Why do the headlights come on when you depress the brake pedal?mrs just recently changed the brake light bulbs.any clues pliz?

 

wrong brake light bulbs?

 

Silly girl got the bulbs wrong or fitten them wrong

Never let a woman do a mans work

 

 

cheeRS lads

 

they're twin pole on them dont go to halfrauds tho local motorfactors best bet

 

I bet the bulbs are in the wrong way round.

 

dont think you can put em in the wrong way round without forcing em the pins on the side arent symetrical

 

just swapped them n still headlights go on when u brake??

 

youve prob got a single filament bulb in there instead of correct twin filament.as u press brake pedal as its a single bulb its back feeding through sidelight circuit.

 

What he said

 

will have a looksy...cheers

 

if i remove them bulbs n leave em out shud stop the headlights coming on then?

 

Yup

 

I would try that. Ive had c few vans at work where the drivers have put bulbs in the rear and when the press the brake the side lights have come on cause they have had single filiment bulbs in as mentioned above.

 

As mentioned, if it happened immediately after changing the bulb then check the bulb is correct. Also be worth checking the earth point in the boot as i've had weird problems such as all the indicators coming on dimly under braking when my earth had come loose
