but the area where the bulb is was clean and dry.

    I'll have to see what I can pull off to look at the wiring when i get home.
  12. If it's only tail lights, it probably won't be voltage regulator. It's probably a vibration issue, so I'd check tail light mountings for tightness or damaged rubbers, and check that there's not something loose at the rear of teh bike banging around causing a vibration. Higher quality bulbs may help too, try some Hellas.
    If that all checks out, maybe time for a couple of LED bulbs.

    Regards, Andrew.
  13. I'll see what I can dig up.

    As to the LEDs: The brighter the better! :grin:
  14. Bear inmind it could be water in the thing.

    I blew 3 rear lights in the car before I noticed on cold mornings that condensation was inside the brake light...

    the black external seal had a small split in it that I'd never noticed before, $5 later it was all fixed.

    Just check for that in the morning (should be pretty easy)
