rear Break light on sv650s

[gedcarney]

Hi does any one know how to get to the rear break bulb on a sv650s o6 model. Thanks ged

Hi Ged, try searching "rear brake light pointy". You will probably find what you need in a previous post. Pretty sure your brake lights will be by LED bulbs.

Hi you would think,,,, but no posts out there.

Yes, I have just had a look myself and you are right! Not easy to find a relevant thread. I found this one....

Do you have a fault with the brake light?

[gedcarney]

same old problem... with rear switch on bikes lol. The tail light is working and the brake adjustment light spring is working so i need to check the rear bulb..but how do you get to it on a sv650 o6 model. If it not bulb then its the break rear lever spring switch. Thanks for your help.;)

Not sure what your symptoms are exactly. If the brake light is not coming on at all suggest use a voltmeter to see if you have switched current to the brake light unit (maybe at the connector between the rear light unit and the rest of the loom, which you should be able to access) when you operate the front lever and or brake pedal operated switch, with the ignition on. If you have current to the brake lights but no brake lights coming on, suspect a faulty light unit or poor connection from where you tested, to the unit. Hope that helps.

Hopefully someone else will be able to give a more detailed diagnostic. It will help if you describe your fault in detail.

Does the brake light work with the front brakes?

[gedcarney]

yes the front light break light works? so the back should work and it can not be the bulb!

Hi just to be clear i have a tail light and front break light but no rear break light. I wanted to access the buld just to check, but do not know how to access the back break bulb. thanks ged

Oh OK, that suggests the light unit/bulbs are good. Have a look at the circuit for the foot brake switch and or the switch adjustment.

[gedcarney]

ok will do

Rear light on the pointy is an LED sealed unit - no bulbs to replace.

However, as the brake light works with the front brake then the light unit is fine and the problem must lie with the rear switch or its associated wiring.


I don't have a standard set-up but guess it's a fairly normal switch of the type. If access is tight undo the two rearset bolts and displace it.


I reckon the problem is likely to be one or more of the following;


- The switch needs adjusting (big plastic nut on the switch body). Operate the switch by hand to easily check if the switch is still working.
- The entire switch has come out its holder and is waving about in the breeze
- the spring operating the switch is broken or stretched
- the switch is mechanically broken (body or plunger). Replace it.
- the switch is electrically broken. Replace it.
- the associated wiring or connector is damaged


That's assuming you have a standard switch and it's not been replaced with a pressure switch (e.g. following installation of aftermarket rearsets).

The switch on the pedal is notoriously rubbish. They often come on, but go off again with increased pressure, often just totally fail. I think I have replaced 5 over the years.

Thanks for all your advice guys.
