Car - trueno gt-apex

motor - 4ag 16v

use - daily

problem - headlights were working fine for say a year, then low beams both died, sometimes could wriggle wiring and theyd flicker on and off, now one high beam has died so i cant really drive in the night

occurs/started when - start of this year ?

my guess is just wiring ? if i got a whole hid kit wiring and bulbs etc would that solve problem ? due for an upgrade anyway
