Headlight low beam is dim but high beam is full force how can this be fixed

SOURCE: main beam warning light stays on but no main

Hi and welcome to FixYa,

Initial checks would be:

• continuity of the bright / dim filaments of the headlight;
• the headlight bulb socket;
• +12 when switch on bright on the yellow wire;
• +12 when switch on dim on the green wire.

this is normal for an r6. the lights are set up as endurance lights from the factory

i have a 2005 fz6 fazer with the same problem and the problem is a good one with hard answers. the right hand light is set at a different angle to the left so is designed to point in a different direction to the one on the right. its just very tricky to re align the beam settings afterwards to stop blinding a motorist infront of you. i paid the garage to do this very same problem.

hi...yes the high beam & pass light use the high beam element in the bulb....no this sounds a bit daft/obvious....but have you changed/check#ed the bulb...the low beam element hasnt blown...has it???...for the price of a bulb i would change this...hope this helps

Yes it annoys me also - always looks like one head light blown in my opinion but this is how they are set up and is very common for the newer bikes.
