headlights help

hi i have a 1996 nissan primera se the other their day driving down the road and went into a big bump and ever since when i brake my headlights come on any one help

The double element may have crossed each other, If your not sure
change both rear brake light bulbs !

Let me know how u get on! :)

I agree with above. Once my mate put single filament bulbs in the brake light holders, which have two positive terminals. When she braked, the headlights came on.
