mate i had the gold box batts from halfords,,,, the non road legal ones and they was wicked it first then they got a little pants


turns out they burn the silver covering on the reflector and made em worse


buy a new set of lamps,,,, gonna have to be pattern ones though and use the back section of you lamp though to fit your grill back on and you will have mint lights again



HID is the only real way to get decent lights as the sierra ones are pants anyway


new pattern ones first though
