Gq head lights

[zmaster]

Just my 2c worth.
Had the same problem when I bought the GQ, lights were worse than crap.
First I upgraded the wiring loom with heavy 6mm cable, relays and ceramic plugs.
Made a huge difference to the original sealed bulbs, much bighter but still yellow.
The original wires are a joke, they look like they wouldn't cope with LED's.
Next upgrade was the Narva reflectors and higher wattage globes, the higher wattage made no difference to light output.
Next came the philips 55/60w crystal 4300 globes, awsome white light, like daylight.
The Narva reflectors come with parkers, nice touch, but you need to grind the backplate to make them fit.
Narvas have a waterproof boot, but its not much of a seal, I used some Dow Corning silicon grease, the stuff sparkies use to waterproof wiring, to seal them, also works great at sealing and protecting door rubbers. Holden recommend the grease to stop door rubbers squealing and creaking.
