I've had my 87Z na for about two weeks and is currently working out the usual bugs. The main one that im concerned with is my flickering headlights. When i first turned on my lights and checked my h&l beam, i only had one. I think its the low beam, because when i pull my switch to blink my lights ,no lights. When im driving about 3-5 mph, the lights are ok, its when i increase my speed, the lights began to flicker almost to a strobelike effect. i've replaced the light, still the same, checked the wiring ,no breaks, also no dash lights, i don't know if this is connected or not, but if someone has had this problem or know how to point me in the right direction i would be most HAPPY. ps someone told me to check the bulb control relay, i have no idea the location or the how to
