Dipped headlight bulb off!

[Brodie13]

I know this is a numpty question but just recently I thought my bike was blowing dipped head light bulbs (not main beam though?). Upon investigation it seems that the bulbs aren’t blowing but the wiring isn’t allowing the bulb to illuminate anymore? Any suggestions please to rectify this annoying issue as electrics aren’t my thing (obviously!!). Many thanks

Do you get the lampf warning on the dash?.
The only suggestion I have is to check the loom connections and give the wires a wiggle to see if the light comes on.

 

[Brodie13]

Thanks. Yes, got the Lampf warning

Then it's a blown bulb

if both main & dipped beam are still working, then it's your rear bulb has blown a filament

The curve ball is it will show a tail and stop when required DAMHIK

Then again if it's a LED tail unit lol

This is such a confusing post with more questions than answers ?? How have you checked it’s a wiring issue and not a bulb ? Is only the main beam illuminating but not the dipped ? Was the engine running when you did the wiring check or did you only have the ignition turned on ? Year of bike ? How long have you had this problem ? How did you check the bulbs ? You’d the words “blowing bulbs”,? so you’ve tried new bulbs, did they work briefly before blowing or not at all ?

That's why I asked if he got the lampf. I wondered if he'd been checking it without the engine running. Others have done this

Hi Niel It’s a 2009 GSA. I have tried two new dipped headlight H7 bulbs when engine is running and they haven’t illuminated or blown so I’m assuming a wiring issue? Happened the other week and has been fine for weeks beforehand? I will double check the rear brake light now…..

Brake light working….I’ll have a wiggle with the wiring! Thanks for everyone’s help

Have you taken the bulb out and checked both filaments? The bike has a function to run brake & tail light on one filament if one filament fails

 

[Brodie13]

Yep, no issue with the bulbs for sure

I am never afraid to dash in where angels fear to tread !
Having confirmed it as a K25 then start wiggling around the area of the headstock ie where the loom flexes. If nothing then consider carefully taking apart the switch assembly on the handlebar - take photos as you go to help reinstall.
Remeber that after 15 years of hard work/being left out in all weathers/pampered garage queen (delete as appropriate) it is still 15 yeats old. Juveniles are always the most unpredictable!

with a bulb error warning doubt its this but.... you can code the bike to leave the lights off - not all markets mandate the
"lets pretend wearing out my bulb filament can ever make cars drivers bother to look"

if you check the manual doesn't it confirm

Lamp F is an issue at the front
Lamp R is an issue at the back

Dumb question but I don't know the bike

Does it have separate fuses for high and low beam ?

Partly
It depends on the model year and other factors

There is according to the manual

LampF
LampR
Lamps

Which are

Lamps front , Lamps Rear & Lamps general

However it's not a perfect system - my MY06 gs gave me a LampF, error, so i changed the dip bulb, still had a Lampf error - no lights out / not working

Only when someone mentioned about the voltage modulation on the rear twin filament bulb, did i discover that one filament had blown

If the OP would post his model year it would help

My bike got the point where dipped beam bulbs were constantly blowing. Continuity tests with a multimeter showed a break in the wiring (inside the insulation so not visible) somewhere between the connectors on the loom, and the lamp itself.
I cut the connectors off, cut the wiring from the lamp as close to it as possible, did what many might consider a bodge job with bullet connectors to wire it all back together again but 5 years later I've only had to replace the bulb once.

No such thing as a dumb question
There are no fuses per-se on these bikes. The CANBUS system operates solid state relays which have overcurrent protections, like a circuit-breaker. They are reset by the CANBUS system.

Thanks, didn’t know that

have a look at the connecting pin thingy where the 2 bladed prongs go into / onto the rear housing. My 2010 melted them, i cut and inserted a ceramic blade fuse holder(if thats the right word). Bulbs didnt blow after that. Might be more of an explanation than my gibbering...holder
