Well ive been taking the zed out once a week over the winter ust to keep her running but got an intermitent lighting issue,sometimes ike tonight all the front lights come on,most of the time only the left hand lights come on.im guessing this is a loose wire?,lights were ok before the winter cold,where would i star to look for problems?

there are different fuses that could be related..

 

Footwell - Headlights (Exterior lamps, clearance, licence, tail & Side marker) Battery section - 1st row 3rd from left.

Engine bay - main fuse box - Headlamp fuses x2 and relays, also check the earth under the fuse box.

 

JDM & UK cars have different earths for the headlights and the earths are different UK has earth wire but JDM earths at the headlights to chassis (from memory)

 

check/replace fuses and swap relays around, same colour ones are interchangeable.

 

Also check that there is no water leaking on to the footwell fuse box, this will cause corrosion and all kinds of problems with the electrics.

 

 

good luck.
