On my 2003 400ex, when I press the brake, the brake light doesn't turn on. Is there two bulbs in the back or is it a electrical problem? Thanks

 

No buddy it's not a problem at all, in the back it's a one filament bulb, and electrical is an two wire.It means that there is no possible way that when you put the brakes on, the light comes on,
It is design to turn on when your lights are on ...not for brake....
And second,you don't have any switch on either of the brake handle ( Foot or handlebar )....

So your 400ex is perfectally normal....But some places the law demands to have a brake light.....speedometer and mirrors..(left side)

Thanks

The 400ex didn't get brake lights until 2005. 2005 models also got reverse and 450R stlye plastic and headlights.
