ive purchased a retrofit hid kit for my bmw e92 angel eyes however im having problems fitting it in. i connected it correctly (i think!) but the light kept flickering. Has anyone put such a kit on their e92? or would you recommend putting in leds? ive been doing some research and ive seen that PIAA seems to be the brightest, although they are very expensive. Has anyone put this particular kit and if so is it bright enough?
