Hey up my friends again, posted a spot on here a week ago about new set of LEDS I fitted,with your help I sorted the problem,but now looking at the rear sidelights,sidelights on there own are good,brake lights on there own good but when sidelights are on and press the brake pedal there is no difference, any ideas to help me out again, thanks

Sounds like you've wired the brake filaments as the side?
